abduco - terminal session manager

abduco provides a way to disconnect a given application from its controlling terminal,
thus it provides roughly the same session attach/detach support as screen(1), tmux(1) or

If the command to execute is not specified, the environment variable $ABDUCO_CMD is
examined, if it is not set dvtm(1) is executed.

By default all session related information is stored in $HOME/.abduco with $TMPDIR/.abduco
as a fallback and /tmp/.abduco as a last resort.

However if a given session name represents either a relative or absolute path it is used

If for some reason the unix(7) domain socket representing a session is deleted, sending
SIGUSR1 to the server process will recreate it.


If no command line arguments are given all currently active sessions are printed sorted by
their respective creation date. Lines starting with an asterik * indicate that at least
one client is connected. A plus sign + indicates that the command terminated while no
client was connected, attach to get its exit status.

-v Print version information to standard output and exit.

-r Readonly session, i.e. user input is ignored.

-e detachkey
Set the key to detach which by default is set to CTRL+\ i.e. ^\ to detachkey.

-c Create a new session and attach immediately to it.

-n Create a new session but do not attach to it.

-A Try to connect to an existing session, upon failure create said session and attach
immediately to it.

-a Attach to an existing session.


Start a new session (assuming dvtm(1) is in $PATH) with

abduco -c my-session

do some work, then detach by pressing CTRL+\ and later reattach with

abduco -a my-session
