bzfgrep

Search bzip2 files for fixed string patterns

TLDR

Search for a fixed string in a bzip2 compressed file

$ bzfgrep "[string]" [path/to/file.bz2]

Search case-insensitively

$ bzfgrep -i "[string]" [path/to/file.bz2]

Print line numbers with matches

$ bzfgrep -n "[string]" [path/to/file.bz2]

Search multiple compressed files

$ bzfgrep "[string]" [file1.bz2] [file2.bz2]

Count matching lines

$ bzfgrep -c "[string]" [path/to/file.bz2]

SYNOPSIS

bzfgrep [fgrepoptions] [**-e**] pattern [filename..._]

bzfgrep searches possibly bzip2-compressed files for lines matching a fixed string pattern. It transparently decompresses .bz2 files before searching and passes all options directly to fgrep.Unlike bzgrep or bzegrep, bzfgrep interprets the pattern as a literal string rather than a regular expression. This makes it faster for simple string searches and avoids the need to escape special characters.If no file is specified, bzfgrep reads from standard input, decompressing if necessary.

PARAMETERS

All fgrep options are supported, including:-i

Case-insensitive matching

-n

Print line numbers

-c

Print only a count of matching lines

-v

Invert match (show non-matching lines)

-l

Print only filenames containing matches

-e pattern

Specify the pattern (useful if pattern starts with -)

INSTALL

sudo apt install bzip2

sudo dnf install bzip2

sudo pacman -S bzip2

sudo apk add bzip2

sudo zypper install bzip2

brew install bzip2

nix profile install nixpkgs#bzip2

CAVEATS

The GREP environment variable can be set to specify an alternate grep program. The pattern is treated as a fixed string, not a regular expression. For regex searches, use bzgrep or bzegrep.
