resize

resize(1X)																resize(1X)

NAME

       resize - set TERMCAP and terminal settings to current xterm window size

SYNOPSIS

       resize [-u] [-c] [-s[row col]]

OPTIONS

       The following options may be used with resize: This option indicates that Bourne shell commands should be generated even if the user's cur-
       rent shell is not /bin/sh.  This option indicates that C shell commands should be generated  even  if  the  user's  current  shell  is  not
       /bin/csh.  This option indicates that Sun console escape sequences will be used instead of the special xterm escape code.  If rows and col-
       umns are given, resize will ask the xterm to resize itself.  However, the window manager may choose to disallow the change.

DESCRIPTION

       The resize command prints a shell command for setting the TERM and TERMCAP environment variables to indicate the current size of xterm win-
       dow  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
	       %  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 do not have command functions will need to send the output to a tem-
       porary file and the read it back in with the "." command:
	       $  resize > /tmp/out
	       $  . /tmp/out

FILES

       for the base termcap entry to modify.  user's alias for the command.

BUGS

       The -u or -c must appear to the left of -s if both are specified.
