rgrep

Recursively find patterns in files using regular expressions. Equivalent to grep -r. More information: https://www.gnu.org/software/grep/manual/grep.html.

• Recursively search for a pattern in the current working directory:

rgrep "{{search_pattern}}"

• Recursively search for a case-insensitive pattern in the current working directory:

rgrep --ignore-case "{{search_pattern}}"

• Recursively search for an extended regular expression pattern (supports ?, +, {}, () and |) in the current working directory:

rgrep --extended-regexp "{{search_pattern}}"

• Recursively search for an exact string (disables regular expressions) in the current working directory:

rgrep --fixed-strings "{{exact_string}}"

• Recursively search for a pattern in a specified directory (or file):

rgrep "{{search_pattern}}" {{path/to/file_or_directory}}
