I vaguely recall that typing 'copy con clock$' would freeze a computer.
On DOS you could also have fun by replacing prompt $p$g with prompt {whatever text you want instead of c:}
Righto :)
I was a DOS 'programmer' long before I migrated to Linux - the same way some guy who used to write bat files with environment variables and errorlevel commands might migrate to a shell script.
What I really wanted was to be able to embed ^g into the Linux command line prompt, but so far I haven't been able to. On DOS I could add ^g (the Bell character) to the prompt so each time a command finished it beeped.
On old unix systems, you could rename /dev/null and symlink /dev/audio to /dev/null...
Then you just had to wait.
