Polecenie bzip2

Wykonanie, użycie: File compression and decompression utility similar to gzip, but uses a different algorithm and encoding method to get better compression. bzip2 replaces each file in filenames with a compressed version of the file and with a .bz2 extension appended. bunzip2 decompresses each file compressed by bzip2 (ignoring other files, except to print a warning). bzcat decompresses all specified files to standard output, and bzip2recover is used to try to recover data from damaged files.

Additional related commands include bzcmp, which compares the contents of bzipped files; bzdiff, which creates diff (difference) files from a pair of bzip files; bzgrep, to search them; and the bzless and bzmore commands, which apply the more and less commands to bzip output, as bzcat does with the cat command. See cat, cmp, diff, and grep for information on how to use those commands

Opcje wykonania bzip2 w konsoli

--

End of options; treat all subsequent arguments as filenames.

 -dig

Set block size to dig × 100 KB when compressing, where dig is a single digit from 1 to 9.

 -c, --stdout

Compress or decompress to standard output.

 -d, --decompress

Force decompression.

 -f, --force

Force overwrite of output files. Default is not to overwrite. Also forces breaking of hard links to files.

 -k, --keep

Keep input files; don't delete them.

 -L, --license, -V, --version

Print license and version information, and exit.

 -q, --quiet

Print only critical messages.

 --repetitive-fast, --repetitive-best

Obsolete flags, occasionally useful in versions earlier than 0.9.5 (which has an improved sorting algorithm) for providing some control over the algorithm.

 -s, --small

Use less memory, at the expense of speed.

 -t, --test

Check the integrity of the files, but don't actually compress them.

 -v, --verbose

Verbose mode. Show the compression ratio for each file processed. Add more -v's to increase the verbosity.

 -z, --compress

Force compression, even if invoked as bunzip2 or bzcat.

 -1, --fast

Perform fast compression, creating a relatively large file. This has no effect on decompression. Higher numbers, up to 9, create progressively better-compressed files. See -9, --best.

 -9, --best

Get the best possible compression, although it will take longer.
