I sort of did need the 'if' because I took the line out of a context
from a bigger shell script that does more than this and reduced it down
to the simplest form first for my trial and error and then for the list.
Thanks though...I sort of had those in mind when I started but the
context gets deeper - thus the
if [ grep -c some_expression file -eq 0 ]; then ...
did the job nicely.
Heck, if you want to simplify even further, don't bother with the '['
command and just use the return code from 'grep':
if grep -q some_expression file; then
echo "grep found something"
