How to redirect the Perl script output from command issued in windows command prompt to text file

Question

I am new to Perl and I am executing a .pl file within the CommandPrompt dialog box in Windows 7 by doing the following:

c:\perlscripts\runReport.pl 5

In addition to seeing the output in the CommandPrompt dialog box is there a way that I can redirect the output to a text file as well?

Any help/direction would be appreciated. Regards.

If you append '> filename.txt' to your line, it will output the results to a file instead. If you want to do both, there is apparently the wintee utility at http://code.google.com/p/wintee/. If it is similar to UNIX tee, than using it should only require you to append '| tee filename.txt' to your line.

Thanks for your quick response. I actually tried that but here is the issue. In the commandprompt dialog box I'm showing a stack trace that is printing out but it does not print to the text file. Any suggestions? Thanks.

@Melinda It's probably going to STDERR, so you could send both to the same place by appending '2>&1' to the end of your line.

@Melinda: It's not a dialogue box - it's a window.

Thanks Borodin. I appreciate the clarification.

@Melinda, it would actually be 'runReport.pl 4 > melinda.txt 2>&1', but if you are going to use tee like tohava pointed out, it would be 'runReport 4 | tee melinda.txt 2>&1'

Instead of printing the output in command line. You can write the output in a file.

# Opening file to write the program's output. 
open(FH, ">myFile.txt") or die "Cannot open myFile.txt";

# include module to dump output.
use Data::Dumper;
print FH Dumper(@output);

close FH;

Else you can write like this:

perl my_script.pl > myFile.txt

You should recommend using 3-arg open instead of 2-arg. modernperlbooks.com/mt/2010/04/…
