NAME

       urxvtd - urxvt terminal daemon

SYNOPSIS

       urxvtd [-q|--quiet] [-o|--opendisplay] [-f|--fork] [-m|--mlock]

       urxvtd -q -o -f    # for .xsession use

DESCRIPTION

       This manpage describes the urxvtd daemon, which is the same vt102 terminal emulator as
       urxvt, but runs as a daemon that can open multiple terminal windows within the same
       process.

       You can run it from your X startup scripts, for example, although it is not dependent on a
       working DISPLAY and, in fact, can open windows on multiple X displays on the same time.

       Advantages of running a urxvt daemon include faster creation time for terminal windows and
       a lot of saved memory.

       The disadvantage is a possible impact on stability - if the main program crashes, all
       processes in the terminal windows are terminated. For example, as there is no way to
       cleanly react to abnormal connection closes, "xkill" and server resets/restarts will kill
       the urxvtd instance including all windows it has opened.

OPTIONS

       urxvtd currently understands a few options only. Bundling of options is not yet supported.

       -q, --quiet
           Normally, urxvtd outputs the message "rxvt-unicode daemon listening on <path>" after
           binding to its control socket. This option will suppress this message (errors and
           warnings will still be logged).

       -o, --opendisplay
           This forces urxvtd to open a connection to the current $DISPLAY and keep it open.

           This is useful if you want to bind an instance of urxvtd to the lifetime of a specific
           display/server. If the server does a reset, urxvtd will be killed automatically.

       -f, --fork
           This makes urxvtd fork after it has bound itself to its control socket.

       -m, --mlock
           This makes urxvtd call mlockall(2) on itself. This locks urxvtd in RAM and prevents it
           from being swapped out to disk, at the cost of consuming a lot more memory on most
           operating systems.

           Note: In order to use this feature, your system administrator must have set your
           user's RLIMIT_MEMLOCK to a size greater than or equal to the size of the urxvtd binary
           (or to unlimited). See /etc/security/limits.conf.

           Note 2: There is a known bug in glibc (possibly fixed in 2.8 and later versions) where
           calloc returns non-zeroed memory when mlockall is in effect. If you experience crashes
           or other odd behaviour while using --mlock, try it without it.

EXAMPLES

       This is a useful invocation of urxvtd in a .xsession-style script:

          urxvtd -q -f -o

       This waits till the control socket is available, opens the current display and forks into
       the background. When you log-out, the server is reset and urxvtd is killed.

ENVIRONMENT

       RXVT_SOCKET
           Both urxvtc and urxvtd use the environment variable RXVT_SOCKET to create a listening
           socket and to contact the urxvtd, respectively. If the variable is missing then
           $HOME/.urxvt/urxvtd-<nodename> is used.

       DISPLAY
           Only used when the "--opendisplay" option is specified. Must contain a valid X display
           name.
