# simplifies communication with dtach by removing options i don't use,
# settings nice defaults i can use and automate socket creation
# it takes the following args
# -h -- list usage, can also be show by just invoking dm
# -l -- lists sockets by reading all folders inside /tmp/dtach
# -d -- deletes a socket, used to remove dead sockets that weren't removed
# <alias> -- name that will be show in dm -l
# [command] -- name of the program, this is only necessary in the first time
# in the following times it will read /tmp/$NAME-socket and will open in the
# correct application, like << dm mail mutt >> then << ctrl-z >> , then typ
# ing << dm mail >> will open mutt anways
