NAME
resize - set TERMCAP and terminal settings to current xterm window size
SYNOPSIS
resize [ -u | -c ] [ -s [ row col ] ]
DESCRIPTION
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
OPTIONS
The following options may be used with resize:
- -u
- This option indicates that Bourne shell commands should be generated even if the user's current shell isn't /bin/sh.
- -c
- This option indicates that C shell commands should be generated even if the user's current shell isn't /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. However, the window manager may choose to disallow the change.
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.
FILES
- /etc/termcap
- for the base termcap entry to modify.
- ~/.cshrc
- user's alias for the command.
