[KB3417] ESET Command Line Scanner Parameters (ecls.exe)

Issue

Solution

The ESET Security On-demand scanner can be initiated from both the product and the command line. Command line scanning is useful if your computer is currently only operational in Safe Mode or if you are a network administrator and want to initiate scanning from an external application.

Location of ECLS scanner

The scanner (filename: ecls.exe) is located in C:\Program Files\ESET\ESET Security.

To use the scanner, open a Command Prompt and reference the full directory path to the scanner, followed by the list of objects to scan. Additional parameters (see Scanner options) can be appended to the command line to further modify your scan.

Review the Online Help page for more information on ESET Command Line Scanner.


Command line examples

Example 1

Example 1 commands your ESET product to run a scan with automatic scan settings, and shows the status bar of the scan while running and create a scan log file:

"C:\Program Files\ESET\ESET Security\ecls.exe" /base-dir="C:\Program Files\ESET\ESET Security\Modules" /auto /log-file=c:\ecls.txt /aind

Error notifications

When performing an On-demand computer scan, you may see multiple error notifications in the Scan log.

Example 2

Example 2 creates a batch file that commands the ESET Endpoint (version 5) product to shutdown when a scan finishes:

@echo off
“C:\Program Files\ESET\ESET Security\ecls.exe” /base-dir=”C:\Program Files\ESET\ESET Security\Modules” /auto /aind /quarantine /memory /log-file=c:\ESET_scanlog.txt
shutdown /f /s /t 00
