Hi Friends,
How to find out a specified directory size on unix? Is there any
direct method?

How about something like "du -k <directory name>", e.g.:
du -k /tmp
and
du -k /tmp | sort -n

?

Your question isn't very clear: do you mean the size if the special
file for the directory or do you want the size of the contents of
the directory? And do you want to find out via a shell command or
do you need to figure out the size from e.g. a C program?

If it's the size of the contents of a directory (the size of the
file for a directory typically is only of small interest) and
you want to get it (in kB) with a shell command simply use

du -s -k <name of directory>

From a program (and if you satisfied with kB resolution) the
simplest method probably would be to invoke the above shell
command via popen() and simply read in the result.

Is the directory size the number of bytes in the inode, the number
of linked files, or the cumulative size of child files?

Or, if you want to save two keystrokes,

du -sk <name of directory>

I'm not picky ... just that I often use the "du" command and have gotten
used to typing "du -sk".
