Hello...I am a beginner
I want to write a script name myuseradd
I want to add user without useing useradd command

1- Check if user is root. If not the script cannot be run and it exits.
2- Check the number of arguments. If none the script exits.

Can someone give me a clue ???

In puppet, it would look like this:

user { 'abdelellah':
  ensure  => 'present',
  comment => 'Abdelellah',
  uid     => '1000',
  gid     => '10',
  home    => '/home/abdelellah',
  shell   => '/bin/bash',
  password => '<Abdelellah_HASH>',
  managehome => 'true',
}

See? No useradd

But I assume, what you are looking for is directly editing the files containing the account information.
And as this looks like a homework question to me, I suggest
- you read the man page of useradd to figure out, which files contain the account informations
- then look at the files
- then decide how you would implement your own useradd

man useradd

Manually adding users and the shadow file...

This sounds like a homework question, which are not allowed on this forum. I am closing this thread.
