shell - How to develop this sort script further -

i have small interactive unix script takes terminal command input chosen file type , upon receiving such iterates through large folder of unsorted files on desktop , pulls files of chosen selection new sorted folder.

i.e. user types jpg in command , jpg files pulled out of unsorted folder , sorted folder.

it works terrific stands, develop script further instead of file types being pushed communal sorted folder, have jpg files being pushed dedicated folderjpg, png files pushed in folderpng , docx files moved docxfolder.

how can achieve such in leanest possible manner assuming these dedicated folders file types mentioned have been created on desktop.

#!/bin/bash  echo "good morning, please enter file type name sorting [enter]:" read extension mv  -v /users/christopherdorman/desktop/unsorted/*.${extension} /users/christopherdorman/desktop/sorted/ if [[ $? -eq 0 ]];     echo "good news, files have been processed" fi 

i write way:

read -p "good morning, please enter file type name sorting [enter]:" extension if cd /users/christopherdorman/desktop;     destination="folder$extension"     # ensure destination folder exists     mkdir -p "$destination"     if mv  -v unsorted/*."$extension" "$destination";         echo "good news, files have been processed"     fi fi
