Ubuntu Tricks

Copy with speed and progress:

 rsync -r -v --info=progress2 ssh user@remote-system:/address/to/remote/file /home/user/

Clear cache / buffer:

sudo sync && sudo sysctl vm.drop_caches = 1|2|3

or

echo 3 | sudo tee /proc/sys/vm/drop_caches

Periodically clear cache / buffer:

sudo crontab -e
0 * * * * /usr/bin/sync; /usr/sbin/sysctl vm.drop_caches=3

vfs cache threshold:

sudo sysctl vm.vfs_cache_pressure=100
