Does anyone know how I capture the value of an operation that defaults to STDOUT? For instance if I want to do something like
#!/usr/bin/perl -w
use strict; my $value = `perl -c someapp.cgi`; # prints to STDOUT print "Content-type: text/html\n\n"; print "Result: $value<BR>";
This obviously won't work because 'perl -c' directs the output away from my variable and into STDOUT. I'm thinking I might be able to capture that return value using IO::Handle or something of that nature but I'm not sure how. Can anyone help?
Sure you have a standard error. ;-)
perl -c 's output goes to STDERR not STDOUT. For this you will want to look at any of IPC::Open2, IPC::Open3, or simply adding a construct like:
2>&1
to the backtick command. HTH,
