Matthieu:
I tried your cgi script that process "ls -ail", however, it doesn't
work on TS-7250.
I got Read[] instead of Read[ls -ail].
Does your script run on host PC only?
Also, I heard python is more simpler and more powerful than Perl. Is
it true?
I would appreciate if anyone would give me some explaination.
