Problems running a script "as user" in policy and using file with spaces in command

I'm trying to write a generic script to set default app for a document type e.g. PDF using https://github.com/Lord-Kamina/SwiftDefaultApps/releases

This works from a policy where $4 is set to: /Applications/Nitro\\ PDF\\ Pro.app
and $5 is set to com.adobe.pdf - but in the script I explicitly ignore $4 and set application_name

 

 

#!/bin/bash # SetDefaultApplication.bash #application_name="$4" application_name=/Applications/Nitro\\ PDF\\ Pro.app echo $application_name # e.g. /Applications/Nitro\\ PDF\\ Pro.app uti_name="$5" # e.g. com.adobe.pdf currentUser=$(stat -f%Su /dev/console) # setHandler sudo -u $currentUser /usr/local/libexec/swda setHandler --application "$application_name" --UTI $uti_name

 

 

 

and in the policy I see the output as:

Script result: /Applications/Nitro PDF Pro.app
SwiftDefaultApps SUCCESS: Default handler has succesfully changed to com.gonitro.NitroPDFPro

 

But, if I try and use $4

 

 

#!/bin/bash # SetDefaultApplication.bash application_name="$4" #application_name=/Applications/Nitro\\ PDF\\ Pro.app echo $application_name # e.g. /Applications/Nitro\\ PDF\\ Pro.app uti_name="$5" # e.g. com.adobe.pdf currentUser=$(stat -f%Su /dev/console) # setHandler sudo -u $currentUser /usr/local/libexec/swda setHandler --application "$application_name" --UTI $uti_name

 


I get an error from the policy

Script result: /Applications/Nitro\\ PDF\\ Pro.app
SwiftDefaultApps ERROR -10814: No application found for /Applications/Nitro\\ PDF\\ Pro.app

 

and yet on that machine, I can run the script as root

dep54592:lab root# ./SetDefaultApplication.bash 1 2 3 /Applications/Nitro\\ PDF\\ Pro.app com.adobe.pdf
/Applications/Nitro PDF Pro.app
SwiftDefaultApps SUCCESS: Default handler has succesfully changed to com.gonitro.NitroPDFPro


Just wondering if anyone can see where I'm going wrong?

@dlondon Are you using /Applications/Nitro\\ PDF\\ Pro.app or just /Applications/Nitro PDF Pro.app as Parameter 4 when calling your script from Jamf Pro? If the former, what happens when you try the latter?

    When using application_name="$4" in the script, it implies that the variable would be passed as double quoted, in which case you don't want to use a string for $4 using the backslashes. "/Applications/Nitro\\ PDF\\ Pro.app" is not a valid path and the error is indicating as such. So, basically the same thing that @sdagley is implying in their post.

    So here's a cleaner copy of the final script with credits and explanations

    #!/bin/bash # SetDefaultApplication.bash # David London # 2022-09-01 # With help from sdagley (Steve Dagley) and mm2270 (Mike Morales) # in https://community.jamf.com/t5/jamf-pro/problems-running-a-script-quot-as-user-quot-in-policy-and-using/m-p/272752#M248439 # Initial direction from the end of this post on using swda https://community.jamf.com/t5/jamf-pro/setting-default-open-with-app/m-p/11473 # This is a generic script that uses the command line component of SwiftDefaultApps # available at https://github.com/Lord-Kamina/SwiftDefaultApps/releases # This script will set the default app for a file type for the currently logged in user # The script is intended to be used in a policy and a copy of the command line component of SwiftDefaultApps has been placed in a known location # In this case the known location of swda is /usr/local/libexec/ but it could be anywhere e.g. /tmp # For me, I just package up swda in /usr/local/libexec and deploy that first before the script in the policy # grab $4 e.g. /Applications/Nitro PDF Pro.app application_name="$4" # grab $5 e.g. com.adobe.pdf uti_name="$5" # get the current user currentUser=$(stat -f%Su /dev/console) # setHandler sudo -u $currentUser /usr/local/libexec/swda setHandler --application "$application_name" --UTI $uti_name


    and in Jamf Pro the parameter tab looks like this
