Script to change computer name

[tomasitow77]

Hi all,

I just migrated from JamfNow to JamfPro and Im very new here. 

Im addressing computer's name by a Smart Group with a policy to execute this Script, which is not working for me.

Basically I want to use the prefix MBP or MBA, depending on the model, following the SN of the laptop. 

Any advice or help will be highly value. 

#!/bin/sh

# Get laptop model
model=$(system_profiler SPHardwareDataType | awk '/Model Identifier/ {print $3}')

# Get Serial Number
serial=$(system_profiler SPHardwareDataType | grep Serial | awk '{ print $4 }')

# Assign a prefix
if echo "$model" | grep -q "MacBookPro"; then
    prefix="MBP"
elif echo "$model" | grep -q "MacBookAir"; then
    prefix="MBA"
else
    prefix="APPLE"
fi

# Generate computername
computerName="$prefix-$serial"
echo "$computerName"

# Rename computer
scutil --set ComputerName "$computerName"
sleep 5
scutil --set HostName "$computerName"
sleep 5
scutil --set LocalHostName "$computerName"
sleep 5

echo "Computer renamed to $computerName"

# Clean caché and push an inventory sync
dscacheutil -flushcache
/usr/local/bin/jamf recon

Thanks a lot,

We just match the hostname of the device to the Serial Number, and below is the script I use.

It should not be difficult to add a function and if statements to add a prefix to the new hostname based on the device model from system profiler, something like the command below. Once you have MacBook Pro or MacBook Air, write an if to run the correct commands to put MBA or MBP in front of the hostname depending on the result of the command.

/usr/sbin/system_profiler SPHardwareDataType | grep "Model Name"

Something like this?

#!/bin/bash

OLDCOMPNAME=`/usr/sbin/scutil --get ComputerName`
sudo /System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/Resources/kickstart -configure -computerinfo -set1 -1 "${OLDCOMPNAME}"
PREFIX="MBP"
SERIAL=`system_profiler SPHardwareDataType | grep "r (system)" | awk '{ print $4}'`
HOSTNAME="${PREFIX}${SERIAL}"
sudo /usr/sbin/scutil --set ComputerName "${HOSTNAME}"
sudo /usr/sbin/scutil --set LocalHostName "${HOSTNAME}"

exit 0

Somebody from JAMF Nation provided this script. It changes the name of the Mac to the Serial Number.

!/bin/bash

serialNumber=$(system_profiler SPHardwareDataType | awk '/Serial/ {print $4}')

echo $serialNumber

sudo jamf setComputerName -name $serialNumber

sudo jamf recon

Faster way to get the Mac’s serial:

serial=$(ioreg -c IOPlatformExpertDevice -d 2 | awk -F\" '/IOPlatformSerialNumber/{print $(NF-1)}')

Thanks everybody, 

Here is the final result, if you want to use it anytime. 

#!/bin/sh

# Get laptop model
model=$(system_profiler SPHardwareDataType | grep Model | awk '{print $4}')

# Get SN
serial=$(system_profiler SPHardwareDataType | grep Serial | awk '{ print $4 }')

# Assign a prefix
if echo "$model" | grep -q "Pro"; then
prefix="MBP"
elif echo "$model" | grep -q "Air"; then
prefix="MBA"
else
prefix="Apple"
fi

# Generate computername
computerName="$prefix-$serial"
echo "$computerName"

# Rename computer
scutil --set ComputerName "$computerName"
sleep 5
scutil --set HostName "$computerName"
sleep 5
scutil --set LocalHostName "$computerName"
sleep 5

echo "Equipo renombrado a $computerName"

Thank you very much. I shortened the script but it was a great start for me as a beginner.
