Deployment script and command reference

How the Windows script works

The user detection script for Windows:

• Uses the device's operating system to determine the most recent logged-on username.
• Calculates the typical home directory for that username.

The user detection script then reports these two values to a standard output.

Tips to create a custom Windows script

Create a custom script and paste your script into your deployment policy. If you need help, contact your Customer Success Manager (CSM) for enterprise support.

When creating your custom script, be aware of the following:

• Every script must end by echoing values for two variables.

  echo C42_USERNAME=<value>
  echo C42_USER_HOME=<value>

• In the Code42 cloud, usernames must be email addresses.

  echo C42_USERNAME=%current_user%@example.com

• Optionally, you can also specify the the organization for the user. Use the registration key for the organization. If the organization is not defined, the user registers to the organization specified in the deployment policy.

  echo C42_ORG_REG_KEY=<value>

• You must provide values. Null values and empty strings will not work.
• If you cannot write a script to provide a workable value, write a message for the username field of the Code42 app sign in dialog, for example:

  echo C42_USERNAME=Enter name and click Sign in

• The values cannot include either single (') or double (") quotation marks.

Explorer.exe with ADSI domain lookup script

Professional Services filename: UserDetect_ADSIDomainLookup.bat

The following script detects users running explorer.exe and performs an Active Directory Service Interfaces (ADSI) search against Active Directory to obtain the mail attribute for the users. The script sets the home directory by adding the username to the \Users directory path in Windows. You can adjust this script to look for any attribute in Active Directory, such as userPrincipalName or custom attributes. This script requires an active connection to a Windows domain and PowerShell v.4.0 or later.

How the Mac script works

The user detection script for Mac:

• Uses the device's operating system to determine the most recent logged-on username.
• Calculates the typical home directory for that username.

The detection script then reports these two values to a standard output.

/usr/bin/python -c 'from SystemConfiguration import SCDynamicStoreCopyConsoleUser; import sys; username = (SCDynamicStoreCopyConsoleUser(None, None, None) or [None])[0]; username = [username,""][username in [u"loginwindow", None, u""]]; sys.stdout.write(username + "\n");'

echo "show State:/Users/ConsoleUser" | scutil | awk '/Name :/ && ! /loginwindow/ { print $3 }'

Tips to create a custom Mac script

Create a custom script and paste your script into your deployment policy. If you need help, contact your Customer Success Manager (CSM) for enterprise support.

When creating your custom script, be aware of the following:

• Every script must end by echoing values for two variables:

  echo "C42_USERNAME=<value>"
  echo "C42_USER_HOME=<value>"
  

• In the Code42 cloud, usernames must be email addresses.

  echo "C42_USERNAME=${user}@example.com"
  

• Optionally, you can also specify the the organization for the user. Use the registration key for the organization. If the organization is not defined, the user registers to the organization specified in the deployment policy.

  echo C42_ORG_REG_KEY=<value>

• You must provide values. Null values and empty strings will not work.
• If you cannot write a script to provide a workable value, write a message for the username field of the Code42 app sign in dialog, for example:

  echo "C42_USERNAME=Enter name and click Sign in"
  

• The values cannot include either single (') or double (") quotation marks.

Prompt for email script

Professional Services filename: Email_prompt_for_email.sh

The following script creates a pop-up notification at Code42 app installation time prompting users to input their email address, which automatically registers the users in Code42 and starts backup. This script provides an alternative when no other scripts work and you want the end user to manually input their email address.

If you are deploying Code42 app version 8.0 or earlier, replace the line  tell application "Code42" with tell application "CrashPlan" in the sample below.

Jamf plist script

Professional Services filename: macuserdetection-plist.sh

The following script is helpful if you use Jamf for device management. The script places a plist on the local machine that is populated with the username associated with the device from Jamf. This script is a good option if you have a username associated with a specific device in JAMF, but you do not have assurance that the usernames on the local device match the username part of the email address. This script requires additional setup in Jamf.

To use this script:

1. Place the script into your deployment policy.
   You may need to update the script depending on your Jamf version and configuration. Earlier versions of Jamf put the plist in ~/Library/Preferences/, but later versions put it in /Library/Managed Preferences/.
2. In Jamf, create a new configuration profile or edit an existing one.
3. Go to Custom Settings (or Application & Custom Settings, depending on your Jamf version), and upload the following com.code42.email.plist file.
   This is a sample plist file. If you prefer, you can create your own, as long as the EMAIL variable is present as a key that matches what the deployment policy is set up to read.

    <string>$EMAIL</string>
</dict>
</plist>

4. Scope the Privacy Preferences Policy Control (PPPC) to the users.
   Use appropriate scoping. Whether you scope to users or machines depends on your environment. JAMF must have an email on file for whatever you scope the profile to.
5. Deploy as normal.

Mac deploy.properties file location

When the Code42 app installer runs on Mac, it looks for the deploy.properties file in three locations, in the following order:

1. In the disk image, typically in:
   • Version 8.2 and later: /Volumes/Code42
   • Version 8.0 and earlier: /Volumes/Code42CrashPlan
2. In a Jamf Pro temp directory:
   • Version 8.2 and later: /tmp/mountpt/Code42
   • Version 8.0 and earlier: /tmp/mountpt/Code42CrashPlan
3. (Recommended location) In the directory /Library/Application Support/CrashPlan
   Installations for a single user use ~/Library rather than /Library.

Location 1, the disk image

Adding deploy.properties to the installer disk image is recommended for users starting an install manually, by clicking on the *.dmg file.

Test this option:
Not all deployment software mounts the disk image in the same location, making deploy.properties in the disk image hard to find.

Add deploy.properties to the disk image as follows:

1. Make a writable copy of the disk image.
2. Mount the writable copy.
3. Copy deploy.properties to the new image's root directory.
4. Unmount the image.
5. Return the image to the read-only state.

The following example shows the commands needed to add the deploy.properties file to the disk image. This example is for Code42 app version 8.2 and later. For Code42 app version 8.0 and earlier, the installer and volume name use Code42CrashPlan instead of Code42:

hdiutil attach C42_n.n.n_w.dmg
cp deploy.properties /Volumes/Code42/deploy.properties
hdiutil detach /Volumes/Code42
hdiutil convert -format UDRO C42_n.n.n_w.dmg -o C42_n.n.n_ro.dmg

Location 3, Application Support (recommended) 

For deployment with most software management tools, including Jamf Pro, Code42 recommends storing the file here:
/Library/Application Support/CrashPlan/deploy.properties

To install for a single user, rather than all users of a device, use  ~/Library rather than /Library.

To create the directory and write the file, we recommend a bash script like the following where you replace <deploy.properties> with the text from your deploy.properties file.

#!/bin/bash
mkdir -p /Library/Application\ Support/CrashPlan
echo "<deploy.properties>" > /Library/Application\ Support/CrashPlan/deploy.properties

Tips to create a custom Linux script

Create a custom script and paste your script into your deployment policy. If you need help, contact your Customer Success Manager (CSM) for enterprise support.

When creating your custom script, be aware of the following:

• Every script must end by echoing values for two variables:

  echo C42_USERNAME=<value>;
  echo C42_USER_HOME=<value>;
  

• In the Code42 cloud, usernames must be email addresses.
• Optionally, you can also specify the the organization for the user. Use the registration key for the organization. If the organization is not defined, the user registers to the organization specified in the deployment policy.

  echo C42_ORG_REG_KEY=<value>

• You must provide values. Null values and empty strings will not work.
• If you cannot write a script to provide a workable value, write a message for the username field of the Code42 app sign in dialog, for example:

  echo C42_USERNAME=Enter name and click Sign in;
  

• The values cannot include either single (') or double (") quotation marks.
