Nearly correct. Try this:

perl -pe 's{(\( .*? \))}{$1 =~ y/ //dr}gex' file.txtor a little shorter and maybe more robust:

awk -F= 'FNR==NR{f1[FNR]=$0;next} {print $1 "_" f1[FNR], $2}' file1 OFS="=" file2

awk '(getline tmp < "file1") { print $1 "_" tmp FS $2}' FS="=" file2

Strange. I vaguely remember we had a similar problem quite some time ago, but can't find the solution.

I like the shell solution in post#2, it is also a bit closer to the attempt in post#1.

Hello Matthew, you could do something like:

How about (untested)
grep -Eo "String1|String2|String3" file.txt | sort | uniq -c

Change this:

if [ $? -eq 0 ]; then

wait $script3
rm -f ${LOCKFILE}
elif [ $? -eq 1 ]; then
rm -f ${LOCKFILE}

Your TIME_INTERVAL variable is not expanded by the shell, so your results may not be the desired ones.

Like Don Cragun said, I really don't see a point in your goal, and why you try to reinvent cron, but if you really want to do:
