List the files in a folder that are using up the most disk space. The du -h command will take care of this. This command will list the files in a human readable format.

If there are a lot of files in the directory, only show the top 10 largest files using this command. du -h | head -n 10.
iMac305:Downloads admin$ du -h | head -n 10 59M ./Music 36K ./openvpn-2.3.4/build/msvc/msvc-generate 60K ./openvpn-2.3.4/build/msvc 88K ./openvpn-2.3.4/build 4.0K ./openvpn-2.3.4/contrib/OCSP_check 12K ./openvpn-2.3.4/contrib/openvpn-fwmarkroute-1.00 8.0K ./openvpn-2.3.4/contrib/pull-resolv-conf 32K ./openvpn-2.3.4/contrib 32K ./openvpn-2.3.4/debug 52K ./openvpn-2.3.4/distro/rpm |
Here is another way to list the top 10 largest files in a directory in order from largest to smallest using the /bin/ls command. The ls -Slah | head -n 20 command is a good way to list the disk space hogs in your ~/Downloads directory.
