NAME
resizewin
—
update terminal size
SYNOPSIS
resizewin |
[-z ] |
DESCRIPTION
Theresizewin
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) 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.
