Test data:
$ echo file content > f1 && echo filx content > f2
$ bzip2 f1 f2
Other setup:
$ git clone https://gitlab.com/bzip2/bzip2.git
$ ln -nv ./bzip2/bzdiff bzcmp
$ chmod u+x ./bzcmp
In regards to bzcmp, this is a very simple way to check for the issue:
# ubuntu's
$ bzcmp f1.bz2 f2.bz2
cmp: invalid --ignore-initial value '/tmp/bzdiff.8kHv0B9tBJ'
cmp: Try 'cmp --help' for more information.
# original's (https://gitlab.com/bzip2/bzip2)
$ ./bzcmp f1.bz2 f2.bz2
- /tmp/bzdiff.vpXGvPfv5I differ: char 4, line 1
In regard to bzdiff, this is a very simple way to check for the issue:
# ubuntu's
$ bzdiff -y -W20 f1.bz2 f2.bz2
diff: invalid option -- ' '
diff: Try 'diff --help' for more information.
# original's (https://gitlab.com/bzip2/bzip2)
$ bash bzip2/bzdiff -y -W20 f1.bz2 f2.bz2
file | filx
I think the culprit is the /usr/bin/bzdiff script. Here the difference between ubuntu's and the original one
