Question /dev/sda

Can any one explanation This point in unix

/dev/sda

rw-rw-rw

Thank you...

 

I want

example of a file representing the hard disk storage device

 

/dev/sda is a device name in Linux. Since no number is given this means the entire hard disk detected by the Bios.

To see the characteristic of files you must mount a partition on the filing tree of Linux. The common point is /mnt or /media.

You also need to be in root (Admin) in order to mount a partition so if you want to see all the files and their characteristics in partition sda1 the commands in terminal, say in Ubumtu family, are

Code:

sudo su
mkdir /mnt/please_mount_here
mount /dev/sda1 /mnt/please_mount_here
ls -l /mnt/please_mount_here

The 1st line is to become super user or root user
2nd line is to create a subdirectory
3rd line is to mount a hardware on the specified subdirectory
4th line is to list the files in details.
