Commands tagged screen

this bash command sets it so that when you type "screen ", it searches your running screens, and present valid auto-complete choices. The output is .

Note: You must have programmable completion enabled. Check with "shopt progcomp", set with "shopt -s progcomp"

There is no need to use the shell or construct. Screen offers varius ways of detaching and reattaching. man screen and look for -[rRdD].

to create a named session: sdr moo

hide:

resume: sdr moo

Tries to reattach to screen, if it's not available, creates one.

created an alias "irc" for it, since sometimes i forget if there already is a screen session running with irssi, this way I avoid creating a new one by mistake.

Use as: $ s host1

Will ssh to remote host upon first invocation. Then use C-a d to detatch. Running "s host1" again will resume the shell session on the remote host. Only useful in LAN environment. You'd want to start the screen on the remote host over a WAN.

Adapted from Hack 34 in Linux Server Hacks 2nd Addition.

This command attempts to attach to existing irssi session, if one exists, otherwise creates one.

I use "irc" because I use different irc clients depending on what system I am working on. Consistency is queen.

Starts a detached screen with the given screen-name.

Can be useful for automatic started scripts and init.d-scripts.

. a Ruby SSH helper script

. reads a JSON config file to read host, FQDN, user, port, tunnel options

. changes OSX Terminal profiles based on host 'type'

USAGE:

put 'ash' ruby script in your PATH

modify and copy ashrc-dist to ~/.ashrc

configure OSX Terminal profiles, such as "webserver", "development", etc

run "ash myhostname" and away you go!

v.2 will re-attach to a 'screen' named in your ~/.ashrc

Errors in output don't matter. Stop recording: ctrl-c. Result playable with Flash too.

IMPORTANT: Find a Pulse Audio device to capture from: pactl list | grep -A2 'Source #' | grep 'Name: ' | cut -d" " -f2

run it inside a screen session, you send commands to screen itself!

Use the command to create a script and bind it to a key using keyboard shortcut.

eg:

Script locks the screen in a loop until the command is executed again.At first it

Normally, if you su to another user from root and try to resume that other user's screen session, you will get an error like "Cannot open your terminal '/dev/pts/0' - please check." This is because the other user doesn't have permission for root's pty. You can get around this by running a "script" session as the new user, before trying to resume the screen session. Note you will have to execute each of the three commands separately, not all on the same line as shown here.

Configures screen to always display the clock in the last line (has to be configured only once).

After that you not only have got the possibility to detach sessions and run them in background, but also have got a nice clock permanently on your screen.

Bash alias for easy irssi within screen, attempts to attach to existing irssi session, if one exists, otherwise creates one - Including wipe for when system reboots and leaves "dead" session.

Grabs the cmdline used to execute the process, and the environment that the process is being run under. This is much different than the 'env' command, which only lists the environment for the shell. This is very useful (to me at least) to debug various processes on my server. For example, this lets me see the environment that my apache, mysqld, bind, and other server processes have.

Here's a function I use:

From my .bash_profile at http://www.askapache.com/linux-unix/bash_profile-functions-advanced-shell.html

In exemple, screen can bind keys to switch between windows. I like to use Ctrl + Arrow to move left or right window. So I bind like this in .screenrc :

bindkey ^[OD prev # Ctl-left, prev window

bindkey ^[OC next # Ctl-right, next window

Kills all windows in a gnu screen session and terminates it , on pressing Control-f , useful in closing screen session with large number of windows . Add it to your screenrc .

Use GNU/screen as a terminal emulator for anything serial console related.

screen /dev/tty

eg.

screen /dev/ttyS0 9600

By default, screen tries to restore its old window sizes when attaching to resizable terminals. This command is the command-line equivalent to typing ^A F to fit an open screen session to the window.

When you start screen as `ssh-agent screen`, agent will die after detatch.

If you don't want to take care about files when stored agent's pid/socket/etc, you have to use this command.

i spent way too many hours trying to fiddle with /etc/X11/xorg.conf trying to hook up various external projectors. too bad i didn't know this would solve all my problems.

Only useful for really flakey connections (but im stuck with one for now). Though if youre in this situation ive found this to be a good way to run autossh and it does a pretty good job of detecting when the session is down and restarting. Combined with the -t and screen commands this pops you back into your working session lickety split w/ as few headaches as possible.

And if autossh is a bit slow at detecting the downed ssh connection, just run this in another tab/terminal window to notify autossh that it should drop it and start over. Basically for when polling is too slow.

kill -SIGUSR1 `pgrep autossh`

Add this to your $HOME/.bashrc file. It will only set this prompt if it is running inside screen ($WINDOW var is set)

Looks like this...

Directly attach a remote screen session (saves a useless parent bash process)
