grep for multiple strings in a single line

I need to check if any of the strings "Added/Changed/Fixed/Deleted" are in a commit log message. I am writing an svn precommit hook, and the expected commit comment should have one of these 4 strings in the message. The code I am using is as below ``` REPOS=$1 TXN=$2 SVN="/usr/bin/svn"; SVNLOOK="/usr/bin/svnlook"; $SVNLOOK log "$REPOS" -t "$TXN" | \ grep "[a-zA-Z0-9]" > /dev/null GREP_STATUS=$? if [ $GREP_STATUS -ne 0 ] then "${ECHO}" "No Log comments present" >> "${LOG}" echo "Your commit has been blocked because you didn't give any log message" 1>&2 echo "Please write a log message describing the purpose of your changes and" 1>&2 echo "then try committing again. -- Thank you" 1>&2 exit 1 fi ``` In the above code, ``` $SVNLOOK log "$REPOS" -t "$TXN" ``` will give me the commit message that the user has entered. Now I have to check for the presence of any of the strings "Added, Changed, Fixed, Deleted" in the message. That is, ``` if (any of the above 4 strings are not present), exit 1 ``` I tried with ``` $($SVNLOOK log -t "$TXN" "$REPOS" | grep -q "Added\|Changed\|Fixed\|Deleted"|) ``` but it doesnt seem to be working.
