You can free up unused memory under Ubuntu/Linux Mint using this command: sudo sysctl-w vm.drop_caches=3. NOTE: this action won't make your system faster nor it will affect its stability and performance, it will just clean up memory used by the Linux Kernel on caches.ere is another command that can help you free up memory either used or cached (page cache, inodes, and dentries): sudo sync && echo 3 | sudo tee /proc/sys/vm/drop_caches. NOTE: You can use cron jobs to schedule the commands above to run at specific time intervals.
You can just use fdisk to get rid of any partitions, just as you would on Windows (the Linux fdisk is way more powerful). If you do this, the data still exists on your hard disk, but it's harder to get to. If you just want to wipe the system to do a re-install, then fdisk is the way to go. If you want to erase the data because you're getting rid of the drive then fdisk is the wrong way to go. You can use 'dd if=/dev/zero of=/dev/hda' to write 0 across the entire hard drive. All your data is then replaced with 0. You might need to change /dev/hda to the device file for your hard disk.
