st - Man Page

simple terminal

Examples (TL;DR)


st [-aiv] [-c class] [-f font] [-g geometry] [-n name] [-o iofile] [-T title] [-t title] [-l line] [-w windowid] [[-e] command [arguments...]]

st [-aiv] [-c class] [-f font] [-g geometry] [-n name] [-o iofile] [-T title] [-t title] [-w windowid] -l line [stty_args...]


st is a simple terminal emulator.



disable alternate screens in terminal

-c class

defines the window class (default $TERM).

-f font

defines the font to use when st is run.

-g 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.

-n name

defines the window instance name (default $TERM).

-o iofile

writes all the I/O to iofile. This feature is useful when recording st sessions. A value of "-" means standard output.

-T title

defines the window title (default 'st').

-t title

defines the window title (default 'st').

-w windowid

embeds st within the window identified by windowid

-l 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). By default st initializes the serial line to 8 bits, no parity, 1 stop bit and a 38400 baud rate. The speed is set by appending it as last argument (e.g. 'st -l /dev/ttyS0 115200'). Arguments before the last one are stty(1) flags. If you want to set odd parity on 115200 baud use for example 'st -l /dev/ttyS0 parenb parodd 115200'. Set the number of bits by using for example 'st -l /dev/ttyS0 cs7 115200'. See stty(1) for more arguments and cases.


prints version information to stderr, then exits.

-e command [ arguments ... ]

st 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 the 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.

Ctrl-Print Screen

Toggle if st should print to the iofile.

Shift-Print Screen

Print the full screen to the iofile.

Print Screen

Print the selection to the iofile.

Ctrl-Shift-Page Up

Increase font size.

Ctrl-Shift-Page Down

Decrease font size.


Reset to default font size.

st can be customized by creating a custom config.h and (re)compiling the source code. This keeps it fast, secure and simple.
