I would like to know the meaning of computer:///
How to go with the command line to a file at location computer:///
31 Answer
The computer:/// scheme is provided by GVfs:
List of drives, volumes and mounts
That's all it really means. It's one of the schemes understood by the file manager. The Ubuntu's file manager Nautilus is built using Gtk,Gio, and GVfs libraries, hence why such uri scheme is available. Others, such as PCManFM also support it. In general, this is known as Uniform Resource Identifier which originally was meant for web technologies. Interestingly enough, some of the ideas are used on desktop as well. URI is one example, while GSettings use fully qualified domain name scheme, similar to how DNS would resolve a website.
Note, however, that the original GVfs link suggests computer:/// uri may be deprecated eventually. And exactly because Nautilus uses Gio/GVfs, this syntax is understood. If a file manager or another application are built with Qt for example, there's no guarantee it will be understood there.
How to go with the command line to a file at location computer:///
You can't, unless you write a command-line application that uses Gio/GVfs and recognizes computer:/// uri scheme. It's a virtual location, and doesn't have a real directory associated with it, so we can't simply cd into it in shell. Since the description states that it's basically a list of drives, volumes, and mountpoints it is sufficient to use lsblk command to get a listing of block devices and associated mountpoints
$ lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 28G 0 disk
└─sda1 8:1 0 28G 0 part /
sdb 8:16 0 111.8G 0 disk
└─sdb1 8:17 0 111.8G 0 part /mnt/ubuntuList of drives ? Use udisksctl status
$ udisksctl status
