Subject: [gentoo-user] how to find if a program is using a particular /dev device?
Date: Thu, 17 Nov 2005 23:54:57 -0800 (PST) [thread overview]
Message-ID: <Pine.LNX.4.64.0511172350080.14423@mail.magrittesystems.com> (raw)
I have a custom device driver in /dev/ that can only be used by one
program at a time. Since the device is /dev/ttyUSB0, I can see if anyone
is using it by:
ls -l /proc/*/fd/* | grep ttyUSB0
Is there a utility or other better way I can discover which process, or
better, which program, is using a particular device?
Thanks,
Michael
