.SH NAME
Zupdate \- recompress bzip2, gzip, xz files to lzip files
.SH SYNOPSIS
.B zupdate
[\fIoptions\fR] [\fIfiles\fR]
.SH DESCRIPTION
Zupdate recompresses files from bzip2, gzip, and xz formats to lzip format.
The originals are compared with the new files and then deleted.
Only regular files with standard file name extensions are recompressed,
other files are ignored.
Compressed files are decompressed and then recompressed on the fly; no
temporary files are created.
The lzip format is chosen as destination because it is by far the most
appropriate for long\-term data archiving.
.PP
If the lzip compressed version of a file already exists, the file is
skipped unless the '\-\-force' option is given. In this case, if the
comparison fails, an error is returned and the original file is not
deleted. The operation of zupdate is meant to be safe and not produce
any data loss. Therefore, existing lzip compressed files are never
overwritten nor deleted.
.PP
Exit status is 0 if all the compressed files were successfully
recompressed (if needed), compared and deleted. Non\-zero otherwise.

9 Zupdate
*********
Zupdate recompresses files from bzip2, gzip, and xz formats to lzip
format. The originals are compared with the new files and then deleted.
Only regular files with standard file name extensions are recompressed,
other files are ignored. Compressed files are decompressed and then
recompressed on the fly; no temporary files are created. The lzip format
is chosen as destination because it is by far the most appropriate for
long-term data archiving.
If the lzip compressed version of a file already exists, the file is
skipped unless the `--force' option is given. In this case, if the
comparison fails, an error is returned and the original file is not
deleted. The operation of zupdate is meant to be safe and not produce
any data loss. Therefore, existing lzip compressed files are never
overwritten nor deleted.
The names of the original files must have one of the following
extensions: `.bz2', `.tbz', `.tbz2', `.gz', `.tgz', `.xz', `.txz'. The
files produced have the extensions `.lz' or `.tar.lz'.
The format for running zupdate is:
zupdate [OPTIONS] [FILES]
Exit status is 0 if all the compressed files were successfully
recompressed (if needed), compared and deleted. Non-zero otherwise.
Zupdate supports the following options:
`-f'
`--force'
Do not skip a file for which a lzip compressed version already
exists. `--force' compares the content of the input file with the
content of the lzip file and deletes the input file if both
contents are identical.
`-l'
`--lzip-verbose'
Pass a `-v' option to the lzip compressor so that it shows the
compression ratio for each file processed. Using lzip 1.15 and
newer, a second `-l' shows the progress of compression. Use it
together with `-v' to see the name of the file.
`-q'
`--quiet'
Quiet operation. Suppress all messages.
`-r'
`--recursive'
Operate recursively on directories.
`-v'
`--verbose'
Verbose mode. Show the files being processed. A second `-v' also
shows the files being ignored.
`-0 .. -9'
Set the compression level of lzip. By default zupdate passes `-9'
to lzip.

Zupdate recompresses files from bzip2, gzip, and xz formats to lzip

other files are ignored. Compressed files are decompressed and then
recompressed on the fly; no temporary files are created. The lzip format
is chosen as destination because it is by far the most appropriate for
long-term data archiving.
If the lzip compressed version of a file already exists, the file is
skipped unless the @samp{--force} option is given. In this case, if the
comparison fails, an error is returned and the original file is not
deleted. The operation of zupdate is meant to be safe and not produce
any data loss. Therefore, existing lzip compressed files are never
overwritten nor deleted.
The names of the original files must have one of the following
extensions: @samp{.bz2}, @samp{.tbz}, @samp{.tbz2}, @samp{.gz},
@samp{.tgz}, @samp{.xz}, @samp{.txz}. The files produced have the
extensions @samp{.lz} or @samp{.tar.lz}.
The format for running zupdate is:
@example
zupdate [@var{options}] [@var{files}]
@end example
@noindent
Exit status is 0 if all the compressed files were successfully
recompressed (if needed), compared and deleted. Non-zero otherwise.
Zupdate supports the following options:
@table @samp
@item -f
@itemx --force
Do not skip a file for which a lzip compressed version already exists.
@samp{--force} compares the content of the input file with the content
of the lzip file and deletes the input file if both contents are
identical.
@item -l
@itemx --lzip-verbose
Pass a @samp{-v} option to the lzip compressor so that it shows the
compression ratio for each file processed. Using lzip 1.15 and newer, a
second @samp{-l} shows the progress of compression. Use it together with
@samp{-v} to see the name of the file.

@item -v
@itemx --verbose
Verbose mode. Show the files being processed. A second @samp{-v} also
shows the files being ignored.
@item -0 .. -9
Set the compression level of lzip. By default zupdate passes @samp{-9}
to lzip.
