I need to have a Unix command set (Single line commands) which can save my time when I am dealing with bunch or batch of items. Few examples of my reqmt is as follows.
1) Changing the permissions for a all dirs&fiels for whole dir structure (including sub folders)
2) Changing the ownerships for a all dirs&fiels for whole dir structure
3) Status query commands over network
Apart from the above I am looking for any kind of common tips and shortcuts which can save my time.
One more thing is that the command set should be independent of the Unix flavor.
Requesting everyone to share the links, docs, pdfs for the above.
