Shell Programming and Scripting

Assuming that you meant ls -r icgorldi_*.xm instead of s -r icgorldi_*.xm, that will give the the name of the file with the highest tag number (i.e., something like icgorldi_2421599.xml).
And that will set fn to something like:

Code:

-rw-r--r--      1 banjobs  jobsub       125 Jun 17 10:35 icgorldi_2421597.log

either for the same or a different file (this time choosing the file with the most recent modification timestamp instead of the file with the highest tag number).
And why would invoking a news reading utility (rn) with ten operands be expected to rename a file. Is there some significance to the new name you want to assign to this file? It almost looks like it is named for the day that would be 1000 years ago tomorrow???

Whatever the problem, saying "this does not work" instead of showing us what it does do, what you wanted it to do, and showing us any diagnostic messages it produced when you ran it means that we have absolutely no information about what went wrong other than our wild imaginations.

Help us help you; show is what is going on!
If you would set fn using one of them methods I suggested before:

Code:

fn=$(ls -r icgorldi_*.xml | head -n 1)

if you want the file with highest tag number, or:

Code:

fn=$(ls -t icgorldi_*.xml | head -n 1

if you want the file with the most recent modification timestamp, and then used:

Code:

mv "$fn" icgorldi_06191015.xml

it MIGHT do what you want.

How you would write a program to make up the two seemingly random new local and remote filenames is also hard for us to guess. Are you passing in these names as parameters? Are they somehow created using some transformation of today's or tomorrow's date?

Again, if you would give us a CLEAR, explicit description of your environment and what you are trying to do, we would be happy to help you. If you keep us in the dark, you're either going to get silence or wild guesses that are not likely to lead you in the right direction.

Sorry for the delay but yes, I got my answers
