Q&A  > programs and processes


I'm running perl on NT and can't get the output of my other programs thru the use of backticks.
Example: --------
#! c:\perl\bin\perl print "Hello World!";
--------- ---------<br> #! c:\perl\bin\perl.exe $output1 = ``; print "Option 1: ".$output1."\n"; open(STDOUT, ">output"); # from perlfaq8 system("");

Z:\test> Option 1: Z:\test> type output Z:\test>
---------- Any suggestions?

I had to add the -S switch to find the script file:

`perl -S`

Try changing your backticks to:

$output1 = `perl`;
I tried it, and it fixed the problem for me.

I had the same problem, and fixed it by prepending "perl " to the filename. My guess is that you don't have an association set up for the .PL file extension and the Perl executable.
