grep -q returns true if the string is found or false, and prints no output to stdout.

You test the return value to see if the string was there or not.

Thanks Jim.I dont know what grep doesnt have the -q option, all I know is that I get this error when I try to use it:

UX:grep: ERROR: Illegal option -- q
UX:grep: TO FIX: Usage: grep -hblcnsvi pattern file . . .

Tony, run the command "uname -a" and tell us what it says. I also am wondering which version of unix you are using.

The -q option on grep is required by posix. So it would seem that your version of unix is not posix compliant.

...OK!
Bravo, Ygor! I came to these forums KNOWING that the answer must dwell within. Registered, searched, and found--1st try Smilie

Thank you!

For me, I wanted to find any instance of our "old" domain name, while EXCLUDING email addresses. Finally!

Code:
find . -type f ! -exec grep -q '@olddomain.com' {} \; -exec grep -q 'olddomain.com' {} \; -print
