resize  - set environment and terminal settings to current xterm window


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


   Resize prints a shell command for setting the  appropriate  environment
   variables  to  indicate the current size of xterm window from which the
   command is run.

   Resize determines the command through several steps:

   *   first, it finds the name of the user's shell program.  It uses  the
       SHELL  variable  if  set,  otherwise  it  uses the user's data from

   *   then it decides whether to  use  Bourne  shell  syntax  or  C-Shell
       syntax.   It  uses  a  built-in table of known shells, which can be
       overridden by the -u and -c options.

   *   then resize asks the operating system for  the  terminal  settings.
       This is the same information which can be manipulated using stty.

   *   then   resize  asks  the  terminal  for  its  size  in  characters.
       Depending on whether  the  "-s  option  is  given,  resize  uses  a
       different escape sequence to ask for this information.

   *   at  this  point, resize attempts to update the terminal settings to
       reflect the terminal window's size in pixels:

       *   if the -s option is used, resize then asks the terminal for its
           size in pixels.

       *   otherwise, resize asks the operating system for the information
           and updates that after ensuring that  the  window's  dimensions
           are a multiple of the character height and width.

       *   in  either case, the updated terminal settings are done using a
           different system call than used for stty.

   *   then resize updates the terminal settings to  reflect  any  altered
       values  such  as  its  size  in  rows or columns.  This affects the
       values shown by stty.

   *   finally,  resize  writes  the  shell  command   for   setting   the
       environment variables to the standard output.


   For  resize's 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 then read it back in with the "." command:

           $  resize > /tmp/out
           $  . /tmp/out


   The following options may be used with resize:

   -c      This option indicates that C shell commands should be generated
           even if the user's current shell is not /bin/csh.

   -s [rows columns]
           This option indicates that Sun console escape sequences will be
           used  instead  of  the VT100-style xterm escape codes.  If rows
           and columns are given, resize will  ask  the  xterm  to  resize
           itself using those values.

           Both  of  the  escape  sequences used for this option (first to
           obtain the window size and second to modify it) are subject  to
           xterm's  allowWindowOps  resource  setting.  The window manager
           may also choose to disallow the change.

           The VT100-style escape sequence used to  determine  the  screen
           size  always works for VT100-compatible terminals.  VT100s have
           no corresponding way to modify the screensize.

   -u      This option indicates that  Bourne  shell  commands  should  be
           generated even if the user's current shell is not /bin/sh.

   -v      This  causes  resize  to print a version number to the standard
           output, and then exit.

   Note that the Sun console escape sequences are  recognized  by  XFree86
   xterm  and  by dtterm.  The resize program may be installed as sunsize,
   which causes makes it assume the -s option.

   The rows and columns  arguments  must  appear  last;  though  they  are
   normally associated with the -s option, they are parsed separately.


   /etc/termcap   for the base termcap entry to modify.

   ~/.cshrc       user's alias for the command.


   SHELL          Resize  determines  the  user's  current  shell by first
                  checking if $SHELL is set, and using that.  Otherwise it
                  determines  the  user's shell by looking in the password
                  file  (/etc/passwd).   Generally  Bourne-shell  variants
                  (including  ksh) do not modify $SHELL, so it is possible
                  for resize to be confused if  one  runs  resize  from  a
                  Bourne shell spawned from a C shell.

   TERM           Resize sets this to "xterm" if not already set.

   TERMCAP        Resize  sets  this  variable  on  systems using termcap,
                  e.g., when resize is linked  with  the  termcap  library
                  rather  than  a  terminfo  library.  The latter does not
                  provide the complete text for a termcap entry.

   COLUMNS, LINES Resize sets these variables on systems  using  terminfo.
                  Many  applications  (including  the  curses library) use
                  those variables when set to override their screensize.
