[SOLVED] how do I add users with same name to system?

[pauhn]

I have a useradd script that can be found here: [Bash] #!/bin/bash #useradd script while true; do echo Please Enter First Name - Pastebin.com

I need to add users that have the same name, while keeping with the current scheme, I'd just like to have numbers at the end of the user, for example joeuser, joeuser1, joeuser2... Basically, keeping with the current naming scheme, I would like to modify the script to automatically add a number to the end of the username when I have users that have the same name.

I just can't seem to find the command and argument that would allow me to do it. All help is greatly appreciated.

The script is interactive, why don't you just have it find the last username that would conflict, have it echo that on the screen and ask you for the username? Efficient. FWIW, having usernames where only the last character is different will always make your future scripts more difficult since they are so much alike.

would I just do

uniq -d /etc/passwd
echo You have to add a number to user

I think I'm starting to over think this.

I tried working on it, I added a few new lines, namely at line 25-29. I seriously thought that this would solve my problem. The code worked fine by itself, but when I add Joe User (userj) and and John User (userj) it does not append a number to the last user I added. I have the code in a pastebin here - [Bash] DECISION=yes while [ "$DECISION" = 'yes' ]; do echo Please, enter the u - Pastebin.com

I solved it! here's the script, maybe it can help some other people

#!/bin/bash

decision=yes
  while [[ $decision = 'yes' ]]; do
  
  read -p "please, enter the users first name." fname
  read -p "please, enter the users last name." lname
  read -p "please, enter the users initial group." igroup
  read -p "please, enter any additional groups the user belongs to." agroup

  igroupl=$(echo "$igroup" | tr '[:upper:]' '[:lower:]')
  agroupl=$(echo "$agroup" | tr '[:upper:]' '[:lower:]')
  lnameu=$(echo "$lname" | tr '[:lower:]' '[:upper:]')
  fnameu=$(echo "$fname" | tr '[:lower:]' '[:upper:]')
  usrnm1=$(echo "$lname" | tr '[:upper:]' '[:lower:]')
  usrnm2=$(echo "$fname" | cut -c 1 | tr '[:upper:]' '[:lower:]')  
  usrnm=$usrnm1$usrnm2
  
  useradd -c "$fnameu $lnameu" -g "$igroupl" -g "$agroupl" "$usrnm"
  echo 123456 | passwd "$usrnm" --stdin

  if getent passwd "$username" >/dev/null; then 
    for i in {1..50}; do 
      getent passwd "$username$i" >/dev/null || { username=$username$i; break; }; 
    done; 
  fi
  
  read -p "would you like to add another user?(yes/no)" yesno
  decision=$(echo "$yesno" | tr '[:upper:]' '[:lower:]')
    
  doneloop=1
  while ((doneloop == 1)); do
    if [[ $decision == 'yes' ]]; then
      decision=yes
      doneloop=2
    elif [[ $decision == "no" ]]; then
      echo "thank you for using this program"
      doneloop=2
    else
      echo "please use a correct option.(yes/no)"
      read yesno
      decision=$(echo "$yesno" | tr '[[:upper:]]' '[:lower:]')
    fi
  done
done
