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?
