 |
|
For a nice status bar at the bottom of every screen session:
| Code: | /etc/screenrc
+++ hardstatus alwayslastline "[ %c ][ %-w%{= KW}%50>%n \0337\033]2;%t\007\0338%t%{-}%+w%< ]" # if you just want terminal title updated
OR
+++ hardstatus alwayslastline "[ %c ][ %-w%{= KW}%50>%n \0337\033]2;%t\007\033k%t\033\\\0338%t%{-}%+w%< ]" # if you want both terminal title and parent screen window title updated when nesting screens
/etc/bash/bashrc
+++ # for screen
+++ if [[ ${EUID} == 0 ]] ; then
+++ PS1="\[\0337\033]2;\h\007\033k\h\033\134\0338\]$PS1"
+++ else
+++ PS1="\[\0337\033]2;\u@\h\007\033k\u@\h\033\134\0338\]$PS1"
+++ fi |
Note that screen doesn't have any equivalent to bash's \[ and \] so you get a space at the end of the bar equal to the width of the title(s).
And to start/resume screen sessions at every login (NOT for root accounts):
| Code: | ~/.bash_profile, /etc/skel/.bash_profile:
# /etc/skel/.bash_profile:
# $Header: /home/cvsroot/gentoo-src/rc-scripts/etc/skel/.bash_profile,v 1.10 2002/11/18 19:39:22 azarah Exp $
+++ # either use the line below, or set each user's shell to /usr/bin/screen.
+++ # this is a TERRIBLE idea to apply to root accounts.
+++ exec screen -RR -s /bin/bash
+++ # or exec screen -xRR -s /bin/bash to always attach to the same session, even if multiple ssh sessions are opened simultaneously (same as setting shell to /usr/bin/screen)
+++
# the exec above stops this from occurring, leave it in as a fall-through though
#This file is sourced by bash when you log in interactively.
[ -f ~/.bashrc ] && . ~/.bashrc |
The bar looks like this with nested screens:
