How to find out how much disk space is remaining?
You can use two commands: df and du.
df - report file system disk space usage
Usage works like such:
df -h
Which should output something like this:
Filesystem Size Used Avail Use% Mounted on
/dev/vzfs 20G 3.5G 16G 18% /
The -h flag provides human readable output (which makes reading of the output - easier).
du - estimate file space usage
A second tool is with du which is a slower approach but will give you a better break down of a per directory. Information on that can be found in How to determine where the biggest files/directories on my system are stored?
There are several good command line tools for reporting disk usage. Use the one that's most helpful to you:
df
$ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 56G 4.4G 48G 9% /
none 1.5G 256K 1.5G 1% /dev
none 1.5G 472K 1.5G 1% /dev/shm
none 1.5G 400K 1.5G 1% /var/run
none 1.5G 0 1.5G 0% /var/lock
tmpfs 1.5G 596K 1.5G 1% /var/log
tmpfs 1.5G 8.0K 1.5G 1% /var/log/apt
/dev/sdb2 840G 579G 253G 70% /home
df is installed by default.

You can use this command to find out how much space files in your home directory (replace ~/ with / for entire filesystem) and sort by largest files
du -sk ~/* | sort -n
