Matches fixed strings in files. Equivalent to grep -F. More information:

  • Search for an exact string in a file:

fgrep {{search_string}} {{path/to/file}}

  • Search only lines that match entirely in one or more files:

fgrep -x {{search_string}} {{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 ...}}
