enables alternate screen, which is disabled by default, but is normally enabled in most terminals. It's the thing which prevents less, vi, etc. from clobbering the screen contents and leaving their gunk behind after exiting.
(A Google search seems to indicate that some people dislike this feature, but I found screen unusable until I discovered this option.)
Thank you! I have been using screen for 2 years and wanted to know how to fix this, but never knew what phrase to google to see if there was a fix. Every time I would background emacs (^z) it would clobber all of my previous console output so I would have to re-grep things, for example.
In return I give you my favorite screen hack that displays the available RAM on the server every 30 seconds in the caption:
The caption string above also prints the current window titles and the time/date, so this is also useful for keeping ssh sessions open indefinitely since there is activity at least once a minute when the time updates.
Here's the mandatory "if you're using GNU Screen check out tmux" comment.
Really though, check it out. The main thing I like better in tmux is that it does both horizontal and vertical split terminal windows in a way that seems much more intuitive to me than screen.
This is absolutely uncanny. I've just started writing a similar blog post thread about my dev environment, and its similar to yours (i.e. screen (I'm moving to tmux though), vim, bash, etc.).
I really wish there was a nice way to run nested screens, I like having screen run locally, but I always want to be able to easily attach and detach from screen sessions on my server. I know I can escape them with keyboard shortcuts, but its confusing and I have never managed to get used to it, so I generally do server screen sessions in a seperate terminal
I use backtick(`) as the meta key and that works till I'm 2 levels nested. I can do `+p or ``+p to go to the next screen window at the 1st or 2nd level this way. However, 3rd level doesn't work, unless I set a different meta key on the 3rd machine. Having some shortcut to select the current nesting level would be awesome :)
Thanks for a solution to the problem of missing bright/bold colors that I found in your .screenrc. This issue hadn't bothered me much, otherwise I'd have researched it before, but it's nice to have it fixed anyway.
