Description Peter Gantner (a.k.a. nephros) 2010-01-29 14:33:50 UTC

pbzip2 barfs when invoked like this:

cat file | pbzip2 -9 > file.bz2

this is what e.g. 'make bzimage' from the kernel does.

Therefore app-arch/pbzip2 +symlink breaks some scripts which expect original bzip2.

Reproducible: Always

Steps to Reproduce:

Actual Results:  
Parallel BZIP2 v1.0.5 - by: Jeff Gilchrist [http://compression.ca]         
[Jan. 08, 2009]             (uses libbzip2 by Julian Seward)               

Invalid command line: Not enough files given.  Aborting...

Usage: pbzip2 [-1 .. -9] [-b#cdfhklp#qrtVz] <filename> <filename2> <filenameN>
 -b#      : where # is the file block size in 100k (default 9 = 900k)
 -c       : output to standard out (stdout)
 -d       : decompress file
 -f       : force, overwrite existing output file
 -h       : print this help message
 -k       : keep input file, don't delete
 -l       : load average determines max number processors to use
 -p#      : where # is the number of processors (default: autodetect [4])
 -q       : quiet mode (default)
 -r       : read entire input file into RAM and split between processors
 -t       : test compressed file integrity
 -v       : verbose mode
 -V       : display version info for pbzip2 then exit
 -z       : compress file (default)
 -1 .. -9 : set BWT block size to 100k .. 900k (default 900k)

Example: pbzip2 -b15vk myfile.tar
Example: pbzip2 -p4 -r -5 myfile.tar second*.txt
Example: tar cf myfile.tar.bz2 --use-compress-prog=pbzip2 dir_to_compress/
Example: pbzip2 -d myfile.tar.bz2
