Bash script for renaming files to consecutive numbers in multiple directories

[lilipop]

hello,
i have a problem very similar to this dude:
https://stackoverflow.com/questions/22880570/bash-script-for-renaming-files-to-consecutive-numbers-in-multiple-directories

but my problem is slightly different
the extensions of my files are not all jpg. i have various file types and i want to keep that extensions.
so, i have changed the code to this:


#!/bin/bash
for dir in $(find -type d \( ! -name '.*' \))
do
i=1;
ext=
for file in $(find "$dir" -name '*.*')
do
ext="${i#*.}"
a=$(printf "%02d" $i)
new=${file%/*}
echo "mv $file $new/$a.$ext"
let i=i+1
done
done


got some inspiration from here too: https://ubuntuforums.org/showthread.php?t=1355021


so, the input would be like this:


Folder1
-> AD01
-> DSC123.jpg
-> DSC124.php
-> AD02
-> DSC234.png
-> DSC1455.exe
-> AD03
->...
-> AD04
->...
->...
Folder2
->...
...
and the output would be like this
Fo1
-> Pg1
-> Fo1_Pg1_1.jpg
-> Fo1_Pg1_2.php
-> Pg2
-> Fo1_Pg2_1.png
-> Fo1_Pg2_2.exe
-> Pg3
->...
-> Pg4
->...
->...
Fo2
->...
...




thanks

I would break this down into 2 separate steps and make a script for each that generates a script with lots of mv and rename lines.

*.* is an MS-Dos thing because extensions are treated differently in that OS. Unix doesn't care. * is the same. File globbing is a subset of the regex language.

If I had to do something like this every day for 500 directories and 20000 files, I wouldn't use bash. I'd use perl.
