Zutils 1.8-pre2 is ready for testing here
http://download.savannah.gnu.org/releases/zutils/zutils-1.8-pre2.tar.lz

The sha256sum is:
9db85aa598604e5cd3a053597c884959c448182fb2f743c0e93570d26c91e1c0 zutils-1.8-pre2.tar.lz

Please, test it and report any bugs you find.

Zutils is a collection of utilities able to process 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 utilities provided are zcat, zcmp, zdiff, zgrep, ztest and zupdate.
The formats supported are bzip2, gzip, lzip and xz.
Zutils uses external compressors. 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


Changes in this version:

* A buffer overrun has been fixed in zcat which happened with some input files when the '-v, --show-nonprinting' option was used (or indirectly enabled).

* The option '-R, --dereference-recursive', which recursively follows symbolic links, has been added to zcat, zgrep, ztest and zupdate.

* The option '-r, --recursive' now skips symlinks that are encountered recursively.

* If no files are given to zcat, zgrep, ztest and zupdate, a recursive search will now examine the current working directory.

  * Recursive directory loops are now detected.

* zcat and zgrep now ignore directories given in the command line if '--recursive' is not specified, instead of reporting an error.

* Extra trailing slashes are now removed from directories given in the command line before recursing into them.

* zcat and zgrep now show the right error when they can't open an input file instead of showing "No such file or directory".

* Killed decompressors are now waited for, preventing failure caused by too many open pipes.

* Test and document that if a file fails to decompress, zcat, zgrep and ztest continue processing the rest of the files.

* Test and document that if an error happens while recompressing a file, zupdate exits immediately without recompressing the rest of the files.

Antonio Diaz, zutils author and maintainer.

If you are distributing software in xz format, please consider using lzip instead. See http://www.nongnu.org/lzip/lzip_benchmark.html#xz1 and http://www.nongnu.org/lzip/xz_inadequate.html
