[gentoo-user] bash script question

[Adam Carter]

I want to use an if/then that tests for the existence of a string in 4
files. Usually I do this by checking the exit code of grep, when i'm
checking a single file. However, I cant get the syntax right for multiple
checks.



To troubleshoot I’ve dropped back to just checking two files, and i’ve
tried things like



If [ $(grep blah file1.txt) –a $(grep blah file2.txt) ]; then



But this matches if grep fails both times as well as when it matches both
time. Any ideas?
