# hey - script that complains about commands from other operating systems,
# then runs the UNIX equivalent.
#
# Link this to whatever command names you want to complain about,
# and put the links in some directory ahead of the original command.
#
# For example, if you (or other people) keep typing "dir" on UNIX
# when they mean "ls", link this script to be named "dir"; it will
# enable the first case below:

# Write snide comments to stderr so they won't mess up redirection:
echo "Hey!  This is UNIX!  Well, okay... but just this once..." 1>&2

# To add new commands, add the new name with a * before it at left.
# Then add command you want to run instead.
# The ${1+"$@"} is a portable way to insert command-line arguments;
# if the command doesn't need command-line arguments, don't add it:
case "$0" in
*dir)	ls -l ${1+"$@"} ;;
*md)	mkdir ${1+"$@"} ;;
*)	echo "Error in 'hey' script setup... shouldn't get here!" 1>&2
	exit 1
