Hi,
Would like compare two directories (recursively) and display only the size in GB from all sub directories in two columns in linux

subdirname      pdir1        pdir2
one                    1GB      1GB
two                    1GB      1.1GB
three                 1GB      1.2GB
four                  1.1GB      1GB

Thanks in advance

(cd pdir1 ; du -h | awk '{print $2,$1}' | sort ) > d1
(cd pdir2 ; du -h | awk '{print $2,$1}' | sort ) > d2
join d1 d2

Small change - that would display the size of each file under the directory, and use whatever size was appropriate.  To force it to use GB, and do summary sizes of the subdirectories (or files) directly in  the two directories, the du command changes from "du -h" to:
    du --block-size=G -s *

Thanks very much ..that helped.

Tried this with slight change
(cd pdir1 ; du -sh * | awk '{print $2,$1}' | sort ) > d1
(cd pdir2 ; du -sh * | awk '{print $2,$1}' | sort ) > d2
join d1 d2
