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?

NOTES

       YP/NIS, NIS+ and LDAP users should be aware that it's possible to have conflict with users configured in here with the result that an error
       will occur.

       You  should  ensure that local user's home accounts are located on local filesystems - e.g. creating a new entry in /home when it's mounted
       with automount will not work and as such the user may not be created.
