finding the string within folder using shell command-CodePudding

How to find all files within folder containing specific text (string) if text found return 1 if not return 0 in linux?

grep -r "34161FA8203289722240CD40" /usr/lib/cgi-bin/ParkingSoft/api/v3/LaneApi/ETC/MywebSocket /*.txt

Try This:

grep -rwl 'PATH/targetFolder/' -e 'target_string' | awk -F "/" '{print $NF}'

The above command returns the name of all files that contains the target_string.

To know about -rwl check this answer, However awk -F "/" '{print $NF}' just split the grep output and return the last part. (file name in your case)

The -q option returns (exit code) 1 when no match is found. Try:

echo "string" | grep -q in && echo yes
echo "string" | grep -q out && echo yes

In your case:

searchdir="/usr/lib/cgi-bin/ParkingSoft/api/v3/LaneApi/ETC/MywebSocket "
if [ ! -d "$searchdir" ]; then
  echo "Check searchdir. Is 'ETC' really in uppercase and is `Mywebsocket ` including a space?"
else
  if grep -rwq '34161FA8203289722240CD40' "${searchdir}/*.txt; then
    echo "String found in one of the files."
