zfgrep

Matches fixed strings in possibly compressed files. Equivalent to grep --fixed-strings 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 {{[-c|--count]}} {{search_string}} {{path/to/file}}

• Show the line number in the file along with the matching lines:

zfgrep {{[-n|--line-number]}} {{search_string}} {{path/to/file}}

• Display all lines except those that contain the search string:

zfgrep {{[-v|--invert-match]}} {{search_string}} {{path/to/file}}

• List only filenames whose content matches the search string at least once:

zfgrep {{[-l|--files-with-matches]}} {{search_string}} {{path/to/file1 path/to/file2 ...}}
