How to Calculating space used in GB for any particular directory in UNIX?
How to Calculating space used in GB for any particular directory in unix



Currently I am using : df -h which gives me space for each mout point

Code:
ldndyn1:/vol/v01/dyn/sbcexp/dyn
                      1.1T  999G   29G  98% /sbcimp/dyn


but I need for some internal particular directory size eg: directory/folder is DIR_A:

Currently I am trying with below command:
Code:
du DIR_A  |awk '{sum +=$1} END {print sum}'

it giving me output as : which I am thinking in bytes?
Code:
31758932



Please advise on best approch

It means what it says, it doesn't have permission to access that directory. If that directory's not important, you can ignore that error.

To get a sum of one particular directory, du -hs /path/to/folder 2>/dev/null The -s means 'summary', instead of listing folders inside.
