macOS Patching

Hello,

I am currently attempting to write a script to patch a Mac computer.

This is my script:

#!/bin/bash todayDate=$(date "+%d.%m.%Y") patchingLogFile=patching_"$todayDate" exec > /tmp/"$patchingLogFile".txt 2>&1 echo "Part 1:0 log file has been created" computerMacOSVersionFirstValue=$( sw_vers -productVersion | /usr/bin/cut -d. -f1 ) macOSVersionUpdate="11.7.2" if [ "$computerMacOSVersionFirstValue" == "11" ] ; then softwareupdate -R --fetch-full-installer --full-installer-version 'macOS $macOSVersionUpdate' 2>&1 else echo "Don't do the update" fi

The problem I am getting, is that when I look in the log file, I get this return:

Scanning for macOS $macOSVersionUpdate installer

Install failed with error: Update not found

 But if I run the code:

softwareupdate -R --fetch-full-installer --full-installer-version 'macOS 11.7.2' 2>&1

Then the computer will update with the intended version.
I don't know what I am doing wrong! Can a scripting guru help me please? That would be greatly appreciated.

Thank you

and add after shebang

set -x 

while testing to debug and get output.. 

double quotes.. not single.. your not expanding the variable with single quotes hence the variable in the output

    Wow!! The double quote did resolve my issue with the variable. Thank you!

    But I don't understand what you mean when you wrote:

    I have updated my script with the double quote:

    #!/bin/bash todayDate=$(date "+%d.%m.%Y") patchingLogFile=patching_"$todayDate" exec > /tmp/"$patchingLogFile".txt 2>&1 echo "Part 1:0 log file has been created" computerMacOSVersionFirstValue=$( sw_vers -productVersion | /usr/bin/cut -d. -f1 ) macOSVersionUpdate="11.7.2" if [ "$computerMacOSVersionFirstValue" == "11" ] ; then softwareupdate -R --fetch-full-installer --full-installer-version "macOS $macOSVersionUpdate" 2>&1 else echo "Don't do the update" fi

    And the result on the text file is:

    Scanning for macOS 11.7.2 installer

    Install failed with error: Update not found

    I am going to understand why the update didn't work, nevertheless, a very big step forward, so thank you very much for your help!! ✌️

    see here https://stackoverflow.com/questions/36273665/what-does-set-x-do 

    when scripting it can be handy to add this at the start of your script.. it outputs the process of the script.. so you can see what's going on.. once your happy with it working.. you can remove it..

    I don't think using "macOS <version>" is the correct syntax. I've never done it that way. I've always just used the version only and not included the "macOS" part when using the --fetch-full-installer flag.

    I would run

    sudo softwareupdate --list-full-installers

    to see what it returns for full versions and only pick the numerical value after "Version: "

    Thank you for your response and your help.

    I have tried the fllowing command changing it slightly, and th result was always the same:

    For

     

    softwareupdate -R --fetch-full-installer --full-installer-version "macOS $macOSVersionUpdate" 2>&1

     

    I got:
    Scanning for macOS 11.7.2 installer

    For:

     

    softwareupdate -R --fetch-full-installer --full-installer-version "macOS Big Sur $macOSVersionUpdate" 2>&1

     

    I got:
    Scanning for macOS Big Sur 11.7.2 installer

    and for:

     

    softwareupdate -R --fetch-full-installer --full-installer-version "$macOSVersionUpdate" 2>&1

     

    I got:
    Scanning for 11.7.2 installer

    And for all 3 attempts, I got the following return message:

    Install failed with error: Update not found

    Which is odd because when you run:

    sudo softwareupdate --list-full-installers

    You get:

    Finding available software Software Update found the following full installers: * Title: macOS Monterey, Version: 12.6.3, Size: 12406118533K * Title: macOS Monterey, Version: 12.6.2, Size: 12395078361K * Title: macOS Monterey, Version: 12.6.1, Size: 12399095056K * Title: macOS Big Sur, Version: 11.7.3, Size: 12410109599K * Title: macOS Big Sur, Version: 11.7.2, Size: 12410170728K * Title: macOS Big Sur, Version: 11.7.1, Size: 12410109410K * Title: macOS Big Sur, Version: 11.6.6, Size: 12412173576K * Title: macOS Big Sur, Version: 11.6.5, Size: 12412317772K * Title: macOS Big Sur, Version: 11.6.4, Size: 12439328867K * Title: macOS Big Sur, Version: 11.6.3, Size: 12435122667K * Title: macOS Big Sur, Version: 11.6.2, Size: 12433351292K * Title: macOS Big Sur, Version: 11.6.1, Size: 12428472512K * Title: macOS Big Sur, Version: 11.5.2, Size: 12440916552K * Title: macOS Catalina, Version: 10.15.7, Size: 8248985973K * Title: macOS Catalina, Version: 10.15.7, Size: 8248854894K * Title: macOS Catalina, Version: 10.15.6, Size: 8248781171K * Title: macOS Mojave, Version: 10.14.6, Size: 6038419486K * Title: macOS High Sierra, Version: 10.13.6, Size: 5221689433K
