Lziprecover is able to repair slightly damaged +files, produce a correct file by merging the good parts of two or more +damaged copies, extract data from damaged files, decompress files and test +integrity of files. .PP Lziprecover can repair perfectly most files with small errors (up to one single\-byte error per member), without the need of any extra redundance at all. Losing an entire archive just because of a corrupt byte near the beginning is a thing of the past. .PP -Lziprecover can also produce a correct file by merging the good parts of -two or more damaged copies, extract data from damaged files, decompress -files and test integrity of files. +Lziprecover can remove the damaged members from multimember files, for +example multimember tar.lz archives. .PP -Lziprecover provides random access to the data in multimember files; it -only decompresses the members containing the desired data. +Lziprecover provides random access to the data in multimember files; it only +decompresses the members containing the desired data. .PP -Lziprecover facilitates the management of metadata stored as trailing -data in lzip files. +Lziprecover facilitates the management of metadata stored as trailing data +in lzip files. .PP Lziprecover is not a replacement for regular backups, but a last line of defense for the case where the backups are also damaged. @@ -45,14 +48,14 @@ write to standard output, keep input files \fB\-d\fR, \fB\-\-decompress\fR decompress .TP -\fB\-D\fR, \fB\-\-range\-decompress=\fR<range> -decompress a range of bytes (N\-M) to stdout +\fB\-D\fR, \fB\-\-range\-decompress=\fR<n\-m> +decompress a range of bytes to stdout .TP \fB\-f\fR, \fB\-\-force\fR overwrite existing output files .TP \fB\-i\fR, \fB\-\-ignore\-errors\fR -make '\-\-range\-decompress' ignore data errors +all errors in \fB\-D\fR, format errors in \fB\-l\fR, \fB\-\-dump\fR .TP \fB\-k\fR, \fB\-\-keep\fR keep (don't delete) input files @@ -84,14 +87,14 @@ be verbose (a 2nd \fB\-v\fR gives more) \fB\-\-loose\-trailing\fR allow trailing data seeming corrupt header .TP -\fB\-\-dump\-tdata\fR -dump trailing data to standard output +\fB\-\-dump=\fR<list>:d:t +dump members listed/damaged, tdata to stdout .TP -\fB\-\-remove\-tdata\fR -remove trailing data from files in place +\fB\-\-remove=\fR<list>:d:t +remove members, tdata from files in place .TP -\fB\-\-strip\-tdata\fR -copy files to stdout without trailing data +\fB\-\-strip=\fR<list>:d:t +copy files to stdout stripping members given .PP If no file names are given, or if a file is '\-', lziprecover decompresses from standard input to standard output. @@ -107,7 +110,7 @@ Report bugs to lzip\-bug@nongnu.org .br Lziprecover home page: http://www.nongnu.org/lzip/lziprecover.html .SH COPYRIGHT -Copyright \(co 2018 Antonio Diaz Diaz. +Copyright \(co 2019 Antonio Diaz Diaz.
