.TH XZNEW 1
|
||||
.SH NAME
|
||||
xznew \- recompress .gz or .tgz files to .xz files
|
||||
.SH SYNOPSIS
|
||||
.B xznew
|
||||
[ -ftv9PK] [ name.gz ... ]
|
||||
.SH DESCRIPTION
|
||||
.I xznew
|
||||
recompresses files from .gz (gzip) format to .xz (xz) format.
|
||||
If you want to recompress a file already in xz format, rename the file
|
||||
to force a .xz extension then apply xznew.
|
||||
.SH OPTIONS
|
||||
.TP
|
||||
.B \-f
|
||||
Force recompression from .gz to .xz format even if a .xz file already exists.
|
||||
.TP
|
||||
.B \-t
|
||||
Tests the new files before deleting originals.
|
||||
.TP
|
||||
.B \-v
|
||||
Verbose. Display the name and percentage reduction for each file compressed.
|
||||
.TP
|
||||
.B \-9
|
||||
Use the slowest compression method (optimal compression).
|
||||
.TP
|
||||
.B \-P
|
||||
Use pipes for the conversion to reduce disk space usage.
|
||||
.TP
|
||||
.B \-K
|
||||
Keep a .gz file when it is smaller than the .xz file
|
||||
.SH "SEE ALSO"
|
||||
xz(1), gzip(1)
|
||||
.SH BUGS
|
||||
.I xznew
|
||||
does not maintain the time stamp with the -P option if
|
||||
.I cpmod(1)
|
||||
is not available and
|
||||
.I touch(1)
|
||||
does not support the -r option.
