Automatically start sessions at system start
To start the saved screen sessions at system start, start crontab via:
crontab -e
and add the script screen-auto-start:
@reboot /full/path/to/screen-auto-start
The script screen-auto-start is part of this repository.
Automatically save all my session
I save my sessions manually, but here is a script to save your sessions periodically:
To start the saved screen sessions at system start, start crontab via:
crontab -e
and add the script screen-save-all-sessions to save all my sessions every day at 3:00am:
0 3 * * * /full/path/to/screen-save-all-sessions
The script screen-save-all-sessions is part of this repository.
Remove a saved session
Just remove the saved screenrc file:
rm ~/.screenrc-{SESSIONNAME}
Installation
Alternatives:
- Use my tool link-script-paths.
Or do it manually:
-
Close this repository and add it to the path environment.
-
Copy all scripts to a directory already added to the path environment. E.g.
/usr/local/bin
Limitations
- Screen Version 4.01 is needed, to support queried commands.
- Does not work on macOS, because there is no /proc filesystem. (Maybe with procfs on MacFUSE)
- Changing the number of a window is not supported. The window number is read from the environment, which can not be updated by screen.
- Saving window layouts is not jet implemented.
