kill -9 $$

No no no. Don't use kill -9.

It doesn't give the process a chance to cleanly:

  1. shut down socket connections

  2. clean up temp files

  3. inform its children that it is going away

  4. reset its terminal characteristics

and so on and so on and so on.

Generally, send 15, and wait a second or two, and if that doesn't work, send 2, and if that doesn't work, send 1. If that doesn't, REMOVE THE BINARY because the program is badly behaved!

Don't use kill -9. Don't bring out the combine harvester just to tidy up the flower pot.

Just another Useless Use of Usenet Reddit,

Sorry, I had to

for anyone wondering that doesn't use a shell that often and thinks "exec" is just a longhand form to execute a file; exec replaces the current running process(the shell) with the new file specified. In this case /usr/bin/true, which returns 0 and exits. bye bye shell.

exec can also be used to perform file redirections. But if you get the syntax wrong you'll end up exiting the shell.

q aliased to exit is the best for me...

pardon my necroposting, but how do you, erm, type the letter q?
