ok, let me ask you this then, lets say I enter a users name, I read in the value, while name is not equal to x I do something, I then grep a file to search if the value of name exists in there, if so I don't want it to do anything, if not, then I want it to do something, then exit the if block go back where I left off in while loop, check value of name variable, if name is not x continue looping, once name is an x end program. How would I do that then? In other words how do you compare the value of name to value of name that I grep from another file?

ZGREP(1) General Commands Manual ZGREP(1)
NAME
zgrep - search possibly compressed files for a regular expression
SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename...
DESCRIPTION
Zgrep invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code:
(-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, then the
standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep.
If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.
EXIT CODE
2 - An option that is not supported was specified.
