mkdir with ascending sequential suffix and mv one file into each folder

Question

ls -1 | sort -V > txt_list

and

cat txt_list

gives

ASOFJ.txt
BJWIF.txt
CWORI.txt
...

I want to mkdir with suffix in ascending order like folder_1, folder_2, folder_3

and mv ASOFJ.txt folder_1 , mv BJWIF.txt folder_2, mv CWORI.txt folder_3

I have tried

num=0 ; while read p ; do ( num=$(expr $num + 1) && mkdir "folder_"$num && mv $p "folder_"$num ) ; done < txt_list

But it didn't work.

Do you have any idea on a one-liner that executes the above?

Thanks.

let c=0; for i in $('ls'); do c=$((c+1)); mkdir -p folder_$c; mv $i folder_$c; done

This should do it, I think.

Explanation:

define variable c
go over each element in ls
- add 1 to c
- create folder with suffix c
- move element to folder

Thank you Malik! May I know how to modify to add leading zeros to the folder name i.e. folder_001, folder_002 and folder_003? – Johnny Tam Sep 21 '21 at 08:27

#!/bin/bash

counter=1
while read line
do
    mkdir "folder_${counter}" && mv $line "folder_${counter}"
    ((counter++))
done <<< $(ls -1 | sort -V)
