Linux Tip: List Directories by Size – du
Use the du comand to list your directories by size: user@ubuntu:/boot$ du -hs * 632K abi-2.6.32-21-generic 120K config-2.6.32-21-generic 1.5M grub 7.7M initrd.img-2.6.32-21-generic 164K memtest86+.bin 1.7M System.map-2.6.32-21-generic 4.0K vmcoreinfo-2.6.32-21-generic 3.9M vmlinuz-2.6.32-21-generic In this, ‘grub’ is a directory in the location. This command has a lot of options but usually I am just interested in this.
