Other Tips

Check disk space usage and view the partition table

  1. Open System->Administration->Disks .

  2. Select the Harddrive, then the Partitions tab

  3. Each partition will be listed under Partition List, with disk space and mount point.

List devices

To list mounted devices, in a terminal enter:

mount

The listing shows the device (such as a hard disk partition), the mount point (where you access the files), the filesystem type and the mount options.

This example shows the hda2 hard disk partition mounted as '/', with the filesystem type ext3. The partition is mounted with two options, one to allow the device to be read from and wrote to and the other to remount the device as read only in the event of any errors.

          /dev/hda2 on / type ext3 (rw,errors=remount-ro)
        

To list PCI devices:

lspci

To list USB devices:

lsusb
