The "type" shell builtin is a nice way to quickly identify
shell builtins in bash.

ecashin at meili:~$ uname
Linux
ecashin at meili:~$ which time
/usr/bin/time
ecashin at meili:~$ type time
time is a shell keyword
ecashin at meili:~$

Another hair-pulling builtin is "test", which can differ
from the /usr/bin/test or /bin/test in subtle ways.
