Stat

Stat displays the status of a file or the filesystem a file is on.

To obtain information about a file: $ stat file

To obtain information about the filesystem file is on: $ stat -f file

Use the -c option and various format sequences to obtain tailored output or the -t format for terse (and easily parsed) output. See the stat man page for full details.

= Find out the size = You can use stat to find out a partition's size in blocks. To find out a partition's size in bytes, use fdisk as described here.
