How to programmatically detect a mounted device

| I have a gumstix running linux version below. | | # uname -r | 2.6.11gum | | It has a MMC slot which I use for collecting log files. My | requirements is that if the MMC card is mounted, my application would | archive log files to the MMC card. If the card is not mounted (user | not inserted), the my application would not archive log files, so as | to not write to the internal flash. | | My question is: how can I programmatically detect whether or not a MMC | card is mounted?

By scanning the contents of /proc/mounts (if you have /proc enabled and mounted).

Yes, thank you. I do see the entry in the file after mounting the card.

Here is a little /bin/sh routine that you probably might find useful, or can modify to suit...

is_reader() { test=$( cat /proc/scsi/usb-storage*/* 2> /dev/null | grep "Card Reader"; cat /proc/bus/usb/devices 2> /dev/null | grep Cnt=0[1-9] ) if [ "$test" = "" ]; then return 0 else return 1 fi }
