Patch Level: 9
Release Status: release
Description:
"type -p CMD" normally has a non-zero return status if CMD is not
found. But if CMD is an alias, the return status is zero even though
nothing is printed to stdout.
Repeat-By:
$ type -p fred; echo $?
1
$ alias fred=
$ type -p fred; echo $?
0
- type -p return status is 0 if alias found,
