Find patterns in files using regular expressions. More information: <https://www.gnu.org/software/grep/manual/grep.html>.

  • Search for a pattern within a file:
    grep "search_pattern" path/to/file
  • Search for an exact string (disables regular expressions):
    grep --fixed-strings "exact_string" path/to/file
  • Search for a pattern in all files recursively in a directory, showing line numbers of matches, ignoring binary files:
    grep --recursive --line-number --binary-files=without-match "search_pattern" path/to/directory
  • Use extended regular expressions (supports `?`, `+`, `{}`, `()` and `|`), in case-insensitive mode:
    grep --extended-regexp --ignore-case "search_pattern" path/to/file
  • Print 3 lines of context around, before, or after each match:
    grep --context|before-context|after-context=3 "search_pattern" path/to/file
  • Print file name and line number for each match with color output:
    grep --with-filename --line-number --color=always "search_pattern" path/to/file
  • Search for lines matching a pattern, printing only the matched text:
    grep --only-matching "search_pattern" path/to/file
  • Search `stdin` for lines that do not match a pattern:
    cat path/to/file | grep --invert-match "search_pattern"
