some cool shell scripts

This script will enhance the operation of standard UNIX commands by doing some simple checking of the command

line parameters and asking for user confirmation.

Copy a file

if [ "$#" != 2 ]

then

 print " Usage: copy from to"

 exit 1

fi

from="$1"

to="$2"

See if the destination file already exists

if [ -f "$to" ]

 print "$to already exists; overwrite (y/n)?\c"
