+# bzgrep
+
+> Find patterns in bzip2 compressed files using grep.
+> More information: <https://manned.org/bzgrep>.
+
+- Search for a pattern within a compressed file:
+
+`bzgrep "{{search_pattern}}" {{path/to/file}}`
+
+- Use extended regular expressions (supports `?`, `+`, `{}`, `()` and `|`), in case-insensitive mode:
+
+`bzgrep --extended-regexp --ignore-case "{{search_pattern}}" {{path/to/file}}`
+
+- Print 3 lines of context around, before, or after each match:
+
+`bzgrep --{{context|before-context|after-context}}={{3}} "{{search_pattern}}" {{path/to/file}}`
+
+- Print file name and line number for each match:
+
+`bzgrep --with-filename --line-number "{{search_pattern}}" {{path/to/file}}`
+
+- Search for lines matching a pattern, printing only the matched text:
+
+`bzgrep --only-matching "{{search_pattern}}" {{path/to/file}}`
+
+- Recursively search files in a bzip2 compressed tar archive for a pattern:
+
+`bzgrep --recursive "{{search_pattern}}" {{path/to/tar/file}}`
+
+- Search stdin for lines that do not match a pattern:
+
+`cat {{/path/to/bz/compressed/file}} | bzgrep --invert-match "{{search_pattern}}"`
