The |sort isn't necessary since the shell always returns wild-card
expansions in sorted order. In fact the ls isn't necessary either since
the shell has already generated the list.

You are correct, it is not be necessary in the example - I put it in
as an option if you were not sorting on the entire file name, but on
a specific field. You have more options on how you sort by piping
the list though sort. In this case, the -k or -M options may be handy.

for i in something*
will do the same thing.

file_num=$(cut --delimiter=_ -f1 $i)
while [ $count -lt $file_num ] ; do
echo Missing file number $count count++
done
done


This is great. I think now I have enough pieces to make something
work. I appreciate all the help.

The above doesn't help if you lose the 1st or last bunch of files. Do
you always get the same set every day?

It will catch if the first file is missing - the first entry will be
greater then count. If you know in advance how many files there
should be, you could add a test to see if the last file is
xx+number, as well as using that as an exit for the while loop.

As I had stated in the comments after the script, it was not
intended as a finished solution, but as a starting point for
building something that fit data better.
