ya u are right, i tried

system("(cd path/to/perl && ./myscript.pl) > output.file 2>&1")

the program that i am calling from my ruby script is a perl script

but there is one more problem, i am using this ruby script with screens
and this system function call just happens to capture output from some 
other screens as well.. dunno whats the reason..


Thanks,
Chandan.
