/Shell/Bash/Bash check if string in file

Bash check if string in file

Just use grep with flags 'F' (fixed string), 'x' (exact match) and 'q'
(quiet output) in order to check if a word string is in a file
if grep -Fxq "string" file.txt; then #do some code...#; fi

Bash if file contains string

if grep -q SomeString "$File"; then
  Some Actions # SomeString was found
fi
