I am pleased to announce the release of zutils 1.4.

Zutils is a collection of utilities able to deal with any combination of compressed and uncompressed files transparently. If any given file, including standard input, is compressed, its decompressed content is used. Compressed files are decompressed on the fly; no temporary files are created.


These utilities are not wrapper scripts but safer and more efficient C++ programs. In particular the "--recursive" option is very efficient in those utilities supporting it.

The provided utilities are zcat, zcmp, zdiff, zgrep, ztest and zupdate.
The supported formats are bzip2, gzip, lzip and xz.
The compressor to be used for each format is configurable at runtime.

zcat, zcmp, zdiff, and zgrep are improved replacements for the shell scripts provided by GNU gzip. ztest is unique to zutils. zupdate is similar to gzip's znew.

The homepage is at http://www.nongnu.org/zutils/zutils.html

The sources can be downloaded from http://download.savannah.gnu.org/releases/zutils/

The sha1sum is:
f49b73f455dd11a1f181bef1bf946bf24bdb5fdc  zutils-1.4.tar.lz

This release is also GPG signed. You can download the signature by appending ".sig" to the URL.

Changes in version 1.4:

  * The option "--format" has been renamed to "-O, --force-format".

* The option "-M, --format=<list>" now restricts automatic search to the formats listed in the comma-separated <list>. This change introduces a backward incompatibility with previous versions of zutils.

* If the pattern begins with '-', zgrep now prepends "-e" before passing it to grep. ('zgrep -- -pattern file' now works as expected).

* The targets "install-compress", "install-strip-compress", "install-info-compress" and "install-man-compress" have been added to the Makefile.


Please send bug reports and suggestions to zutils-bug@nongnu.org

Antonio Diaz, zutils author and maintainer.
