Have to insert a dot after 9th position from last character.
OR Is there a way to convert bytes to GB format

where is this list from? commands like df or du have switches to display result in GB format.
from the other hand you can use sed/awk/perl/python/whatever to do that. Which one do you prefer?

Grab your favourite language and divide by either 1000 or 1024 until you get your required result. You can do it the way you wish as well with simple text manipulation.

you forgot to say which language you need to do this in.

What command are you using? For instance if you're using df, there is a human readable format argument:

Code:

df -h

It seems you have these values as strings (originally extracted from a MSWin system), so 3 options:

As above, if you can mount them from a Linux box, then 'df -h'.

If not, string manipulation using 'rev' eg

Code:

echo 12345|rev

and the links from BW-userx.

You're probably better to calc it as per grail.
