-- Submitted by James Devenish (j-devenish@users.sourceforge.net) Modified by danh@ Proctools provides the pgrep and pkill commands which can scan for and send signals to processes that are matched by command-line options. The pgrep utility displays process IDs for those processes that match the requirements specified on the command line. The pkill utility sends a signal to process IDs for those processes that match the requirements specified on the com- mand line. WWW: http://sourceforge.net/projects/proctools
