  • Search for an exact string in a file:
    fgrep search_string path/to/file
  • Search only lines that match entirely in files:
    fgrep -x path/to/file1 path/to/file2
  • Count the number of lines that match the given string in a file:
    fgrep -c search_string path/to/file
  • Show the line number in the file along with the line matched:
    fgrep -n search_string path/to/file
  • Display all lines except those that contain the search string:
    fgrep -v search_string path/to/file
  • Display filenames whose content matches the search string at least once:
    fgrep -l search_string path/to/file1 path/to/file2
