zfgrep

Matches fixed strings in possibly compressed files. Equivalent to grep -F with input decompressed first if necessary. More information: https://manned.org/zfgrep.

• Search for an exact string in a file:
  zfgrep {{search_string}} {{path/to/file}}
• Count the number of lines that match the given string in a file:
  zfgrep --count {{search_string}} {{path/to/file}}
• Show the line number in the file along with the matching lines:
  zfgrep --line-number {{search_string}} {{path/to/file}}
• Display all lines except those that contain the search string:
  zfgrep --invert-match {{search_string}} {{path/to/file}}
• List only filenames whose content matches the search string at least once:
  zfgrep --files-with-matches {{search_string}} {{path/to/file1 path/to/file2 ...}}
