Zutils is a collection of utilities able to deal with any combination of compressed and non-compressed 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, and ztest. The supported compressors are bzip2, gzip, lzip, and xz.
Release Notes: The output of "zgrep -L" has been fixed (it behaved like "zgrep -l").
Release Notes: Decompressors are now invoked without the "-q" option unless explicitly requested, as some simplified implementations do not accept it.
Release Notes: Zgrep now shows file names by default when "--recursive" is selected. A deadlock in zcmp, which happens when the "-n" option was used, has been fixed.
Release Notes: Zgrep no longer prefixes the file name to the output by default when searching one file. A portability issue with Solaris 9 has been (hopefully) fixed.
Release Notes: This release adds minor fixes. The new option "--format", which forces the use of a given compression format, has been added to all utilities. The target "install-bin" has been added to the Makefile.
