# You know that really annoying message that pops up...

# Mosh: You have 3 detached Mosh sessions on this server, with PIDs:
#        - mosh [2294539]
#        - mosh [1874313]
#        - mosh [2294805]

# I often find myself copying this list of PIDs in order to kill them manually
# ... so this script was born.  Maybe others will find it useful.
