|-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).|
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.|
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 users 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.
|-e, --eval perlstring||
Evaluate the given perl code after basic initialisation (requires perl
support to be enabled when compiling urxvtd).
This can be used for example to configure the internal perl interpreter, which is shared between all terminal instances, or create additional listening sockets for additional protocols.
The code is currently executed before creating the normal listening sockets: this might change in future versions.
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.
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.
