Question

I have a database of files in a folder. I wish to sort the files containing *C: into one folder and the files containing *c: into another folder. How can this by achieved?**

I can use *.krn to access every file.

Answer 1

$ grep --help | grep with-matches
-l, --files-with-matches  print only names of FILEs containing matches

What now depends on how many files there are and how paranoid you must be about their names. From the simplest

mv $(grep -l pattern files) target

to the most robust

grep -l -Z pattern files | xargs -0 mv -t target-directory --
