grep in unix version True 64

Dear All

I have a unix version (True 64 ) and i want to grep some of data from zipping files with extention(.gz) altyhough i wouldn't to unzip these files, so can you help me grep these data in one command without unzip files.

Note:- In othe version of unix (i forget that version) i used the following command (zgrep -----) to grep data from zipping files.

So if you can help please advice.

thanks a lot.
