What is /dev/pts, /dev/shm?
 
When i checked mounted filesystem on my linux box, i see "/dev/pts", "/dev/shm". What are these filesystems for?


Thanks,

/dev/pts - psuedo terminal slave.. without it, you wouldn't have a command line with terminals, etc. Read more here: http://www.linuxinfor.com/english/man4/pts.html

/dev/shm - shared memory is what I think it stands for. Its another psuedo type tmp/cache filesystem. Some say you really don't need it since its for POSIX shared memory but it might help if you have it if you don't have much memory to spare, etc.
