I'm in my bash book and looking on web but can't seem to resolve this simple problem. $ if [ -n "grep A121 myfile.csv" ]; then echo "null"; fi null $ if [ -n "grep A125 myfile.csv" ]; then echo "null"; fi null A125 definitely is null when I just run the grep command in the quotes but A121 definitely is not null. What am I missing on the if/null operator here?
