In bash, the default when outputting to stdout is to wrap any lines wider than the console display. Is there a way to suppress this? During script execution, I want certain lines to be overwritten. This can be accomplished with the /r escape sequence rather than /n, but if the line is longer than the width of the display, it will still scroll the display.
On a related note, bash doesn't seem to be setting the $COLUMNS variable correctly in a sub-shell. At the console, the $COLUMNS variable contains the correct terminal width. If I change the terminal width, the $COLUMNS variable updates accordingly. If I run a bash script, however, this feature no longer works. The $COLUMNS variable remains null no matter what I try: killall -28 VDifferential shopt -s checkwinsize Neither works. I checked, and the checkwinsize option is enabled, but the $COLUMNS variable remains null even if I re-size the window. This is in a bash window in KDE4 under Debian Squeeze. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
