Possible to Grep within .gz file without uncompress first?
When uncompressed the file size is over 800 megs, I wanted to know if I can search for a string within the compressed .gz file without uncompressing...

well your going to have to decompress it in one way, but you don't have to store the uncompressed data

Code:
zcat /file.gz | grep string


that will decompress it and pipe it to grep, so it will take a lot of CPU, but its won't store anything to the hard drive
