Hi,
I use a shell script to manage my various screen sessions.
It uses dialog to display the screens on the current machine
and lets me choose the screen to attach to. I thought it will
be useful to others too.
You need to put this somewhere on your machine and add a
line to the end of your ~/.bash_profile to execute this. For
example, this is what I have on the last line of my .bash_profile
. $HOME/bin/choosescreen.sh
With regards,
Gomu.
#!/bin/sh
#
# Screen chooser
#
# To activate this, put this file in your home directory and add
# . , $HOME/choosescreen.sh
# at the end of the .bash_profile in your home directory.
#
# If you have any questions, ask [EMAIL PROTECTED]
#========== Configurable parameters ====================
# Seconds to wait before defaulting to no screens mode

# Instructions to detach and quit are displayed at the title bar in novice mode
