lzfgrep
Search compressed files for fixed strings
TLDR
Search for a fixed string in a compressed file
$ lzfgrep [string] [file.lz]
Case-insensitive search$ lzfgrep -i [string] [file.lz]
Show line numbers with matches$ lzfgrep -n [string] [file.lz]
Count matching lines$ lzfgrep -c [string] [file.lz]
Search across multiple compressed files$ lzfgrep [string] [file1.lz] [file2.lz]
List files containing matches$ lzfgrep -l [string] [*.lz]
SYNOPSIS
lzfgrep [grepoptions] [**-e**] pattern [file_...]
DESCRIPTION
lzfgrep searches for fixed strings in files that may be compressed with xz, lzma, gzip, or bzip2. It is equivalent to lzgrep -F and is faster than regex-based search for literal string patterns. Files are automatically decompressed on the fly before searching.
lzfgrep is provided as part of xz-utils for backward compatibility with LZMA Utils. If no file is specified, standard input is decompressed if necessary and fed to grep.
PARAMETERS
All options are passed directly to grep(1). Common options include:
-i
Case-insensitive matching.-n
Show line numbers.-c
Print count of matching lines only.-l
Print names of files with matches.-v
Invert match (show non-matching lines).-w
Match whole words only.-e pattern
Specify the pattern explicitly.
CAVEATS
When reading from standard input, gzip and bzip2 compressed files are not supported. All options are passed directly to grep.
