RESIZEWIN(1) FreeBSD General Commands Manual RESIZEWIN(1)
NAME
resizewin - update terminal size
SYNOPSIS
resizewin [-z]
DESCRIPTION
The resizewin utility queries the terminal emulator for the current
window size and updates the size known to the kernel using the TIOCSWINSZ
ioctl.
The following options are available:
-z
Do nothing unless the current kernel terminal size is zero. This is
useful when run from a user's profile (shell startup) scripts:
querying the window size is required for serial lines, but not when
logging in over the network, as protocols like TELNET or SSH already
handle the terminal size by themselves.
After a terminal window has been resized, running resizewin updates the
kernel's window size to match the new size.
resizewin is functionally similar to resize(1), which is part of the
xterm(1) (ports/x11/xterm) distribution. However, resizewin only works
with VT100/ANSI-compatible terminals and does not emit commands to set
environment variables.
The terminal is assumed to be VT100/ANSI compatible. The VT100/ANSI
escape sequences are supported by virtually all modern terminals,
including xterm, konsole, gnome-terminal, iTerm, Terminal.app, and PuTTY.
