I have a Perl program which does something like below: #!perl

use strict;
use warnings;

my $exe = "C:\\project\\set_env_and_run.bat";

my $arg1 = "\\\\Server\\share\\folder1";    
my $arg2 = "D:\\output\\folder1";

my $cmd = "$exe \"$arg1\" \"$arg2\"";    
my $status = system("$cmd > c:\\tmp\\out.txt 2>&1");

print "$status\n";

I am calling this Perl code in an eval block. When invoked, i get the status printed as 0, but the batch file has not actually executed. What would be the reason for this? Any issue with the 'system' call coded above?

Thanks, Jits

You need to escape your backslashes inside of double quotes.

my $exe = "C:\\project\\set_env_and_run.bat";
...
my $status = system("$cmd > c:\\tmp\\out.txt 2>&1");

Sorry, i had put the sample code and missed escaping the backslashes! have corrected it above.

You can use proper (forward) slashes in file paths in Win32 perl? `my $exe = 'C:/project/set_env_and_run.bat';` will work quite nicely.

Are you sure the bat file isn't running. I have taken your code, fixed up the paths that don't exist on my machine. I get it to call the batch file

echo In myrun  1=%1  2=%2

And it writes the following to the output file

 In myrun  1="\\Server\share\folder1"  2="D:\output\folder1"
