Hi,

I guess Gnu Zip for VMS give zgrep feature. Gnu Zip you can find on open vms freeware site:

http://h71000.www7.hp.com/openvms/freeware/index.html

Check for V6 freeware CD.

Good luck,
Regards,
Lokesh

the latest gzip for vms is here
http://www.oooovms.dyndns.org/gnv/gzip/

I don't know if it does zgrep.

Hello Mohammad,

zgrep is not part of gzip. Actually at least on my system it is a shell script doing the decompress "under the hood".

A simple solution would be something along the lines

pipe gunzip -c file.ext-gz | search sys$pipe:

When you say "like zgrep" it is not clear whether the archives are gzip archives for which you simply want a zgrep implementation, or ZIP archives that you want to search in a manner analogous to what zgrep does for gzip archives.

For ZIP archives, there is a zipGrep.pl script in the examples directory of the Perl extension Archive::Zip. See:

http://search.cpan.org/~nedkonz/Archive-Zip-1.10/

You will also need to install the Compress::Zlib extension, and, of course, Perl.
