adduser.sh

I had to add a few lines to adduser.sh , a little script I wrote a while ago, in an effort to come up with an easy way ( for a friend and inexperienced Unix admins in general ) to add users to an FTP server --Ubuntu 12.04 LTS but this script should work on all Linux distros.

#!/bin/bash

##adduser.sh
###Add a system user
####g0 2010 ,kod.ipduh.com

INTERACTIVE=1

GROUPID=""
GROUPNAME=""
USERID=""
USERNAME=""
USERHOMEDIR=""
USERSHELL=""
USERCOMMENT=""

if [ "$INTERACTIVE" -eq 1 ] ; then

echo "Add User:"
read -p "Enter GROUPID     : " GROUPID;
read -p "Enter GROUPNAME   : " GROUPNAME;
read -p "Enter USERID      : " USERID;
read -p "Enter USERNAME    : " USERNAME;

read -p "Enter USER HOME DIRECTORY ( Or hit enter for /home/$USERNAME ): " USERHOMEDIR;
if [ -z "$USERHOMEDIR" ]
then
        USERHOMEDIR="/home/${USERNAME}"
fi

read -p "Enter USERSHELL   : " USERSHELL;
read -p "Enter USERCOMMENT : " USERCOMMENT;

else

GROUPID=$1
GROUPNAME=$2
USERID=$3
USERNAME=$4
USERHOMEDIR=$5
USERSHELL=$6
USERCOMMENT=$7
fi

groupadd -g $GROUPID $GROUPNAME
cp -r /etc/skel $USERHOMEDIR
useradd -u $USERID -g $GROUPID -d "$USERHOMEDIR" -s "$USERSHELL" -c "$USERCOMMENT" $USERNAME
chown -R $USERNAME.$GROUPNAME $USERHOMEDIR
passwd $USERNAME

if [ "$INTERACTIVE" -eq 1 ] ; then
echo " "
echo -n "User:"
grep $USERNAME /etc/passwd
echo ""
echo -n "Group:"
grep $GROUPNAME /etc/group
echo ""
echo "$USERNAME home Dir $USERHOMEDIR long listing:"
ls -las $USERHOMEDIR
echo " "
echo "."
fi

The easiest way to install adduser.sh:

# wget http://kod.ipduh.com/lib/adduser.sh
# chmod 700 adduser.sh
# mv adduser.sh /bin

adduser.sh
