Let’s say, for example, you have a directory of files named x01-001; x01-002; x02-001; x02-002; x03-001… and so on.

I want to create subdirectories for each ‘x’ iteration and move each set to the corresponding subdirectory. My loop would look like this:

for i in {1…3}; do mkdir Data_x0$i && mv x0$i* Data_x0$i; done

I’ve also been using it if I need to rename large batches of files quickly.

I recently learned to use a for loop on the command line to organize hundreds of files in a few seconds.
