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

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

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

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

• Grep a compressed file for multiple patterns:

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

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