These are some common commands I use. In the examples,
C-a means push the Control + A buttons at the same time.
Send command to all windows
Enter command line mode with
:. This will send
ls -l to all windows:
at "#" stuff "ls -l^M"
Automatic window naming
When I connect to hosts with SSH I like to have the window names set automatically to the hostname of the server I am connected to. This can be done with a simple SSH local command.
- Edit your SSH client configuration file,
~/.ssh/config. A host definition needs to be added along with the local command to execute. In this case I apply this local command to all hosts I connect to, so the content is like this:
# Set default options for all other sessions Host * # Default user = root unless you specify a username when connecting or in a seperate host definition User root # Run local command to set the screen window name to the hostname of the server that you are connecting to LocalCommand ~/.ssh-hostname %h # Turn on compression Compression yes
- Create the file
~/.ssh-hostname. This will be executed when connecting to hosts and it is what will set the window name. The content of the file needs to be set to this:
#!/bin/bash echo -ne "\033k$1\033\\"
- Make the file created in step to executable:
chmod +x ~/.ssh-hostname
Attempt to SSH to a host when using screen to verify it works.
