Cannot make directory '/run/screen': Permission denied

solve problem

Q:
when I open screen in my linux Ubuntu, result in output the words Cannot make directory '/run/screen': Permission denied.

A:

he directory /run/screen is the socket directory for screen.

Fortunately, screen reads a environment variable SCREENDIR to get an alternative socket directory.

So to work around it, you can create a directory, such as ~/.screen:

mkdir ~/.screen && chmod 700 ~/.screen

and export the SCREENDIR to point to that directory:

vim ~/.bashrc

export SCREENDIR=$HOME/.screen

You can also put this line into you ~/.bashrc so that it will also take effect afterwards.

source ~/.bashrc

It will work the screen. that is all.
