Hi Jean.
It isn't clear to me from the bug report whether by "$DIST_IO_SORT is
empty" means the environment variable is not set, or whether the file it
points to is empty. It is clear that you interpreted this to be the
latter, but I don't think that's what was intended. But the following
leads me to believe he was referring to an unset environment variable.
With $junk undefined,
sh returns 1 from [ -f $junk ]
bash returns 0
With junk defined and pointing to an empty file,
both sh and bash return 0 when I do [ -f $junk ]
Finally, the output of the mkisofs command in the bug report makes me
wonder if there is something missing from the commandline. It says:
mkisofs: No such file or directory. Can't open sort file list -quiet
That makes me think the commandline args are shifted due to a missing
arg, which could come from an undefined environment variable.
So before saying it looks OK, I'd like to check with the bugfiler what
he meant. Looks to me like he was referring to an undefined environment
variable, not to an environment variable which points to an empty file.
Thanks,
Jack
