In addition to zgrep, we need bzgrep.

I guess you need something like zutils[1].

[1] http://www.nongnu.org/zutils/zutils.html


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 - 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.

The supported compressors are bzip2, gzip, lzip and xz.


Regards,
Antonio.
