I run a farm of 150 Mac minis. I am trying to create a first run script that will set the host name and static IP based on the SN. I am getting an end of file error when I am trying to run it. Here is a small sample. Any help would be great!

!/bin/sh

serial=/usr/sbin/system_profiler SPHardwareDataType | /usr/bin/awk '/Serial Number (system)/ {print $NF}'

if test "$serial" == "C07M802Z4E825DY3J"
then

scutil --set ComputerName "qa-mac-1"

scutil --set LocalHostName "qa-mac-1"

networksetup -setproxyautodiscovery "Ethernet" on

networksetup -setmanual Ethernet 10.1.1.1 255.255.255.128 10.1.1.129

networksetup -setdnsservers Ethernet 10.2.76.98 10.2.76.97

networksetup -setsearchdomains Ethernet mycompany.com mycompanycorp.com us.mycompany.com

else

if test "$serial" == "C07M803JDLSY3J"
then

scutil --set ComputerName "qa-mac-2"

scutil --set LocalHostName "qa-mac-2"

networksetup -setproxyautodiscovery "Ethernet" on

networksetup -setmanual Ethernet 10.1.1.2 255.255.255.128 10.1.1.129

networksetup -setdnsservers Ethernet 10.2.76.98 10.2.76.97

networksetup -setsearchdomains Ethernet mycompany.com mycompanycorp.com us.mycompany.com

if test "$serial" == "C0737951JDLSY3J"
then

scutil --set ComputerName "qa-mac-3"

scutil --set LocalHostName "qa-mac-3"

networksetup -setproxyautodiscovery "Ethernet" on

networksetup -setmanual Ethernet 10.1.1.2 255.255.255.128 10.1.1.129

networksetup -setdnsservers Ethernet 10.2.76.98 10.2.76.97

networksetup -setsearchdomains Ethernet mycompany.com mycompanycorp.com us.mycompany.com

Use elif instead of else if. Otherwise you are creating a bunch if blocks, but you are not closing the if blocks with fi statements. Try writing it like this:

#!/bin/sh

if [ $serial == "<<SERIAL1>>" ]; then 
    <<code for SERIAL1>>
elif [ $serial == "<<SERIAL2>>" ]; then
    <<code for SERIAL2>>
elif [ $serial == "<<SERIAL3>>" ]; then
    .
    .
    .
fi 
exit 0

If you need to look for errors in your code, try Shellcheck. It can help identify errors in your code.
