Basically like some of my own that I've posted below. I'm looking for added functionality to the programme 'screen'. At the very least have a look at the last line for a fantastic 'menu bar' at the bottom of a screen session.

I also can't live without the menu bar. One thing I do not like putting on the menu which a lot of people have is the time; it prevents PuTTY's scroll back from staying scrolled back (since it's considered a screen update)
Murali Suriar : You could use screen's inbuilt scrollback? `C-A [` by default will put you into copy mode, and will allow you to navigate your current tab using keyboard commands like a text editor?From Mikeage -
I also use a fairly involved caption/hardstatus line combination, to simulate the effect of dropdown tabs (the caption line is solid grey and the current tab in the hardstatus is the same color).
I also have my shell tell screen what the current process name is and what directory I'm in, so my tab names stay up to date with what I'm doing in each tab. This is critical to remembering what I'm doing where without having to flick through all my open tabs.
# don't use the hardstatus line for system messages, use reverse video instead # (we'll be using it for the list of tab windows - see hardstatus alwayslastline # below) hardstatus off # use the caption line for the computer name, load, hstatus (as set by zsh), & time # the caption line gets repeated for each window being displayed (using :split), # so we'll use color cues to differentiate the caption of the current, active # window, and the others. # always - display the caption continuously.

The most useful screen customization, IMHO, is to change the modifier key to something other than C-a. That is just too important of a key to have eaten (go to the beginning of the line at all readline prompts, and in emacs). I use C-z, since I need to suspend applications a lot less often than I need to edit something at the beginning of the line.
The magic word is:
escape ^zaCraig Sanders : i set mine to ctrl-K because it's the least commonly used ctrl key in the apps that i use. ^A is too useful in bash/readline to sacrifice.Hamish Downer : To check what you clash with you could consult http://superuser.com/questions/120333/what-are-the-common-control-combinations-in-a-terminal-setting (which I asked with this in mind).From jrockway -
For those wanting a less cryptic way of getting a nice screen set up, I can heartily recommend byobu (formerly called screen profiles). It gives you a nice default set of stuff at the bottom of the screen - the bottom line contains various handy status information, and the second from bottom line contains a list of your screen windows. All this can be configured in a nice easy ncurses menu by pressing F9.
The function keys are mapped to common operations:
- F2 - create a new window
- F3 - Go to the prev window
- F4 - Go to the next window
- F5 - Reload profile
- F6 - Detach from the session
- F7 - Enter scrollback mode
- F8 - View all keybindings
- F9 - Configure screen-profiles
- F12 - Lock this terminal
See this article for a tutorial and screenshots.
Byobu is in the ubuntu repositories from karmic (9.10) onwards. In jaunty it was called screen-profiles. Before that it can be installed from this ppa of from this download page. It's widely packaged for other up-to-date distros aswell.
It does depend on python, but once you have byobu set up as you like it, you can have it generate a tar ball containing all you need to recreate your screen on another computer using byobu-export.
jtimberman : Screen-profiles is *awesome*. I was going to answer with the same.From Hamish Downer -
I often have more than 10 windows running and wanted a way to select them. I found out how to configure C-a Shift+0 through 9 to select windows 10 through 19.
bind ! select 11 bind @ select 12 bind \# select 13 bind $ select 14 bind % select 15 bind \^ select 16 bind & select 17 bind * select 18 bind ( select 19 bind ) select 10Note the escapes on # and ^.

The backtick command is pretty groovy. Read about it in man screen. I use it like so:
backtick 1 15 15 $HOME/bin/cpuusage # now add '%1`%% CPU' to your hardstatus string. Result is like 38.4% CPU.My cpuusage script for Linux and Mac is:
#!/bin/bash if [[ $(uname) == "Darwin" ]]; then top -i1 -l2 -n0|awk '/CPU/{i+=1; gsub(/%/,"",$0);p=substr(sprintf("%3.2f",$8+$10),0,4);if(i==2){printf "%g", p}}' else awk 'NR==1 {p=substr(sprintf("%3.2f", ($2+$3)/($2+$3+$4+$5)*100),0,4); printf "%g", p;}'</proc/stat fiFrom Richard Bronosky -
I have F11 and F12 set to cycle through windows, makes it quicker to move between windows, especially for windows > 10
# Bind F11 and F12 (NOT F1 and F2) to previous and next screen window bindkey -k F1 prev bindkey -k F2 nextFrom theotherreceive -
If you are using urxvt, the following will allow CTRL+LEFT and CTRL+RIGHT to be used to move to the previous and next tab window:
bindkey "^[Od" prev # ctrl-left bindkey "^[Oc" next # ctrl-rightReconnecting to a remote screen session that should always be running or immediately created:
bind V screen -t MYTABNAME ssh -t MYUSERNAME "screen -x main || screen -R -S main"Turning flow control off by default allows you to use CTRL+R in rtorrent properly:
defflow offIf running rtorrent as a daemon with its own user account, this .screenrc can be useful:
vbell off startup_message off escape ^Rr screen -t rtorrent rtorrent multiuser on acladd YOURUSERNAME defflow offFrom Trey
