Bash Script to: Rename Computer and Bind to AD (No User Interaction) and User Interaction

[NickGuru]

Here is a script that i use to rename computers remotely via Jamf. Many computers were not following our standard naming convention, such as computers named "Admin MacBook Pro", etc..

#!/bin/sh
serial=`/usr/sbin/system_profiler SPHardwareDataType | /usr/bin/awk '/Serial Number (system)/ {print $NF}'`
/usr/sbin/scutil --set ComputerName "CRP${serial}"
/usr/sbin/scutil --set LocalHostName "CRP${serial}"
/usr/sbin/scutil --set HostName "CRP${serial}"
sudo dsconfigad -force -remove -u YourMacBindingAccount -p YourBindingAccountPassword
sudo jamf policy -id 482

#### or with user interaction use this script:

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

function machinename () {
    osascript <<EOT
        tell application "Finder"
            activate
            set nameentry to text returned of (display dialog "
            Please name your computer. 
            The naming convention is the 3 letter 
            dept name,
            followed by the serial number.

            Example:
            CRP${base}${serial}

            The serial number for this Mac is:
            ${base}${serial}" default answer "" with icon 2)
            end tell
EOT
}

function renameComputer(){
    echo "The New Computer name is: $ComputerName"
    scutil --set HostName $ComputerName
    scutil --set LocalHostName $ComputerName
    scutil --set ComputerName $ComputerName

    echo Rename Successful
}

ComputerName=$(machinename) 
renameComputer
sudo dsconfigad -force -remove -u YourMacBindingAccount -p BindingAccountPassword
sudo jamf policy -id 482
sudo jamf manage
sudo jamf recon
sudo /usr/local/jamf/bin/jamf displayMessage -message "To Join your Computer to our Corp Domain, please re-start your computer."
exit 0

@nsantoro two quick things. First, you may want to re-post that using the "script" tags (the >_ icon above) so that the script is not messed up by formatting.

Second, instead of using system_profiler to get the serial number of the machine, you may want to move over to using ioreg as it is less resource heavy and quicker:

ioreg -l | awk '/IOPlatformSerialNumber/ { print $4;}'

[MadPossum · Accepted solution]

If the reason you're using system_profiler is to avoid the double quotes returned by @nsantoro example you can remove them by piping the output to sed like this.

ioreg -l | awk '/IOPlatformSerialNumber/ { print $4;}' | sed -e 's/^"//' -e 's/"$//'

@stevewood thanks.

[NickGuru]

thank you @MadPossum & @stevewood I just made changes to my scripts and it works quicker.

#bin/sh
serial=`ioreg -l | awk '/IOPlatformSerialNumber/ { print $4;}' | sed -e 's/^"//' -e 's/"$//'`

Hey @Nsantoro,
Question for you. Your script refers to this policy in your JSS:

sudo jamf policy -id 482

What is this policy being called doing? Is policy 482 an AD binding/unbinding action you've setup or something? (I'm looking to use your script here in our environment...it would help me as well..)

Thanks.

[NickGuru]

@steve.summers the policy call is pointing to another policy that i have in place which is a directory bind policy. Using Jamf Builtin function under options/ Directory Bindings.)

No User Interaction:

1. Rename Computer name to proper naming convention
2. Force Unbinds
3. Calls to a Jamf Policy (mine is 482) - which Binds the Mac to the Domain.

#!/bin/sh
serial=`ioreg -l | awk '/IOPlatformSerialNumber/ { print $4;}' | sed -e 's/^"//' -e 's/"$//'`
/usr/sbin/scutil --set ComputerName "CRP${serial}"
/usr/sbin/scutil --set LocalHostName "CRP${serial}"
/usr/sbin/scutil --set HostName "CRP${serial}"
sudo dsconfigad -force -remove -u YourMacBindingAccount -p YourBindingAccountPassword
sudo jamf policy -id 482

This Script has user interaction.

I made this available to our onsite support techs: to bind Macs to the domain.

#!/bin/sh
serial=`ioreg -l | awk '/IOPlatformSerialNumber/ { print $4;}' | sed -e 's/^"//' -e 's/"$//'``

function machinename () {
    osascript <<EOT
        tell application "Finder"
            activate
            set nameentry to text returned of (display dialog "
            Please name your computer. 
            The naming convention is the 3 letter 
            dept name,
            followed by the serial number.

            Example:

            The serial number for this Mac is:

            end tell
EOT
}

function renameComputer(){
    echo "The New Computer name is: $ComputerName"
    scutil --set HostName $ComputerName
    scutil --set LocalHostName $ComputerName
    scutil --set ComputerName $ComputerName

    echo Rename Successful
}

ComputerName=$(machinename) 
renameComputer
sudo dsconfigad -force -remove -u YourMacBindingAccount -p BindingAccountPassword
sudo jamf policy -id 482
sudo jamf manage
sudo jamf recon
sudo /usr/local/jamf/bin/jamf displayMessage -message "To Join your Computer to our Corp Domain, please re-start your computer."
exit 0

I tried both commands to get the serial number:
ioreg -l | awk '/IOPlatformSerialNumber/ { print $4;}' | sed -e 's/^"//' -e 's/"$//'
/usr/sbin/system_profiler SPHardwareDataType | /usr/bin/awk '/Serial Number (system)/ {print $NF}'

My experience is the system_profiler method feels actually quite faster than ioreg.
