forkbomb unknown A forkbomb (see related project descriptions) implemented as a single-line/13 characters Unix shell script. In other words: You just have to type these 13 characters (which superficially resemble smilies or ASCII art) on the command line/the terminal window of any computer running a Unix-like operating system:
:(){ :|:& };:
The original author of this forkbomb is unknown, although it appeared in usenet [1] and mailing list groups dating back to the late '90s [2], and a shorter version was published in early versions of the jargon file [3].
