[gentoo-user] /dev full of pty* tty* - is it normal?
Hi, I just noticed I have *a lot of* tty/pty files in dev: obelix ~ # ls -l /dev/pty* | wc -l 256 obelix ~ # ls -l /dev/tty* | wc -l 325 They have names from /dev/ptya0 till /dev/ptyzf, then pty0-pty63, and ttya0-ttyzf. Is this normal? I thought udev creates device-files as they are needed, so I'm surprised to see so much of them... Jarry -- ___ This mailbox accepts e-mails only from selected mailing-lists!

Wonko Thanks for info. FYI I just checked some debian-machine and it has only 63 tty's and none pty. I always thought it had something to do with number of terminals started by inittab. Anyway, it looks so that udev is not dynamic for all kind of dev-files... Jarry -- ___ This mailbox accepts e-mails only from selected mailing-lists!

Wonko Same thing here. It's a old install so I expected some old things before udev took over. I guess udev cleaned it up some. Seems normal tho. Dale :-) :-)

Looks different on my machine: # ls -l /dev/pty* | wc -l zsh: no matches found: /dev/pty* 0 # ls -l /dev/tty* | wc -l 65 It may have something to do with your kernel settings.
