I have a number of folders in unix (with different names) that should all have the same few file names in them. I want to find the folders that DON'T have a specific file:
For example:
A/
-->a.dat
-->b.dat
-->c.dat
B/
-->a.dat
-->b.dat
-->c.dat
C/
-->a.dat
-->c.dat
When looking for the b.dat
file, how do I figure out that the C
folder doesn't have it?
