# 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:
**Windows Client****macOS Client**
**Path to fwGUI:**"C:\\Program Files (x86)\\FileWave" on 15.4.2 or lower and "C:\\Program Files\\FileWave\\client" on 15.5.0 or higher./usr/local/sbin/FileWave.app/Contents/Resources/
**App to call:**fwGUI.exefwGUI.app
**Command Line options:**--verify *Sends a verification (w/dialog by default...useful for troubleshooting)*--verify *Sends a verification (w/dialog by default...useful for troubleshooting)*
--silent *Used with --verify, sends verification without user dialog*--silent *Used with --verify, sends verification without user dialog*
**Script examples:****Windows Batch Example (FW 15.5.0+)** ```powershell @echo off "C:\Program Files\FileWave\client\fwGUI.exe" --verify --silent exit 0 ``` **macOS Bash Example** ```shell #!/bin/bash /usr/local/sbin/FileWave.app/Contents/Resources/fwGUI.app/Contents/MacOS/fwGUI --verify --silent exit 0 ```
