Following on from my recent upload on Linux scripting, I have yet again created a BASH script to make my Linux’ing life easier. This is also my second script created in BASH so I guess i’ve accomplished something by not running for the hills…

What I needed was a script to make creating FTP users easier on my CentOS box. Below is a list of things I needed the script to accomplish:

• Get a username from a user prompt
• Get a Description from a user prompt
• Create the new user
• Change the users password
• Add the username to /etc/vsftpd.userlist
• Add the username to /etc/vsftpd/chroot_list
• Make a directory in the home folder of the user called “ftp”
• Change the permissions and ownership on this directory
• Make a directory in the “ftp” folder called “files”
• Change the permissions and ownership on this directory
• Ask the user to create a share or not
• Get a share name from user prompt
• Make a directory in the users “files” folder with the same name as the share name
• Mount the share to the “files” directory
• Ask if the new user is the owner of the share
  • if so then change the ownershipa and permissions on the share
  • if not then just change the permissions on the share
• Finish

Here is my script for achieving these goals:

#!/bin/bash
#Creating new FTP users

##Gathering Variables
echo "Enter a username"
read Username

echo "Enter a description"
read Description

useradd -m -c "$Description" -s /bin/bash $Username

passwd $Username

echo "$Username" | tee -a /etc/vsftpd.userlist
echo "$Username" | tee -a /etc/vsftpd/chroot_list

mkdir /home/$Username/ftp
chown nobody:nobody /home/$Username/ftp
chmod a-w /home/$Username/ftp

mkdir /home/$Username/ftp/files
chown $Username:$Username /home/$Username/ftp/files
chmod 0700 /home/$Username/ftp/files

read -p "Create a share? [yn]: " CreateShare
if [[ $CreateShare = y ]] ; then

 read -p "Enter a share name: " ShareName

 mkdir /home/$Username/ftp/files/$ShareName
 mkdir /home/shares/$ShareName
 mount --bind /home/shares/$ShareName /home/$Username/ftp/files/$ShareName
elif [[ $CreateShare = n ]] ; then
 read -p "Enter the pre-existing share name: " ShareName
 mkdir /home/$Username/ftp/files/$ShareName
 if [ -d /home/shares/$ShareName ] ; then
  echo "Mounting share"
  mount --bind /home/shares/$ShareName /home/$Username/ftp/files/$ShareName
 else
  echo "Cannot find the share name : $ShareName"
 fi
else
 echo "Not a y or n"
fi

read -p "Is $Username the owner of this share? [yn]: " ShareOwner
if [[ $ShareOwner = y ]] ; then
 chown $Username:$Username /home/shares/$ShareName
 chmod 0775 /home/shares/$ShareName
else
 echo "$Username is not the owner of $ShareName"
 chmod 0775 /home/shares/$ShareName
fi

echo "Finished creating user : $Username" * Insert your code here

Hopefully somebody gains something from this, probably not though. Enjoy!
