for the mb and gb you can do `df -h`

to know what is unwanted, you will have to go into various diretories, that you use to download files and do `du -h *`, then you will see what is taking up alot of space.Then from there make the decision whether its needed or not.

Experience and local knowledge.
The units are in the df output: "1K-blocks".
The find command. But the /var file system is ~1000 MB (not mb which means one thousandth of a bit).

From the df output, /var is ~1 GB. That is not very big; you may be better off increasing its size than looking for unwanted files, if possible.

/var/log has log files, including old ones but they are usually managed by logrotate and are likely to grow back to the current total size again.
