steve tran wrote: Hello I am a beginner to perl and I have a question if I want to use system or open or backticks to execute a system command, like system("$cmd arg1"); ( with system for instance) and the $cmd which is a prog takes another program called in arg1 , and that program(arg1) requires STDIN, and I need to redirect the output from $cmd into a file how can I make both happen ? if I do system("$cmd arg1"); I can see my program waiting for input in STDOUT,but I cant capture the STDOUT to proces later but when I add system("$cmd arg1 >> out"); the program waits but the output from arg1 goes to out. Is there an easy way to accomplish both. I would really appreciate any help steve __________________________________ Yahoo! Mail for Mobile Take Yahoo! Mail with you!
