Public bug reported:
If you have a non-executable file in the PATH, the "type" builtin will
show it, just like an executable file. However, "type -a" does not. Is
this expected behaviour, or is it a bug?
For example:
$ touch non-exec
$ PATH=.
$ type non-exec
non-exec is ./non-exec
$ type -a non-exec
bash: type: non-exec: not found
The manpage describes this behaviour, but it doesn't explain why it
exists. Personally, I would have expected "type" and "type -a" to behave
the same.
I stumbled on this while writing a Bash function that expands on "type",
providing info like whether a function is marked for export, executable
file type, etc, and this behaviour makes it difficult to parse "type
-at".
This occurs on 17.10 with Bash 4.4.12, though I'm running 14.04 with
Bash 4.3.11.
