[bash] directories hide executables

[johndrinkwater]

A dir with the same name as a command "hides" the executable, example:

/boot/apps>ls -lah | grep sp drwxr-xr-x 1 baron users 2.0K 2006-05-07 12:09 spybmessage

/boot/apps>which spybmessage /boot/home/config/bin/spybmessage

/boot/apps>spybmessage sh: /boot/home/config/bin/spybmessage: Invalid Argument

/boot/apps>mv spybmessage spybmessageMoved

/boot/apps>spybmessage usage: /boot/home/config/bin/spybmessage app [args...]

fixed in revision 17372. Though the current PATH isn't used for the search, it should be another bug I think.
