Changes in version 1.12:
|
Changes in version 1.13:
|
||||||
|
|
||||||
The zutils configuration file 'zutilsrc' has been renamed to 'zutils.conf'.
|
The detection of bzip2 files with no compressed blocks has been fixed.
|
||||||
Zutils now looks for the configuration file in $XDG_CONFIG_HOME/zutils.conf
|
(Error introduced in version 1.9).
|
||||||
instead of $HOME/.zutilsrc. (XDG_CONFIG_HOME defaults to $HOME/.config).
|
|
||||||
(Suggested by Adam Tuja).
|
|
||||||
|
|
||||||
In zcat, zcmp, zdiff, and zgrep, the option '-O, --force-format' now can
|
When zcat, zcmp, zdiff, or zgrep need to try compressed file names, gzip
|
||||||
force also "uncompressed" format.
|
(.gz) is now tried before bzip2 (.bz2).
|
||||||
|
|
||||||
zcmp now accepts the option '-H, --hexadecimal' to print byte values in
|
When only one compressed file is passed to zcmp or zdiff, they now try to
|
||||||
hexadecimal instead of octal.
|
compare it with a compressed file of any of the remaining formats if the
|
||||||
|
corresponding uncompressed file does not exist.
|
||||||
|
|
||||||
In zcmp:
|
zcmp now reports EOF on empty file like GNU cmp:
|
||||||
The long name of option '-s' has been changed to '--script' following a
|
"zcmp: EOF on FILE which is empty".
|
||||||
similar change made to GNU ed.
|
|
||||||
|
|
||||||
The short name '-q' has been assigned to options '--quiet' and '--silent'.
|
File diagnostics in zupdate have been reformatted as 'PROGRAM: FILE: MESSAGE'.
|
||||||
|
|
||||||
Option '-q' now only suppresses diagnostic messages written to stderr.
|
The variable MAKEINFO has been added to configure and Makefile.in.
|
||||||
|
|
||||||
Option '-s' now only suppresses messages about file differences written to
|
|
||||||
stdout or stderr.
|
|
||||||
|
|
||||||
Option '-l, --list' is now different from option '-v, --verbose', which
|
|
||||||
now undoes the effect of '--quiet'.
|
|
||||||
|
|
||||||
zcmp now prints byte and line in EOF message like GNU cmp:
|
|
||||||
"zcmp: EOF on FILE after byte B, in line L".
|
|
||||||
|
|
||||||
zgrep now also accepts the following options: '-G, --basic-regexp',
|
|
||||||
'--label=<label>', '--line-buffered', '-P, --perl-regexp', '--silent',
|
|
||||||
'-T, --initial-tab', '-U, --binary', and '-Z, --null'.
|
|
||||||
(Reported by Chris Jamboretz and Leah Neukirchen).
|
|
||||||
|
|
||||||
ztest now exits with status 2 if an uncompressed file has a compressed file
|
|
||||||
name extension, or if a compressed file has a wrong compressed extension.
|
|
||||||
|
|
||||||
zupdate now accepts option '-d, --destdir' to write recompressed files to
|
|
||||||
another directory. This allows, for example, recompressing files from a
|
|
||||||
read-only file system to another place without needing to copy or link them
|
|
||||||
to the destination directory first.
|
|
||||||
|
|
||||||
zupdate now accepts option '-e, --expand-extensions', which makes it expand
|
|
||||||
combined file name extensions; tgz --> tar.lz.
|
|
||||||
|
|
||||||
zupdate now also accepts option '-i, --ignore-errors', which makes it ignore
|
|
||||||
non-fatal errors. (Suggested by Antoni Sawicki).
|
|
||||||
|
|
||||||
All utilities now support compress'd (.Z) files through gzip. For this to
|
|
||||||
work, the gzip program used (for example GNU gzip) must be able to
|
|
||||||
decompress .Z files.
|
|
||||||
|
|
||||||
At verbosity level 1 (2 for zdiff and zgrep) or higher, '-V, --version' now
|
|
||||||
prints the versions of the compressors used (limited by option '-M, --format').
|
|
||||||
(The compressors used must support option '-V' for this to work).
|
|
||||||
|
|
||||||
Diagnostics caused by invalid arguments to command line options now show the
|
|
||||||
argument and the name of the option.
|
|
||||||
|
|
||||||
It has been documented in the manual that the data format is detected by its
|
|
||||||
magic bytes, not by the file name extension.
|
|
||||||
|
|
||||||
The testsuite now tests tarlz (if available) as compressor for zupdate.
