Subject: chmod isn't validating its output?
Dmitry,
I'm just curious whether we need to fix this or not in our coreutils
package. The following example demonstrates the issue. It's not a
bug, but is something we might want to fix and to submit upstream.
mother!galaxy:~$ ls -l sample.file
-rw------- 1 galaxy galaxy 0 2009-01-22 11:34 sample.file
mother!galaxy:~$ chmod g+o sample.file
mother!galaxy:~$ echo $?
0
mother!galaxy:~$ ls -l sample.file
-rw------- 1 galaxy galaxy 0 2009-01-22 11:34 sample.file
mother!galaxy:~$ rpm -qf `which chmod`
coreutils-5.93-owl2
mother!galaxy:~$
Note that I supplied chmod with weird permission symbol and it didn't
complain and hasn't returned any failure code.
Since we have one of the coreutils maintainers in out team :) I thought
it would be appropriate to ask here whether I should submit the bug
report to the coreutils developers or is this "feature" here on a
purpose? If it's the latter I would like to know why (just to learn
some history behind it :) )
