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}}
