Version 1.0.8, 13-Jul-2019. usage: test_package [flags and input files in any order] -h --help print this message -d --decompress force decompression -z --compress force compression -k --keep keep (don't delete) input files -f --force overwrite existing output files -t --test test compressed file integrity -c --stdout output to standard out -q --quiet suppress noncritical error messages -v --verbose be verbose (a 2nd -v gives more) -L --license display software version & license -V --version display software version & license -s --small use less memory (at most 2500k) -1 .. -9 set block size to 100k .. 900k --fast alias for -1 --best alias for -9 If invoked as `bzip2', default action is to compress. as `bunzip2', default action is to decompress. as `bzcat', default action is to decompress to stdout. If no file names are given, bzip2 compresses or decompresses from standard input to standard output. You can combine short flags, so `-v -4' means the same as -v4 or -4v, &c.
