I'm not sure the exit code is useful in the general case. Something like
rm(1) seems to give the same exit code despite failing for different
reasons:
$ rm /tmp/root_owned
rm: remove write-protected regular empty file '/tmp/root_owned'? y
rm: cannot remove '/tmp/root_owned': Operation not permitted
$ echo $?
1
$ rm /tmp/nonexistent
rm: cannot remove '/tmp/nonexistent': No such file or directory
$ echo $?
1
On the other hand, groupadd(8) (at least) seems to have useful exit
codes. From the man page:
EXIT VALUES
The groupadd command exits with the following values:
0
success
2
invalid command syntax
3
invalid argument to option
4
GID is already used (when called without -o)
9
group name is already used
10
can't update group file
