Scroll is a program that stores all the lines of its child and be used in st as a way of implementing scrollback. This solution is much better than implementing the scrollback in st itself because having a different program allows to use it in any other program without doing modifications to those programs.

.SH DESCRIPTION
|
|
.B st
|
|
is a simple terminal emulator.
|
|
.SH OPTIONS
|
|
.TP
|
|
.B \-a
|
|
disable alternate screens in terminal
|
|
.TP
|
|
.BI \-c " class"
|
|
defines the window class (default $TERM).
|
|
.TP
|
|
.BI \-f " font"
|
|
defines the
|
|
.I font
|
|
to use when st is run.
|
|
.TP
|
|
.BI \-g " geometry"
|
|
defines the X11 geometry string.
|
|
The form is [=][<cols>{xX}<rows>][{+-}<xoffset>{+-}<yoffset>]. See
|
|
.BR XParseGeometry (3)
|
|
for further details.
|
|
.TP
|
|
.B \-i
|
|
will fixate the position given with the -g option.
|
|
.TP
|
|
.BI \-n " name"
|
|
defines the window instance name (default $TERM).
|
|
.TP
|
|
.BI \-o " iofile"
|
|
writes all the I/O to
|
|
.I iofile.
|
|
This feature is useful when recording st sessions. A value of "-" means
|
|
standard output.
|
|
.TP
|
|
.BI \-T " title"
|
|
defines the window title (default 'st').
|
|
.TP
|
|
.BI \-t " title"
|
|
defines the window title (default 'st').
|
|
.TP
|
|
.BI \-w " windowid"
|
|
embeds st within the window identified by
|
|
.I windowid
|
|
.TP
|
|
.BI \-l " line"
|
|
use a tty
|
|
.I line
|
|
instead of a pseudo terminal.
|
|
.I 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
|
|
.BR 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
|
|
.BR 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
|
|
.BR stty(1)
|
|
for more arguments and cases.
|
|
.TP
|
|
.B \-v
|
|
prints version information to stderr, then exits.
|
|
.TP
|
|
.BI \-e " command " [ " arguments " "... ]"
|
|
st executes
|
|
.I command
|
|
instead of the shell. If this is used it
|
|
.B 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.
|
|
.SH SHORTCUTS
