pkill

From Wikipedia, the free encyclopedia

pkill is a command line utility initially written for use with the Solaris 7 operating system. It has since been reimplemented for Linux and OpenBSD.

As with the kill and killall commands, pkill is used to send signals. The pkill command allows the use of extended regular expression patterns and other matching criteria.

Kill the most recent created acroread process
