Hello,

I'd like to make a grep over all files between / directory and all directories between recursively.

When I made grep 'myexpression' / or
grep 'myexpression' * or something like this it returns me nothing
while I know there's at least one file containing my expression

Can someone help me ???

Many thanks in advance

Did you try this ?

sorry I tried but -r is not a valid option for grep

The '-r' option probably is available only on GNU grep. Try this: This will go through every file on the system and do a grep on each one.

(if you have permission to read the file)
