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
