What can affect whether a comamnd is found in PATH?

[Peng Yu]

Hi,

$ type -P cmd

I am trying to find a command using the above command. But it finds nothing.

Then I call the command with its abspath.

$ /abs/path/cmd

Then I can find the command. I also run `hash -r` before. But it didn't help.

$ type -P cmd
/abs/path/cmd

`type` is the following builtin.

$ type type
type is a shell builtin

This looks weird. Does anybody know how to debug this issue?

Can I exclude the possibility that this is caused by a bug in this
version of bash?

$ bash --version
