Can anyone tell me how to find out what the width of a bash terminal window (such as a xterm) in a shell (well tcl) script? This would be really helpful for me!

Using bash you could use COLUMNS.

$ echo $COLUMNS will return the width of the terminal.

I'm not a TCL user so I don't know if there is a simular option. I do know enough to know that you can use linux/unix commands inside TCL.

Hope this helps.

Yeah, and columns too. But.. they must be exported so...

Code:

sh % export LINES COLUMNS

sh % tclsh
% puts $env(LINES)
