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 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
