zgrep

Grep text patterns from files within compressed file (equivalent to grep -Z).

• Grep a pattern in a compressed file (case-sensitive):

zgrep {pattern} {path/to/compressed/file}

• Grep a pattern in a compressed file (case-insensitive):

zgrep -i {pattern} {path/to/compressed/file}

• Output count of lines containing matched pattern in a compressed file:

zgrep -c {pattern} {path/to/compressed/file}

• Display the lines which don’t have the pattern present (Invert the search function):

zgrep -v {pattern} {path/to/compressed/file}

• Grep a compressed file for multiple patterns:

zgrep -e "{pattern_1}" -e "{pattern_2}" {path/to/compressed/file}

• Use extended regular expressions (supporting `?`, `+`, `{}`, `()` and `|`):

zgrep -E {regular_expression} {path/to/file}

• Print 3 lines of [C]ontext around, [B]efore, or [A]fter each match:

zgrep -{C|B|A} {3} {pattern} {path/to/compressed/file}
