# Executing a Client-Side Script-Based Verification

## What

The "verify" option of the fwGUI client application allows you to run a "verify" from the client programmatically.

## When/Why

We are going to use this option whenever we want to get "immediate" feedback from a client. For instance, as a post-installation script, calling a verify would immediately make the client report updated inventory rather than waiting (up to 24 hours, default) for the next "regular" verify.

## How

The verification is called as a command-line option to the fwGUI app on either a Windows or macOS client as follows:
