screen

Make the xterm title work with PROMPT_COMMAND

Change “xterm*)” to “xterm*|screen*)” in /etc/bashrc for the PROMPT_COMMAND check

Modify the PS1 prompt to '\[<esc>k<esc>\\]\W >'. <esc> is created with Ctrl+V, ESC and after the 2nd <esc> a '\' must follow. '\W' is the variable name for the current directory. (e.g. PS1=“\[^[k^[\\\\\]\W > ” in /etc/bashrc)
Add the line: shelltitle '> |bash' to .screenrc
Add the line: hardstatus string ”[%n %t] %h” to .screenrc

To allow another user to view your screen:

$ :multiuser on
$ :acladd USERNAME
$ :aclchg USERNAME [+-r][+-w][+-x] "#?"
$ :acldel USERNAME

If you want to grant read-only permissions do:

$ :multiuser on
$ :acladd USERNAME
$ :aclchg USERNAME -wx] "#?"

To view another users screen, /usr/bin/screen must have suid root permissions.

sudo chmod +s /usr/bin/screen
sudo chmod 755 /var/run/screen

If that is done, you can open the session by

screen -r USER/PID.TTY.HOSTNAME

$ screen -p <TERMINALNAME> -X stuff "blah^M";
