Ubuntu automounts USB -fs to
/media/usb/something. How is this in OSX? I cannot find anything in /media below.
All volumes (CDs, USB, harddrives, etc) are mounted into /Volumes.
After inserting a USB stick called USB I see the following:
alex@smiley:/Volumes|⇒ ls -lrt total 8 drwxrwxr-t 30 alex staff 1088 Aug 4 14:34 USB drwx------ 1 root wheel 568 Aug 4 23:59 Family Backup drwxr-xr-x 6 root wheel 340 Aug 5 00:00 Time Machine Backups lrwxr-xr-x 1 root admin 1 Nov 14 20:55 System -> / drwxr-xr-x 39 root wheel 1394 Nov 14 20:57 SmileyBackup
In addition there you can see that my main drive is System. OS X creates a link to / for it automatically.
Also, Smiley Backup is another disk, and Time Machine Backups is a TimeMachine volume, and Family Backup is a remote shared drive I've mounted from another system.
As already mentioned, you can view almost all mounted devices in
/Volumes. Although, the newer iOS devices do not show up there.
Alternatively, you can use
diskutil (which does not require superuser access.)
$ diskutil list
If you want more details on a specific mounted device you might try:
$ diskutil info [diskname]
