If you don’t want your mounted drives to show up on your Ubuntu GNOME desktop, all you need to do is mount them somewhere other than /media/. Here is an example:
mount /dev/sdb1 /mnt/usbdrive

Here’s a quick tip on how to delete files that are a certain amount of days old. In my example, I use 365 days.
find / -type f -mtime +365|xargs rm -f
You could easily replace 365 with any amount of days to achieve a different goal.

Need to find out what all the file types in a certain directory are? Simple!
Execute the following on the command line:
find /path/here/ -type f -print | xargs file
I typed: find /home/adam/test/ -type f -print | xargs file
The output will look something like this:
/home/adam/test/music.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, mono 44100 Hz
/home/adam/test/package.deb: Debian binary package (format 2.0)
/home/adam/test/file.tar.gz: gzip compressed data, from Unix, last modified: Tue Jun 20 12:51:11 2006
/home/adam/test/widget.xml: ASCII text, with CRLF line terminators
/home/adam/test/logfile.txt: empty

If you’re worried about FTP users exploring outside of their home directory, you want to set up what is called a chroot jail.
To do this, open the /etc/vsftpd.conf file:
vim /etc/vsftpd.conf
and make the following modifications (line should be uncommented):
chroot_local_user=YES
After you save the file, restart vsftpd:
/etc/init.d/vsftpd restart
Now all users will be jailed to their own home directory when using FTP.
Now, lets say you only want to jail certain users, and allow other users to browse other directories. To do this, you’ll want to again edit the configuration file.
vim /etc/vsftpd.conf
uncomment the following lines:
chroot_list_enable=YES
chroot_list_file=/etc/vsftpd.chroot_list
After you save the file, restart vsftpd:
/etc/init.d/vsftpd restart
Now you will need to create the /etc/vsftpd.chroot_list file and add in users you do NOT want to jail. By default, all users will be jailed. In the /etc/vsftpd.chroot_list file you can specify what users to allow to browse all directories.
