Zutils 1.11-rc1 is ready for testing here

The sha256sum is:
c76ea29d5bde860bdfa984d8caec923b205825fa46ad4fb366b2d807d018113c zutils-1.11-rc1.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 file given, 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 option "--recursive" 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, xz, and zstd.
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.

Changes in this version:

* A race has been fixed in zcmp and zdiff that sometimes made them return 1 (files differ) instead of 2 (trouble) when a compressor is not found or when a wrong format is forced.

* In case of error in an argument to a command line option, all tools now show the name of the option.

* In case of error in a numerical argument to a command line option, zcmp now shows the name of the option and the range of valid values.

* Support for the zstd format has been added to all tools. This allows, among other things, zupdating zstd files to lzip format for long-term archiving, and using zcmp along with the unzcrash tool (from the lziprecover package) to test zstd files.

If you care about data safety and long-term archiving, please consider using lzip. See http://www.nongnu.org/lzip/lzip_benchmark.html
