Quick Question on sed command in shell script
Hello,
I have the following line in one of my shell scripts. It works fine when the search string($SERACH_STR) exists in the logfile($ALERTLOG) but if the search string does not exist this line errors out at run time. Is there a way to make this line return 0 if it is not able to find the search string in the log file? START_LINE=`grep -n "$SEARCH_STR" $ALERTLOG | head -1 | sed 's/:/ /' | awk '{print $1}'` Thanks. |
