Public bug reported:
Hi all,
I found a bug in "split".
I want to tar some files but some of them have wrong permissions. tar puts out
an exit code 2 "Cannot open: Permission denied". That is good because in my
script I can catch this error and react to this.
$ tar -c -f /tmp/test.tar -C /media/testpath testfile ; echo $?
tar: testfile: Cannot open: Permission denied
tar: Exiting with failure status due to previous errors
2
Unfortunately my tar directory is too big to save it in one file on my
filesystem that I have to split the archive. But doing this "split" does
not get the error code 2 from standard input (tar) and does not break as
it should:
$ tar -c -f - -C /media/testpath testfile | split - ; echo $?
tar: testfile: Cannot open: Permission denied
tar: Exiting with failure status due to previous errors
0
In the end I got a tar file without files that have no permissions and
my script does not break because of error code 0.
