Not a good idea, but maybe you have a reason to do that (homework?). You may have a look at "escape character" in man bash or in your reference text.

Escape it.

launch gedit
save a file as $SHELL
open up nautilus/Konquerer
right click on file and press send to trash

check rm command there is similar example: linux commands

On the commandline try:
% rm -- '$SHELL'

usually, the argument -- tells a program that after that, even if something happens to start with a -, it is not a program argument anymore, i.e.:

% rm -- -f

merijnv · 11-06-2007, 09:35 AM

ow, and to create such a file:

% touch '$SHELL'

Code:

touch \$SHELL
rm \$SHELL

Usually at school they ask you to remove -file but this one is even more funny, I hope it's asked to be run as root

Much more dangerous example:

Code:

touch -- '-f *'
rm -i -- '-f *'

The -i option on rm can save you from serious mistakes

However the -f option overrides the -i option!
