RT(1) General Commands Manual RT(1)

rt — a simple terminal

rt [-aiv] [-c class] [-f font] [-n name] [-o iofile] [-T title] [-t title] [-l line [stty_args]] [-w windowid] [-e command [arguments]]

rt is a simple terminal emulator. It is primarily designed to provide a minimal terminal for tmux(1) and therefore doesn't include many features.

disable alternate screens in terminal.
class
defines the window class (default $TERM).
font
defines the font to use when rt is run.
geometry
defines the X11 geometry string. The form is [=][<cols>{xX}<rows>][{+-}<xoffset>{+-}<yoffset>]. see XParseGeometry(3) for further details.
will fixate the position given with the -g option.
name
defines the window instance name (default $TERM).
title
defines the window title (default 'rt').
title
defines the window title (default 'rt').
windowid
embeds rt within the window identified by windowid.
line
use a tty line instead of a pseudo terminal. line should be a (pseudo-)serial device (e.g. /dev/ttyS0 on Linux for serial port 0). When this flag is given, remaining arguments are used as flags for stty(1). If you want to set odd parity on 115200 baud use for example 'rt -l /dev/ttyS0 parenb parodd 115200'. Set the number of bits by using for example 'rt -l /dev/ttyS0 cs7 115200'. See stty(1) for more arguments and cases.
prints version information to stderr, then exits.
command [arguments]
rt executes command instead of the shell. If this is used it must be the last option on the command line, as in xterm /rxvt. This option is only intended for compatibility, and all remaining arguments are used as a command even without it.

Send a break in the serial line. Break key is obtained in PC keyboards pressing at the same time control and pause.
Toggle if rt should print to the iofile.
Print the full screen to the iofile.
Print the selection to the iofile.
Increase font size.
Decrease font size.
Reset to default font size.
Paste from primary selection (middle mouse button).
Copy the selected test to the clipboard selection.
Paste from the clipboard selection.

rt can be customized either by creating a custom config.h and (re)compiling the source code, or via the .Xresources file using the 'rt.option: value' format. e.g.

rt.font: Monospace-12

The following config options are available

set the transparancy value.
set rt's font.
set rt's background color
set rt's foreground color
set color of cursor
set color of reverse cursor
where N is a number from 0 to 15. e.g. 'rt.color0: #161616'
terminal name (default 'rt-256color')
default '/bin/sh'
set minimum latency
set maximum latency
blinking timeout (set to 0 to disable blinking)
must be a value between -100 and 100. Set to 0 to disable bell
spaces per tab
border size in pixel
kerning/character bounding-box multipliers
kerning/character bounding-box multipliers
