minus-squareanonymouse2linkfedilinkarrow-up7·9 hours agoI recently learned to use a for loop on the command line to organize hundreds of files in a few seconds.
minus-squareanonymouse2linkfedilinkarrow-up8·8 hours agoLet’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.
