I want to find out the last time a filesystem was mounted on Linux (Debian). Any help?
Update: well that was too easy
$ sudo tune2fs -l /dev/sda1 tune2fs 1.41.11 (14-Mar-2010) Last mounted on: / Filesystem magic number: 0xEF53 Filesystem revision #: 1 (dynamic) Filesystem state: clean Errors behavior: Continue Filesystem OS type: Linux Inode count: 7028736 Filesystem created: Sat Nov 14 20:49:49 2009 Last mount time: Wed Jun 9 18:19:42 2010 Last write time: Thu Jun 3 09:38:18 2010 Mount count: 20 Maximum mount count: 32
tune2fs handles ext4 partitions too, I just don't have one handy.
