Hi,
My machine just bombed when I did the following stupid command.
:(){:|:};:
Zsh chewed up everything on the machine...
I ran it knowing I'd probably have to reboot.
But, I hardly expected it to panic.
Or, was that normal?
Anyway, the following is some detail...
Please mail me if there is more I'm ment to do.
Thanks in advance :)
