zegrep

Find extended regular expression patterns in compressed files using egrep. More information: https://www.unix.com/man-page/freebsd/1/zegrep/.

• Search for extended regular expressions (supporting ?, +, {}, () and |) in a compressed file (case-sensitive):
  zegrep "{{search_pattern}}" {{path/to/file}}
• Search for extended regular expressions (supporting ?, +, {}, () and |) in a compressed file (case-insensitive):
  zegrep --ignore-case "{{search_pattern}}" {{path/to/file}}
• Search for lines that do not match a pattern:
  zegrep --invert-match "{{search_pattern}}" {{path/to/file}}
• Print file name and line number for each match:
  zegrep --with-filename --line-number "{{search_pattern}}" {{path/to/file}}
• Search for lines matching a pattern, printing only the matched text:
  zegrep --only-matching "{{search_pattern}}" {{path/to/file}}
• Recursively search files in a compressed file for a pattern:
  zegrep --recursive "{{search_pattern}}" {{path/to/file}}
