     The "which" command is not a good way to see how a command will
     be resolved. It is an external command (and at least one version
     will not work with bash), and it doesn't know about shell
     functions or aliases.

     The command to use is 'type'. With the -a option, it will tell
     you all of the possible commands that use the name. If you have a
     command, a function and an alias with the same name, it will list
     all three.
