Debian About adding users from a text file using bash

hello,

I try to add users from a text file with this form:

username:groupename:homedir


first i extract data which is separated by ":"
then i use useradd to add users/groups.

but,,, my code doesn't works :


Code:
#!/bin/bash

echo "give me a text file: "
read dir


# control if the file is valid
if [ -f $dir ]
then
       for user_dets in $(dir)      #loop and extract data
       do
                    user= echo "$user_dets" | awk -F\: '{print $1}'
                    group= echo "$user_dets" | awk -F\: '{print $2}'
                     home= echo "$user_dets" | awk -F\: '{print $3}'
                 
                     useradd -g "$group" -d "$home"  $user
 
        done
else
        echo "file is not valid"
fi

I found this code which probably do the same as awk 'also doesn't works':

Code:
user = $(echo $ligne | cut -d':' -f1)

Can someone help me please?
