process redirection

[pavan_gpk]

HI, I just want to know how to redirect my 'system' function output to a specified path or directory.. i mean.. i have one executable file and generates a file with .cab or .exe. i used 'system' function to execute the file and generating the specified file in my current directory..but i want to generate those files in my specified path.. thanks & regards, pavan.

What happens if you change directories first?

...putting that into code and showing how to redirect the other output as well:-

system( "cd $mydir; $command > cmd.log 2>\&1" );

Hi if i change my directory first 'system' cant fetch the executable file in that directory and giving error.. let me explain more clearly what exactly i am looking for i need to run 'build.exe' that generates .cab's/.exe's files in current directory not to STDOUT.but i need to generate those files in the specfied path or directory that i specify.. thanks pavan..

system function only returns the exit status of the command; if you want to capture the output, you should use backticks:

$result = `command`;

Then, you can write this output to wherever you want it with something like this:

open OUTFILE, "> /path/to/outfile.txt";
print OUTFILE $result;
close OUTFILE;

 

Alternately, if you do not want to process the output in Perl, you can just do something like this:

system("command > /path/to/result.txt");

However, in this case you probably wouldn't need to use Perl for it at all...

but it's his executable that is generating the cab/exe file, it's not being returned on STDOUT. If this was the problem, he'd be complaining that he wasn't generating cab's/exe's at all, not just that they were in the wrong place.

He needs to change directory as per pbeckingham suggests and anonymized user 468275 demonstrates. (or pass an output file parameter to his exe, if it has one)
