rgrep

Recursively find patterns in files using regular expressions.

Equivalent to `grep -r`.

• 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}
