zsh: correct 'sudo' to '_sudo' [nyae]?

zsh: correct 'sudo' to '_sudo' [nyae]?

[Hannu Koivisto]

Greetings,

I always get this message when I start a new shell (whether by
logging to a system or by saying "zsh" when I'm logged on) and try
to run sudo even though sudo is in path.  rehash doesn't help, but
"which sudo" always fixes the problem.  What could be the culprit?

zsh 4.0.4, HP-UX 11i.

It's not surprising that "rehash" doesn't help, as all that does is
empty the command hash table, and correction treats the contents of the
command hash table as the correct spellings.

Does "rehash -f" (both empty the command hash and refill it again) help?

Do you use the HASH_LIST_ALL option?  Unless that option is set, the
command hash table does not automatically fill itself during correction.

Ok, I tried it just because it has helped for the same problem when
I have installed new software.

No.

I don't use it but I tried setting it and it changed nothing.

OK, that means there can only be one other reason for this happening:
the directory containing `sudo' is not readable.  That is, it has execute
permission set so that by giving the full path to `sudo' you are allowed
to execute the file, but an `ls' on that directory would deny permission.

In this event, `which' searches for and adds to the hash table the single
command by full name, and therefore succeeds, whereas the spell checker
and `rehash -f' try to examine all names in the directory and therefore
fail.
