How can I find the number of files and inodes on a file system?

$ find / -type f | wc –l

$ df --inodes / /home

Filesystem            Inodes   IUsed   IFree IUse% Mounted on

/dev/sda1            3981312  641704 3339608   17% /

/dev/sda8            30588928  332207 30256721    2% /home

$ sudo find / -xdev -print | wc -l

642070
