No:
$ ../bash-4.3-patched/bash ./x25
4.3.22(16)-release
PATH = /usr/bin:/bin:/usr/local/bin
-rw------- 1 root wheel 14128 Jul 31 09:12 /usr/bin/echo
/bin/echo
-rwxr-xr-x 1 root wheel 14128 Apr 8 16:15 /bin/echo
$ cat ./x25
echo $BASH_VERSION
PATH=/usr/bin:/bin:/usr/local/bin
echo PATH = $PATH
ls -l /usr/bin/echo
type -P echo
ls -l $(type -P echo)
If you already have `echo' in the command hash table, type -P will return
