About Patch Command Line Tool

The Patch command line tool (CLT) is used to perform the installations/updates on a Mac. Typically this is controlled by the Patch Agent but you can also leverage the Patch CLT in scripted workflows or by running simple commands in Terminal.

Example Commands

Here are a few examples of how you can leverage the Patch CLT to perform some common tasks:

# Install the latest version of Dialpad
sudo patch install -s dialpad

# Install the latest version of Zoom and skip the version comparison
sudo patch install -s zoom-us --force

# Install two software titles that are dependent upon each other
sudo patch install -s cran-r -s r-studio --depends

# Update Cyberduck to the latest version if installed AND out-of-date,
# then perform a Jamf Pro Inventory Update after successful installation
sudo patch install -s cyberduck --update-only --recon

# Compare the installed version of Firefox with the Patch Catalog
# and exit abnormally if the installed version is out-of-date
sudo patch compare -s mozilla-firefox --fail

# Cache the install media for Slack, show progress of the download,
# and reveal in Finder
sudo patch cache -s slack --progress --reveal

# Install Google Chrome but use an alternative Alectrona Patch license
sudo patch install -s google-chrome --license YOUR-LICENSE-HERE

# List all of the software titles in the Patch Catalog
sudo patch list
