I've switched back and forth between UNIX, VMS, MS/DOS, and other OSes. Others use DIR to do what ls does on UNIX. I wrote a script that saves me retyping a command and gives me a grin, too:
%dirHey! This is UNIX! Well, okay... but just this once... total 265 -rw-rw-r-- 1 ellie 47279 Dec 16 13:22 2edit.2 -rw-r--r-- 1 jerry 21802 Nov 12 18:24 7911.ps drwxrwsr-x 2 jerry 14848 Dec 24 07:17 RCS
| hey | The Bourne shell script, named hey, is simple. It prints its complaint to standard error so the message won't be redirected into a file or down a pipe. Then it tests the name you called it with (in this case, dir) and runs the command you've configured it to run instead (here, ls -l): |
|---|
$@ | case "$0" in
*dir) ls -l ${1+"$@"} ;;
*md) mkdir ${1+"$@"} ;;
...and so on...

You can give the single hey script file as many names as you want by making links (18.3) to it. Article 8.8 shows a similar setup with a different purpose.
