Zutils is a collection of utilities able to deal with 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 - Decompresses and copies files to standard output.
Zcmp - Decompresses and compares two files byte by byte.
Zdiff - Decompresses and compares two files line by line.
Zgrep - Decompresses and searches files for a regular expression.
Ztest - Tests integrity of compressed files.
Zupdate - Recompresses files to lzip format.

The formats supported are bzip2, gzip, lzip, xz, and zstd.
The compressor to be used for each format is configurable at runtime.
