Compression ratios of .tbz file
Hi,
I have a question about finding the compression ratios of a zip (bzip2) file.I have written a procedure which upon certain criteria tar's and bzip2 certain directories and moves them to a near line storage.
Yesterday I happened to stumble upon it. The procedure has tared and bzipped 6 GB of data to 800MB. Is there any attribute in tar command which would yield a summary of the compression.Though I have gone through the man page of tar, I have not found anything affirmative.
Thanks in advance
Syed
