bzgrep - Man Page

• 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"

Bzgrep is used to invoke the grep on bzip2-compressed files. All options specified are passed directly to grep. If no file is specified, then the standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep.

If bzgrep is invoked as bzegrep or bzfgrep then egrep or fgrep is used instead of grep. If the GREP environment variable is set, bzgrep uses it as the grep program to be invoked. For example:

   for sh:  GREP=fgrep  bzgrep string files
   for csh: (setenv GREP fgrep; bzgrep string files)
