Hi all,
I need to run a perl script from Ruby and capture its output. I use the
following line in Ruby but it fails. Any input will be appreciated.
out=`perl c:\\Perl\\self\\back1\.pl`

maybe you can try to use an absolute path to 'perl'.

Define "fails". What happened?

Is this really the line you used? How about this instead:
out=`perl c:\\Perl\\self\\back1.pl`
Or, because I have no way to test your Windows syntax:
out=`perl c:/Perl/self/back1.pl`
Also, if Perl has been installed correctly and the Perl script is written
reasonably well, you shouldn't need the "perl" command in the line.
If these alternatives fail, you will have to run some tests, and work up to
the script.
Tests like this:
out = `perl -v`
See what this puts in the "out" variable.

Hi Paul,
Thank you very much.
They all work fine now. In order to capture the output
from Ruby I just need to "puts xxxx".
Another quick question: How to translate the codes
above using IO.popen. I read the related part of
IO.popen but I can't figure out how.
BTW I can't see your post and another post to my
question from the forum at Ruby talk. I think the
server might have some problems.
Once again thank you very much,
Li
