How to process every second file in bash?

Question

I have a directory with a few dozens of files. I would like to do something with every second file from this directory. By now I only used find command but with thi

Answer 1

I had every file twice, and needed to delete every second file. Find just returned me random files, therefore I added a sort. It now looks like this:

#!/bin/bash
DIRNAME=""
for file in `find $DIRNAME -type f | sort | awk 'NR % 2 == 0'`; do
  echo "going to modify" $file
  #  ls -laFh $file           # show file details
  #  rm $file                 # delete file
  #  mv $file     # move file to 
done

put this in a file called scriptName, run

chmod +x scriptName

and start it by calling

./scriptName
