bunzip2

QNX SDP8.0Utilities ReferenceUtilities

Decompress files (POSIX, toybox)

Syntax:

bunzip2 [-cfktv] [file...]

Runs on:

QNX OS

Options:

-c: Force the output to standard output.
-f: Force decompression. (If the file doesn't end in .bz, replace the original).
-k: Keep (i.e., don't delete) input files (-c and -t imply this).
-t: Test the integrity of the specified files.
-v: Verbose output; a second v makes the utility more verbose.
file: The pathname of the file that is decompressed.

Description:

The bunzip2 utility decompresses listed files that have been compressed with bzip2 (e.g., file.bz becomes file). If no files are listed, bunzip2 reads from standard input.

This utility is provided as part of the toybox package. For information on how to enable it, see toybox.
