how to move Files to a folder using mv in bash with condotions?

I was writing this code to organize my downloads folder so it wouldn’t be messy. i want the files to be moved to their proper folder like for mp4 it should go to the Videos folder. but the code is not working

#! /bin/bash

if [[ -d Videos/ ]] && [[ -d Compressed/ ]] && [[ -d Music/ ]] && [[ -d Pictures/ ]] && [[ -d Executables/ ]] && [[ -d Misc/ ]]

I guess it’s from ‘if’ statement but i don’t know how to fix it because i’m quite new to bash. the mkdir is working but all of the “if [[ -f *.mp4 ]]” was not.

Filename expansion is not performed within the bash compund command [[...]]. So, for instance, *.7z in [[ -f *.7z ]] means literally a filename *.7z. That’s why your script won’t work. The script below may be what you want:

#!/bin/bash

mkdir -p Videos Compressed Music Pictures Documents Executables Misc || exit

for f in ./*.{7z,rar,zx,zip,gz,iso}; do
    [[ -f $f ]] && mv "$f" Compressed
done

for f in ./*.{mp4,mov,wvm,mkv}; do
    [[ -f $f ]] && mv "$f" Videos
done

for f in ./*.{mp3,wav,ogg}; do
    [[ -f $f ]] && mv "$f" Music
done

for f in ./*.{png,jpg,jpeg,svg,webp}; do
    [[ -f $f ]] && mv "$f" Pictures
done

for f in ./*.{doc,docx,pdf,pptx,ppt,xls,xlsx}; do
    [[ -f $f ]] && mv "$f" Documents
done

Notice the use of -p option in mkdir. The missing directories will be created and existing directories will be ignored without an error by this option.
