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

Example of said Black Magik?

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.

Check out rename

$ touch foo{1..5}.txt
$ rename -v 's/foo/bar/' foo*
foo1.txt renamed as bar1.txt
foo2.txt renamed as bar2.txt
foo3.txt renamed as bar3.txt
foo4.txt renamed as bar4.txt
foo5.txt renamed as bar5.txt
$ rename -v 's/\.txt/.text/' *.txt
bar1.txt renamed as bar1.text
bar2.txt renamed as bar2.text
bar3.txt renamed as bar3.text
bar4.txt renamed as bar4.text
bar5.txt renamed as bar5.text
$ rename -v 's/(.*).text/1234-$1.txt/' *.text
bar1.text renamed as 1234-bar1.txt
bar2.text renamed as 1234-bar2.txt
bar3.text renamed as 1234-bar3.txt
bar4.text renamed as 1234-bar4.txt
bar5.text renamed as 1234-bar5.txt
