The loop I showed you above may not be what you want to do, but it is EXACTLY what the code you provided will do!

The command:

Code:

find . -name "EV"

finds and prints the pathname of every file in and under the current directory where the final component of that pathname is EV. (Not a name containing EV; a name that is exactly EV.) And the exit status from that find command will be zero no matter how many pathnames it prints. So, whether or not find finds any files named EV, it won't affect the behavior of the rest of your script.

By convention, a filename ending with .pdf should be a regular file encoded in the portable document format invented by Adobe. If your filenames follow this convention, there is absolutely nothing in your script that will rename any directories. Furthermore, with the code you have shown us, as I said before, every file in the file hierarchy rooted in the current directory whose name ends with .pdf will be moved (one at a time) to E-test.pdf until you only have one filename ending with .pdf and that file will be named E-test.pdf.

Please show us a list of directories and files in those directories and explain what changes to those files you want your script to perform. If we can figure out what you want to do, maybe we can help you write a script that will do it.

But, trust us, the script you showed us will not do anything at all like what you seem to want this script to do.
