bunzip2
Decompress bzip2 compressed files
TLDR
Decompress a file (removes the .bz2 original)
$ bunzip2 [file.txt.bz2]
Decompress keeping the compressed file$ bunzip2 -k [file.txt.bz2]
Decompress to stdout (useful for piping)$ bunzip2 -c [file.txt.bz2] > [file.txt]
Test file integrity without decompressing$ bunzip2 -t [file.txt.bz2]
Force overwrite of existing output files$ bunzip2 -f [file.txt.bz2]
SYNOPSIS
bunzip2 [options] [file...]
DESCRIPTION
bunzip2 decompresses files compressed with bzip2. It's equivalent to `bzip2 -d` and removes the .bz2 file after successful decompression.
The tool is a companion to bzip2 for extracting compressed files.
PARAMETERS
-k, --keep
Keep compressed file-f, --force
Overwrite existing files-c, --stdout
Write to standard output-t, --test
Test file integrity-v, --verbose
Verbose mode-q, --quiet
Suppress warnings-s, --small
Reduce memory usage at the cost of speed (uses about 2.5 MB per file)
CAVEATS
Removes original .bz2 file unless -k used. Requires memory proportional to compression block size. Cannot decompress corrupted files.
HISTORY
bunzip2 was included with bzip2 since its creation by Julian Seward in 1996.
