Best practice question - How to check for entware/3rd party script.

[Swinson]

Is there any preferred method for validating that a 3rd party script is installed?
Should I just check that the script/file exists or should I do something more robust in case the file is empty or really out of date?

When in doubt, do what amtm does: check for the existence of the primary Addon script, and check for the existence of /opt/bin/opkg.

If you require tighter integration with a particular script, check with the author on the best way to determine if it’s truly installed and functional.

Okay Thanks! I figured a check for the existence of a file would suffice but I wanted to ask because I learning more and more everyday how little I know .
I appreciate your feedback. I’ll refer to amtm for an example.
