get output of du / ls command - currently ugly code ...

[Esmail]

Hi all,

Essentially all I want to know the size of a directory, and the size
of a zipped tarball so that I can compute/report the compression ratio.

The code I have seems hideous, but it seems to work. Surely there is an
easier,more elegant way to do this?

dir_size = os.popen('du -sk somename')
data = dir_size.readlines()
dir_size = int(data[0].split()[0])
print 'dir size: ', dir_size

tar_size = os.popen('ls -s somename.tar.gz')
data = tar_size.readlines()
tar_size = int(data[0].split()[0])
print 'tar size: ', tar_size

Thanks
Esmail

Try using os.path.getsize(somename.tar.gz)

Beautiful! .. that takes care of the tarball .. but it doesn't seem to
work for reporting the total size of the directory. Any suggestions how
to do that in a nicer way?

I just looked through os.path.* and there doesn't seem to be a function
to report what "du -sb" would.

Thanks for your help,
