Problem

How to use the zgrep command: Grep text patterns from files within compressed files. More information: <https://manned.org/zgrep>.

Solution

zgrep — Grep text patterns from files within compressed files. More information: <https://manned.org/zgrep>.

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

zgrep {{pattern}} {{path/to/compressed_file}}

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

zgrep {{--context|--before-context|--after-context}} 3 {{pattern}} {{path/to/compressed_file}}

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

zgrep {{[-i|--ignore-case]}} {{pattern}} {{path/to/compressed_file}}

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

zgrep {{[-c|--count]}} {{pattern}} {{path/to/compressed_file}}

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

zgrep {{[-v|--invert-match]}} {{pattern}} {{path/to/compressed_file}}

Grep a compressed file for multiple patterns:

zgrep {{[-e|--regexp]}} "{{pattern_1}}" {{[-e|--regexp]}} "{{pattern_2}}" {{path/to/compressed_file}}

Use extended regex (supports ?, +, {}, (), and |):

zgrep {{[-E|--extended-regexp]}} {{regex}} {{path/to/file}}
