bzfgrep

search possibly bzip2 compressed files for a regular expression

TLDR

Search for lines matching the list of search strings separated by new lines in a compressed file (case-sensitive)

$ bzfgrep "[search_string]" [path/to/file]
copy


Search for lines matching the list of search strings separated by new lines in a compressed file (case-insensitive)
$ bzfgrep --ignore-case "[search_string]" [path/to/file]
copy


Search for lines that do not match the list of search strings separated by new lines in a compressed file
$ bzfgrep --invert-match "[search_string]" [path/to/file]
copy


Print file name and line number for each match
$ bzfgrep --with-filename --line-number "[search_string]" [path/to/file]
copy


Search for lines matching a pattern, printing only the matched text
$ bzfgrep --only-matching "[search_string]" [path/to/file]
copy


Recursively search files in a bzip2 compressed tar archive for the given list of strings
$ bzfgrep --recursive "[search_string]" [path/to/file]
copy

SYNOPSIS

bzgrep [ grep_options ] [ -e ] pattern filename... bzegrep [ egrep_options ] [ -e ] pattern filename... bzfgrep [ fgrep_options ] [ -e ] pattern filename...

DESCRIPTION

Bzgrep is used to invoke the grep on bzip2-compressed files. All op‐ tions 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)
