  # The example given recently with surrounding first char of the process
# name with [] is nearly correct. Additionally you have to enclose the
# command name in quotation marks! Try those both commands:
#
#	1. echo [m]y_command
#	2. echo "[m]ycommand"
#
# If you would like to kill a process by filtering ps output with grep,
# you could write the following. As mentioned: replace "[p]rocessname"
# with your own process it's name, surround first char with [] AND embed
# the whole process name in quotation marks.
kill -15 "$(ps ax | grep "[p]rocessname" | cut -d' ' -f1)"
