[Techtalk] /dev/shm

[David Sumbler]

In my /etc/fstab file is a line which reads:

none         /dev/shm tmpfs    defaults  0 0

I assume that line was added by my Fedora Core 4 system (or its
version 2 predecessor), because I'm sure I didn't!

'df' reports

none         tmpfs    316M     0  316M   0% /dev/shm

And 'ls -ld /dev/shm' gives

drwxrwxrwt  2 root root 40 Jan  8 16:39 /dev/shm

the time being when I last rebooted the computer, I think.  /dev/shm
itself is empty, currently at any rate.

What is this, what is it used for, and by what?

David
