The 'use lib' logic happens in the pre-compile stage, so one cannot use normal 'if' logic to use a particular INC. Instead, just make sure that best dir is added to 'use lib' last since it prepends to INC.
LANforge Perl Scripts
This is a collection of scripts and scripting libraries designed to work
with LANforge systems. On your LANforge system, these scripts are
typically installed into /home/lanforge/scripts. The LANforge/ sub directory holds
the perl modules (.pm files) that are common to the perl scripts.
Commonly Used
The lf_*.pl scripts are typically more complete and general purpose
scripts, though some are ancient and very specific. In particular,
these scripts are more modern and may be a good place to start:
| Name | Purpose |
|---|---|
lf_portmod.pl |
Query and update physical and virtual ports |
lf_firemod.pl |
Query and update connections (Layer 3) |
lf_icemod.pl |
Query and update WAN links and impairments |
lf_attenmod.pl |
Query and update CT70X programmable attenuators |
lf_associate_ap.pl |
Query and update wifi stations |
The lf_wifi_rest_example.pl script shows how one might call the other scripts from
within a script.
Examples and Documents
Read more examples in the scripting LANforge cookbook.
