Hello,
I currently have very little experience with Shell scripting and trying to create a script for the purpose of collecting the size of a couple sizes on 4 different Hosts. The Idea is to collected the information from the files in which the script is kicked off on, store the values into Variables, SSH to the next Host and repeat for the remaining 2. With Variables Collected I would like to compare the sizes and output that they matched.
This is what I have come up with so far but not the most familiar with constructs and especially the SSH Process.
If someone could help get this functioning, or possibly has suggestions for more efficient scripting with less repetition It would be greatly appreciated.
Is there a command that will return the name of the largest file within a directory? If so, can I set the returned filename into a variable? (4 Replies)
