set TERMCAP and terminal settings to current xterm window size 



resize [-c | -u]


The resize utility generates and displays a shell command for setting the TERM and TERMCAP environment variables to indicate the current size of the 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 (csh), the following alias could be defined in the user's .cshrc:

alias rs 'set noglob; eval `resize -c`'

After resizing the window, the user would type:


The exact command generated by resize depends upon the current setting of the SHELL environment variable. If SHELL indicates a Korn or Bourne-Again shell (such as sh, ksh, or bash), resize generates a sh-compatible command. If SHELL indicates a C Shell (such as csh), resize generates a csh-compatible command.

If you run the resize command from the Windows command interpreter, you will need to send the output (a sh-compatible command) to a temporary file and then read it back in with sh:

resize > $TMPDIR/out
sh $TMPDIR/out



generates csh-compatible commands regardless of the setting of SHELL.
