.Sh NAME
.Nm resizewin
.Nd update the kernel window size for the current TTY
.Sh DESCRIPTION
Query the terminal emulator window size with the
.Dv TIOCSWINSZ
ioctl and set the window size known by the kernel to the new values.
The terminal is assumed to be VT100/ANSI compatible.
.Nm
is functionally similar to
.Xr resize 1 ,
which is part of the
.Xr xterm 1
distribution.
However,
.Nm
only works with VT100/ANSI-compatible terminals and does
not emit commands to set environment variables.
.Pp
After a terminal window has been resized, running
.Nm
updates the kernel's window size to match the new size.
.Pp
Note that virtually all modern terninals support VT100/ANSI escape
sequences, including xterm, konsole, gnome-terminal iTerm,
Terminal.app, and puTTY.
.Sh SEE ALSO
.Xr resize 1 ,
.Xr stty 1
.Sh HISTORY
.Nm
appeared in FreeBSD 11.
