Das native +Dateiformat ist das \fB.xz\fP\-Format, aber das veraltete, von den +LZMA\-Dienstprogrammen verwendete Format sowie komprimierte Rohdatenströme +ohne Containerformat\-Header werden ebenfalls unterstützt. Außerdem wird die +Dekompression des von \fBlzip\fP verwendeten \fB.lz\fP\-Formats unterstützt. +.PP +\fBxz\fP komprimiert oder dekomprimierte jede \fIDatei\fP entsprechend des +gewählten Vorgangsmodus. Falls entweder \fB\-\fP oder keine Datei angegeben ist, +liest \fBxz\fP aus der Standardeingabe und leitet die verarbeiteten Dateien in +die Standardausgabe.

Sollte das Kopieren der Gruppe +fehlschlagen, werden die Zugriffsrechte so angepasst, dass jenen Benutzern +der Zugriff auf die Zieldatei verwehrt bleibt, die auch keinen Zugriff auf +die Ursprungs\-\fIDatei\fP hatten. Das Kopieren anderer Metadaten wie +Zugriffssteuerlisten oder erweiterter Attribute wird von \fBxz\fP noch nicht +unterstützt. +.PP +Sobald die Zieldatei erfolgreich geschlossen wurde, wird die +Ursprungs\-\fIDatei\fP entfernt. Dies wird durch die Option \fB\-\-keep\fP +verhindert. Die Ursprungs\-\fIDatei\fP wird niemals entfernt, wenn die Ausgabe +in die Standardausgabe geschrieben wird oder falls ein Fehler auftritt. +.PP +Durch Senden der Signale \fBSIGINFO\fP oder \fBSIGUSR1\fP an den \fBxz\fP\-Prozess +werden Fortschrittsinformationen in den Fehlerkanal der Standardausgabe +geleitet. Dies ist nur eingeschränkt hilfreich, wenn die +Standardfehlerausgabe ein Terminal ist. Mittels \fB\-\-verbose\fP wird ein +automatisch aktualisierter Fortschrittsanzeiger angezeigt. +. +.SS Speicherbedarf +In Abhängigkeit von den gewählten Kompressionseinstellungen bewegt sich der +Speicherverbrauch zwischen wenigen hundert Kilobyte und mehreren +Gigabyte. Die Einstellungen bei der Kompression einer Datei bestimmen dabei +den Speicherbedarf bei der Dekompression. Die Dekompression benötigt +üblicherweise zwischen 5\ % und 20\ % des Speichers, der bei der Kompression +der Datei erforderlich war. Beispielsweise benötigt die Dekompression einer +Datei, die mit \fBxz \-9\fP komprimiert wurde, gegenwärtig etwa 65\ MiB +Speicher. Es ist jedoch auch möglich, dass \fB.xz\fP\-Dateien mehrere Gigabyte +an Speicher zur Dekompression erfordern. +.PP +Insbesondere für Benutzer älterer Systeme wird eventuell ein sehr großer +Speicherbedarf ärgerlich sein. Um unangenehme Überraschungen zu vermeiden, +verfügt \fBxz\fP über eine eingebaute Begrenzung des Speicherbedarfs, die +allerdings in der Voreinstellung deaktiviert ist. Zwar verfügen einige +Betriebssysteme über eingebaute Möglichkeiten zur prozessabhängigen +Speicherbegrenzung, doch diese sind zu unflexibel (zum Beispiel kann +\fBulimit\fP(1) beim Begrenzen des virtuellen Speichers \fBmmap\fP(2) +beeinträchtigen). +.PP +Die Begrenzung des Speicherbedarfs kann mit der Befehlszeilenoption +\fB\-\-memlimit=\fP\fIBegrenzung\fP aktiviert werden. Oft ist es jedoch bequemer, +die Begrenzung durch Setzen der Umgebungsvariable \fBXZ_DEFAULTS\fP +standardmäßig zu aktivieren, zum Beispiel +\fBXZ_DEFAULTS=\-\-memlimit=150MiB\fP. Die Begrenzungen können getrennt für +Kompression und Dekompression mittels \fB\-\-memlimit\-compress=\fP\fIBegrenzung\fP +und \fB\-\-memlimit\-decompress=\fP\fIBegrenzung\fP festgelegt werden. Die Verwendung +einer solchen Option außerhalb der Variable \fBXZ_DEFAULTS\fP ist kaum +sinnvoll, da \fBxz\fP in einer einzelnen Aktion nicht gleichzeitig Kompression +und Dekompression ausführen kann und \fB\-\-memlimit=\fP\fIBegrenzung\fP (oder \fB\-M\fP +\fIBegrenzung\fP) lässt sich einfacher in der Befehlszeile eingeben. +.PP +Wenn die angegebene Speicherbegrenzung bei der Dekompression überschritten +wird, schlägt der Vorgang fehl und \fBxz\fP zeigt eine Fehlermeldung an. Wird +die Begrenzung bei der Kompression überschritten, dann versucht \fBxz\fP die +Einstellungen entsprechend anzupassen, außer wenn \fB\-\-format=raw\fP oder +\fB\-\-no\-adjust\fP angegeben ist. Auf diese Weise schlägt die Aktion nicht fehl, +es sei denn, die Begrenzung wurde sehr niedrig angesetzt. Die Anpassung der +Einstellungen wird schrittweise vorgenommen, allerdings entsprechen die +Schritte nicht den Voreinstellungen der Kompressionsstufen. Das bedeutet, +wenn beispielsweise die Begrenzung nur geringfügig unter den Anforderungen +für \fBxz \-9\fP liegt, werden auch die Einstellungen nur wenig angepasst und +nicht vollständig herunter zu den Werten für \fBxz \-8\fP +. +.SS "Verkettung und Auffüllung von .xz\-Dateien" +Es ist möglich, \fB.xz\fP\-Dateien direkt zu verketten. Solche Dateien werden +von \fBxz\fP genauso dekomprimiert wie eine einzelne \fB.xz\fP\-Datei. +.PP +Es ist weiterhin möglich, eine Auffüllung zwischen den verketteten Teilen +oder nach dem letzten Teil einzufügen. Die Auffüllung muss aus Null\-Bytes +bestehen und deren Größe muss ein Vielfaches von vier Byte sein. Dies kann +zum Beispiel dann vorteilhaft sein, wenn die \fB.xz\fP\-Datei auf einem +Datenträger gespeichert wird, dessen Dateisystem die Dateigrößen in +512\-Byte\-Blöcken speichert. +.PP +Verkettung und Auffüllung sind für \fB.lzma\fP\-Dateien oder Rohdatenströme +nicht erlaubt. +. +.SH OPTIONEN +. +.SS "Ganzzahlige Suffixe und spezielle Werte" +An den meisten Stellen, wo ein ganzzahliges Argument akzeptiert wird, kann +ein optionales Suffix große Ganzzahlwerte einfacher darstellen.

The native file format is the +\&\fB.xz\fP format, but the legacy \fB.lzma\fP format used by LZMA Utils and raw +compressed streams with no container format headers are also supported. In +addition, decompression of the \fB.lz\fP format used by \fBlzip\fP is supported. +.PP +\fBxz\fP compresse ou décompresse chaque \fIfichier\fP en fonction du mode +d'opération choisi. Si aucun \fIfichier\fP n'est donné ou \fIfichier\fP est \fB\-\fP, +\fBxz\fP lit depuis l'entrée standard et écrit les données traitées sur la +sortie standard. \fBxz\fP refusera (affichera une erreur et ignorera le +\fIfichier\fP) d'écrire les données compressées sur la sortie standard si c'est +un terminal. De même, \fBxz\fP refusera de lire des données compressées depuis +l'entrée standard si c'est un terminal. +.PP +A moins que \fB\-\-sdout\fP ne soit indiqué, les \fIfichiers\fP autres que \fB\-\fP sont +écrits dans un nouveau fichier dont le nom est dérivé du nom de \fIfichier\fP +source\ : +.IP \(bu 3 +Lors de la compression, le suffixe du format de fichier cible (\fB.xz\fP ou +\&\fB.lzma\fP) est ajouté au nom de fichier source pour obtenir le nom de fichier +cible. +.IP \(bu 3 +When decompressing, the \fB.xz\fP, \fB.lzma\fP, or \fB.lz\fP suffix is removed from +the filename to get the target filename. \fBxz\fP also recognizes the suffixes +\&\fB.txz\fP and \fB.tlz\fP, and replaces them with the \fB.tar\fP suffix. +.PP +Si le fichier cible existe déjà, une erreur est affichée et le \fIfichier\fP +est ignoré. +.PP +Sauf s'il écrit dans la sortie standard, \fBxz\fP affichera un avertissement et +ignorera le \fIfichier\fP dans les cas suivants\ : +.IP \(bu 3 +\fIfichier\fP n'est pas un fichier normal.

Si la +copie du groupe échoue, les permissions sont modifiées pour que le fichier +cible ne soit pas accessible aux utilisateurs qui n'ont pas les droits +d'accès au \fIfichier\fP source. \fBxz\fP ne prend actuellement pas en charge la +copie d'autres métadonnées telles que les listes de contrôle d'accès ou les +attributs étendus. +.PP +Once the target file has been successfully closed, the source \fIfile\fP is +removed unless \fB\-\-keep\fP was specified. The source \fIfile\fP is never removed +if the output is written to standard output or if an error occurs. +.PP +Envoyer \fBSIGINFO\fP ou \fBSIGURSR1\fP au processus \fBxz\fP, lui fait afficher +l'information de progression sur l'erreur standard. Cela a un intérêt limité +car lorsque l'erreur standard est un terminal, utiliser \fB\-\-verbose\fP +affichera automatiquement un indicateur de progression du processus. +. +.SS "Utilisation de la mémoire" +L'utilisation de la mémoire par \fBxz\fP varie de quelques centaines de +kilo\-octets à plusieurs gigaoctects en fonction des paramètres de +compression. Les réglages utilisés lors de la compression d'un fichier +déterminent les besoins en mémoire pour la décompression. Habituellement la +décompression nécessite 5\% à 20\% de la quantité de mémoire utilisée pour +la compression du fichier. Par exemple, décompresser un fichier créé avec +\fBxz\-9\fP recquiert habituellement 65\ Mio de mémoire. Bien qu'il soit +possible d'avoir des fichiers \fB.xz\fP nécessitant plusieurs gigaoctets de +mémoire pour être décompressés. +.PP +Especially users of older systems may find the possibility of very large +memory usage annoying. To prevent uncomfortable surprises, \fBxz\fP has a +built\-in memory usage limiter, which is disabled by default. While some +operating systems provide ways to limit the memory usage of processes, +relying on it wasn't deemed to be flexible enough (for example, using +\fBulimit\fP(1) to limit virtual memory tends to cripple \fBmmap\fP(2)). +.PP +The memory usage limiter can be enabled with the command line option +\fB\-\-memlimit=\fP\fIlimit\fP. Often it is more convenient to enable the limiter +by default by setting the environment variable \fBXZ_DEFAULTS\fP, for example, +\fBXZ_DEFAULTS=\-\-memlimit=150MiB\fP. It is possible to set the limits +separately for compression and decompression by using +\fB\-\-memlimit\-compress=\fP\fIlimit\fP and \fB\-\-memlimit\-decompress=\fP\fIlimit\fP. +Using these two options outside \fBXZ_DEFAULTS\fP is rarely useful because a +single run of \fBxz\fP cannot do both compression and decompression and +\fB\-\-memlimit=\fP\fIlimit\fP (or \fB\-M\fP \fIlimit\fP) is shorter to type on the +command line. +.PP +If the specified memory usage limit is exceeded when decompressing, \fBxz\fP +will display an error and decompressing the file will fail. If the limit is +exceeded when compressing, \fBxz\fP will try to scale the settings down so that +the limit is no longer exceeded (except when using \fB\-\-format=raw\fP or +\fB\-\-no\-adjust\fP). This way the operation won't fail unless the limit is very +small. The scaling of the settings is done in steps that don't match the +compression level presets, for example, if the limit is only slightly less +than the amount required for \fBxz \-9\fP, the settings will be scaled down only +a little, not all the way down to \fBxz \-8\fP. +. +.SS "Concaténation et remplissage avec des fichiers .xz" +Il est possible de concaténer les fichiers \fB.xz\fP tels quel. \fBxz\fP +décompressera de tels fichiers comme s'ils étaient un unique fichier \fB.xz\fP. +.PP +It is possible to insert padding between the concatenated parts or after the +last part. The padding must consist of null bytes and the size of the +padding must be a multiple of four bytes. This can be useful, for example, +if the \fB.xz\fP file is stored on a medium that measures file sizes in +512\-byte blocks. +.PP +La concaténation et le remplissage ne sont pas autorisés avec les fichiers +\&\fB.lzma\fP ou les flux bruts. +. +.SH OPTIONS +. +.SS "Suffixes entiers et valeurs spéciales." +Dans la plupart des endroits où un argument entier est attendu, un suffixe +optionel permet d'indiquer facilement les grands entiers.

De obicei, instrumentul de +decomprimare are nevoie de 5% până la 20% din cantitatea de memorie de care +a avut nevoie instrumentul de comprimare la crearea fișierului. De exemplu, +decomprimarea unui fișier creat cu \fBxz \-9\fP necesită în prezent 65Mio de +memorie. Totuși, este posibil să aveți fișiere \fB.xz\fP care necesită câțiva +gigaocteți de memorie pentru decomprimare. +.PP +În special utilizatorii de sisteme mai vechi pot considera deranjantă +posibilitatea unei utilizări foarte mari a memoriei. Pentru a preveni +surprizele neplăcute, \fBxz\fP are încorporat un limitator de utilizare a +memoriei, care este dezactivat implicit. În timp ce unele sisteme de +operare oferă modalități de a limita utilizarea memoriei proceselor, bazarea +pe aceasta nu a fost considerată a fi suficient de flexibilă (de exemplu, +utilizarea \fBulimit\fP(1) pentru a limita memoria virtuală tinde să paralizeze +\fBmmap\fP(2)). +.PP +Limitatorul de utilizare a memoriei poate fi activat cu opțiunea din linia +de comandă \fB\-\-memlimit=\fP\fIlimita\fP. Adesea este mai convenabil să activați +limitatorul în mod implicit prin definirea variabilei de mediu +\fBXZ_DEFAULTS\fP, de exemplu, \fBXZ_DEFAULTS=\-\-memlimit=150MiB\fP. Este posibil +să stabiliți limitele separat pentru comprimare și decomprimare folosind +\fB\-\-memlimit\-compress=\fP\fIlimita\fP și \fB\-\-memlimit\-decompress=\fP\fIlimita\fP. +Utilizarea acestor două opțiuni în afara \fBXZ_DEFAULTS\fP este foarte rar +utilă, deoarece o singură rulare a \fBxz\fP nu poate face atât comprimarea, cât +și decomprimarea și \fB\-\-memlimit=\fP\fIlimita\fP (sau \fB\-M\fP \fIlimita\fP ) este mai +scurt de tastat pe linia de comandă. +.PP +Dacă limita de utilizare a memoriei specificată este depășită la +decomprimare, \fBxz\fP va afișa o eroare și decomprimarea fișierului va eșua. +Dacă limita este depășită la comprimare, \fBxz\fP va încerca să reducă valorile +stabilite astfel încât limita să nu mai fie depășită (cu excepția cazului în +care se utilizează opțiunea \fB\-\-format=raw\fP sau \fB\-\-no\-adjust\fP). În acest +fel, operațiunea nu va eșua decât dacă limita stabilită este foarte mică. +Scalarea valorilor stabilite se face în pași care nu se potrivesc cu +valorile prestabilite ale nivelului de comprimare, de exemplu, dacă limita +este doar puțin mai mică decât cantitatea necesară pentru \fBxz \-9\fP, valorile +stabilite vor fi reduse doar puțin , nu până la valoarea prestabilită a lui +\fBxz \-8\fP. +. +.SS "Concatenare și completare (prin umplere cu octeți nuli) cu fișiere .xz" +Este posibil să concatenați fișierele \fB.xz\fP așa cum sunt. \fBxz\fP va +decomprima astfel de fișiere ca și cum ar fi un singur fișier \fB.xz\fP. +.PP +Este posibil să se introducă umplutură între părțile concatenate sau după +ultima parte.

Alternativa +este să marcați că dimensiunea necomprimată este necunoscută și să folosiți +marcajul de sfârșit de încărcare pentru a indica unde ar trebui să se +oprească decomprimarea. LZMA Utils folosește această metodă atunci când +dimensiunea necomprimată nu este cunoscută, ceea ce este cazul, de exemplu, +când se folosesc conducte. +.PP +\fBxz\fP acceptă decomprimarea fișierelor \fB.lzma\fP cu sau fără marcaj de +sfârșit de încărcare, dar toate fișierele \fB.lzma\fP create de \fBxz\fP vor +folosi marcajul de sfârșit de încărcare și vor avea dimensiunea necomprimată +marcată ca necunoscută în antetul \fB.lzma\fP. Aceasta poate fi o problemă în +unele situații mai puțin frecvente. De exemplu, un instrument de +decomprimare \fB.lzma\fP încorporat într\-un dispozitiv poate funcționa numai cu +fișiere care au dimensiunea necomprimată cunoscută. Dacă întâmpinați +această problemă, trebuie să utilizați LZMA Utils sau LZMA SDK pentru a crea +fișiere \fB.lzma\fP cu dimensiunea necomprimată cunoscută. +. +.SS "Fișiere .lzma neacceptate" +Formatul \fB.lzma\fP permite valori \fIlc\fP de până la 8 și valori \fIlp\fP de până +la 4. LZMA Utils poate decomprima fișiere cu orice \fIlc\fP și \fIlp\fP, dar +creează întotdeauna fișiere cu \fBlc=3\fP și \fBlp=0\fP. Crearea de fișiere cu +alte \fIlc\fP și \fIlp\fP este posibilă cu \fBxz\fP și cu LZMA SDK. +.PP +Implementarea filtrului LZMA1 în liblzma necesită ca suma \fIlc\fP și \fIlp\fP să +nu depășească 4. Altfel, fișierele \fB.lzma\fP, care depășesc această +limitare, nu pot fi decomprimate cu \fBxz\fP. +.PP +LZMA Utils creează numai fișiere \fB.lzma\fP care au o dimensiune de dicționar +de 2^\fIn\fP (o putere de 2), dar acceptă fișiere cu orice dimensiune de +dicționar. liblzma acceptă numai fișierele \fB.lzma\fP care au dimensiunea de +dicționar de 2^\fIn\fP sau 2^\fIn\fP + 2^(\fIn\fP\-1). Acest lucru este pentru a +reduce numărul de „fals pozitiv” atunci când se detectează fișiere \fB.lzma\fP. +.PP +Aceste limitări nu ar trebui să fie o problemă în practică, deoarece practic +toate fișierele \fB.lzma\fP au fost comprimate cu opțiuni pe care liblzma le va +accepta. +. +.SS "Resturi rămase" +Când decomprimă, LZMA Utils ignoră în tăcere totul după primul flux +\&\fB.lzma\fP. În majoritatea situațiilor, aceasta este o eroare. Aceasta +înseamnă, de asemenea, că LZMA Utils nu acceptă decomprimarea fișierelor +\&\fB.lzma\fP concatenate. +.PP +Dacă au rămas date după primul flux \fB.lzma\fP, \fBxz\fP consideră că fișierul +este corupt, cu excepția cazului în care a fost utilizată opțiunea +\fB\-\-single\-stream\fP. Acest lucru poate rupe scripturile obscure(scrise +deficitar) care presupun că resturile rămase sunt ignorate. +. +.SH NOTE +. +.SS "Rezultatul comprimării poate varia" +Ieșirea exactă comprimată produsă din același fișier de intrare necomprimat +poate varia între versiunile XZ Utils, chiar dacă opțiunile de comprimare +sunt identice. Acest lucru se datorează faptului că instrumentul +codificator poate fi îmbunătățit (comprimare mai rapidă sau mai bună) fără a +afecta formatul fișierului. Ieșirea poate varia chiar și între compilările +diferite ale aceleiași versiuni XZ Utils, dacă sunt utilizate opțiuni +diferite de compilare. +.PP +Cele de mai sus înseamnă că odată ce opțiunea \fB\-\-rsyncable\fP a fost +utilizată, fișierele rezultate nu vor fi neapărat sincronizate cu rsync +decât dacă atât fișierele vechi, cât și cele noi au fost comprimate cu +aceeași versiune xz. Această problemă poate fi remediată dacă o parte a +implementării codificatorului este înghețată pentru a menține stabilă +ieșirea „rsyncabilă” între versiunile xz. +. +.SS "Instrumente de decomprimare .xz încorporate" +Implementările instrumentului de decomprimare \fB.xz\fP încorporat, cum ar fi +XZ Embedded, nu acceptă neapărat fișiere create cu tipuri de \fIverificare\fP a +integrității, altele decât \fBnone\fP și \fBcrc32\fP.

Наприклад, розпаковування файла, який створено з використанням \fBxz \-9\fP, у поточній версії потребує 65\ МіБ пам'яті.

Хоча у деяких операційних системах передбачено спосіб обмежити +використання пам'яті процесами, сподівання на його ефективність не є аж +надто гнучким (наприклад, використання \fBulimit\fP(1) для обмеження +віртуальної пам'яті призводить до викривлення даних \fBmmap\fP(2)). +.PP +Обмежувач пам'яті можна увімкнути за допомогою параметра командного рядка +\fB\-\-memlimit=\fP\fIобмеження\fP. Часто, зручніше увімкнути обмежувач на типовому +рівні, встановивши значення для змінної середовища \fBXZ_DEFAULTS\fP, +наприклад, \fBXZ_DEFAULTS=\-\-memlimit=150MiB\fP.

Це може призвести до проблем у +деяких нетипових ситуаціях. Наприклад, розпакувальник \fB.lzma\fP у вбудованому +пристрої може працювати лише з файлами, для яких відомий нестиснений +розмір. Якщо ви зіткнулися з цією проблемою, вам слід скористатися LZMA +Utils або LZMA SDK для створення файлів \fB.lzma\fP із відомим розміром +нестиснених даних. +. +.SS "Непідтримувані файли .lzma" +У форматі \fB.lzma\fP можливі значення \fIlc\fP аж до 8 і значення \fIlp\fP аж до +4. LZMA Utils можуть розпаковувати файли із будь\-якими значеннями \fIlc\fP і +\fIlp\fP, але завжди створюють файли з \fBlc=3\fP і \fBlp=0\fP. Створення файлів з +іншими значеннями \fIlc\fP і \fIlp\fP є можливим за допомогою \fBxz\fP і LZMA SDK. +.PP +Реалізація фільтра LZMA1 у liblzma потребує, щоби сума \fIlc\fP і \fIlp\fP не +перевищувала 4. Отже, файли \fB.lzma\fP, у яких перевищено обмеження, не може +бути розпаковано за допомогою \fBxz\fP. +.PP +LZMA Utils створюють лише файли \fB.lzma\fP, які мають розмір словника у 2^\fIn\fP +(степінь 2), але приймають файли із будь\-яким розміром словника. liblzma +приймає лише файли \fB.lzma\fP, які мають розмір словника 2^\fIn\fP або 2^\fIn\fP + +2^(\fIn\fP\-1). Так зроблено для зменшення помилок при виявленні файлів +\&\fB.lzma\fP. +.PP +Ці обмеження не мають призводити до проблем на практиці, оскільки практично +усі файли \fB.lzma\fP було стиснено з використанням параметрів, які приймає +liblzma. +. +.SS "Кінцевий мотлох" +При розпаковуванні LZMA Utils без повідомлень ігнорують усі дані після +першого потоку \fB.lzma\fP. У більшості випадків це пов'язано із вадою у +програмі. Це також означає, що у LZMA Utils не передбачено підтримки +розпаковування з'єднаних файлів \fB.lzma\fP. +.PP +Якщо після першого потоку \fB.lzma\fP лишилися дані, \fBxz\fP вважатиме файл +пошкодженим, якщо не було використано \fB\-\-single\-stream\fP.

Причиною цього є удосконалення у +кодувальнику (пришвидшення або краще стискання) без зміни формату +файлів. Виведені дані можуть бути різними навіть для різних збірок тієї +самої версії XZ Utils, якщо використано різні параметри збирання. +.PP +Написане вище означає, що після реалізації \fB\-\-rsyncable\fP файли\-результати +не обов'язково можна буде синхронізувати за допомогою rsyncable, якщо старий +і новий файли було стиснено за допомогою тієї самої версії xz.
