Shell Programming and Scripting

quick question.. say i have few files in D or E drive.. i want to paste them in Filesystem that is /home/vivek folder... but when i try to do that it shows some error saying "There is not enough space on the destination. Try to remove files to make space."

but i think its due to authorization problem cause when i opened vi editor in the very same path and typed few things and saved it it dont give any problem at all... i am using ubuntu.. so can anyone tell me how to do this...?

When you used vim were you root?

A Linux system lies to it's users about free space. This is so you can still use root, and root stuff functions normally regardless of the free space. For instance, sockets can still be made as root in /tmp. You might have 5% free space.

A command that will tell you about free-space including how much users see and how much is left for root is "df -h"

A command that will tell you about what is using space is du, which scans directories for files and how much space is being used. Check the manual, because you will want totals and stuff. Check out Google on the subject, there are easy guides to these tools.

It also depends on the size of the file that you are trying to copy. when you use vi editor, it will be a small file but the actual file you are copying may be bigger than the size of the filesystem.

So you can use df -k to see how much space available in the filesystem. If you dont have enough space then you need to increase the size of the filesystem.

oh okay thanks :-)
