CTRL-D ANOTHER USE

Many Unix Admins use the C shell as their interactive shell.
An often used feature of Csh is file completion - initiated
with 'set filec'. It allows the Csh user to type in partial
file names, and then press escape to get them completed where
possible. A little known side effect of this is that
Control-D (^D) will now generate file listings in the middle of
command lines.

Example 1: (where @ is a space)
host > @^D
Lists the current directory

Example 2:
host >ln -s /usr/^D
Lists the /usr directory

host >tar cvf /dev/nrtape /usr/m^D
Lists all m* files in the /usr directory

In each case, after the listing, you get a new command line and are
placed at the last point of edit.

Very handy if you you know what you wanted to do but forgot what you
wanted to do it with!
