Resize
prints a shell command for setting the TERM and TERMCAP environment variables
to indicate the current size of xterm window from which the command
is run. For this output to take effect, resize must either be evaluated
as part of the command line (usually done with a shell alias or function) or
else redirected to a file which can then be read in. From the C shell (usually
known as /bin/csh), the following alias could be defined in the
user's .cshrc:
% alias rs 'set noglob; eval `resize`'
After resizing the window, the user would type:
% rs
Users of versions of the Bourne shell (usually known as /bin/sh) that
don't have command
functions will need to send the output to a temporary file and the read it back
in with the ``.'' command:
$ resize > /tmp/out
$ . /tmp/out
