For example, sometimes I would like to run /bin/kill instead of the builtin kill. Is this best done as

env kill

or simply

/bin/kill

or perhaps something else?

回答1:

You seem to be looking the builtin enable. Saying enable -n kill would disable the builtin kill.

Say enable kill in order to enable it again.

The manual gives more information on Shell Builtin Commands.

回答2:

You want that a simple call to command kill should call /bin/kill & not the shell built-in.

There are 2 more options (in addition to what is specified by devnull's answer.):

You can alias kill to /bin/kill.

Or declare a function kill, which internally calls /bin/kill.
