zgrep

Grep text patterns from files within compressed file (equivalent to grep -Z). More information: https://manned.org/zgrep.

• 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|--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 regular expressions (supporting ?, +, {}, () and |):

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