The +.BR \-\-listq " and " \-\-discard +options allow the management of the queue. + +All splitting, joining and queueing operations produce informative +messages on standard output; these may safely be ignored. +. +.SH COMMANDS +.TP +.BR \-s ", " \-\-split " \fIcomplete-archive\fP [\fIprefix\fP]" +Splits a single Debian binary package into several parts. + +The parts are named +.IB prefix . N of M .deb +where +.I N +is the part number, starting at 1, and +.I M +is the total number of parts (both in decimal). + +If no +.I prefix +is supplied then the +.I complete-archive +filename is taken, including directory, with any trailing +.B .deb +removed. +.TP +.BR \-j ", " \-\-join " \fIpart\fP..." +Joins the parts of a package file together, reassembling the original +file as it was before it was split. + +The part files given as arguments must be all the parts of exactly the +same original binary file. Each part must occur exactly once in the +argument list, though the parts to not need to be listed in order. + +The parts must of course all have been generated with the same part +size specified at split time, which means that they must usually have +been generated by the same invocation of +.BR "dpkg\-split \-\-split" . + +The parts' filenames are not significant for the reassembly process. + +By default the output file is called +.IB package _ version _ arch .deb\fR. + +.TP +.BR \-I ", " \-\-info " \fIpart\fP..." +Prints information, in a human-readable format, about the part file(s) +specified. Arguments which are not binary package parts produce a +message saying so instead (but still on standard output). +.TP +.BR \-a ", " "\-\-auto \-o" " \fIcomplete-output part\fP" +Automatically queue parts and reassemble a package if possible. + +The +.I part +specified is examined, and compared with other parts of the same +package (if any) in the queue of packages file parts. + +If all parts of the package file of which +.I part +is a part are available then the package is reassembled and written to +.I complete-output +(which should not usually already exist, though this is not an +error). + +If not then the +.I part +is copied into the queue and +.I complete-output +is not created. + +If +.I part +is not a split binary package part then +.B dpkg\-split +will exit with status \fB1\fP; if some other trouble occurs then it will +exit with status \fB2\fP. + +The +.BR \-\-output " or " \-o +option must be supplied when using +.BR \-\-auto . +(If this were not mandatory the calling program would not know what +output file to expect.) +.TP +.BR \-l ", " \-\-listq +Lists the contents of the queue of packages to be reassembled. + +For each package file of which parts are in the queue the output gives +the name of the package, the parts in the queue, and the total number +of bytes stored in the queue. +.TP +.BR \-d ", " \-\-discard " [\fIpackage\fP...]" +This discards parts from the queue of those waiting for the remaining +parts of their packages. + +If no +.I package +is specified then the queue is cleared completely; if any are +specified then only parts of the relevant package(s) are deleted. +.TP +.BR \-?

The default is 450 KiB. +.TP +.BR \-o ", " \-\-output " \fIcomplete-output\fP" +Specifies the output file name for a reassembly. + +This overrides the default for a manual reassembly +.RB ( \-\-join ) +and is mandatory for an automatic queue-or-reassemble +.RB ( \-\-auto ). +.TP +.BR \-Q ", " \-\-npquiet +When doing automatic queue-or-reassembly +.B dpkg\-split +usually prints a message if it is given a +.I part +that is not a binary package part. This option suppresses this +message, to allow programs such as +.B dpkg +to cope with both split and unsplit packages without producing +spurious messages. +.TP +.B \-\-msdos +Forces the output filenames generated by +.B \-\-split +to be msdos-compatible. + +This mangles the prefix - either the default derived from the input +filename or the one supplied as an argument: alphanumerics are +lowercased, plus signs are replaced by +.BR x 's +and all other characters are discarded. + +The result is then truncated as much as is necessary, and filenames of +the form +.IB "prefixN" of M .deb +are generated. +. +.SH EXIT STATUS +.TP +.B 0 +The requested split, merge, or other command succeeded. +.B \-\-info +commands count as successful even if the files are not binary package +parts. +.TP +.B 1 +Only occurs with +.B \-\-auto +and indicates that the +.I part +file was not a binary package part. +.TP +.B 2 +Fatal or unrecoverable error due to invalid command-line usage, +a file that looked like a package part file but was corrupted, or +interactions with the system, such as accesses to the database, +memory allocations, etc. +. +.SH ENVIRONMENT +.TP +.B DPKG_COLORS +Sets the color mode (since dpkg 1.18.5). +The currently accepted values are: \fBauto\fP (default), \fBalways\fP and +\fBnever\fP. +.TP +.B SOURCE_DATE_EPOCH +If set, it will be used as the timestamp (as seconds since the epoch) in +the \fBdeb\-split\fP(5)'s \fBar\fP(5) container. +. +.SH FILES +.TP +.I %ADMINDIR%/parts +The default queue directory for part files awaiting automatic +reassembly. + +The filenames used in this directory are in a format internal to +.B dpkg\-split +and are unlikely to be useful to other programs, and in any case the +filename format should not be relied upon. +. +.SH BUGS +Full details of the packages in the queue are impossible to get +without digging into the queue directory yourself. + +There is no easy way to test whether a file that may be a binary +package part is one. +. +.SH SEE ALSO +.BR deb (5), +.BR deb\-control (5), +.BR dpkg\-deb (1), +.BR dpkg (1). -- cgit v1.2.3
