the > in UNIX

Hi all!
I am confused as to how an old-good UNIX command, like

cat text.txt > new_tex.txt

can be used in PHP.
I tried
system (" cat text.txt > new_text.txt");

but it didn't work, the file new_text.txt was left blank.
Am I doing something wrong with the > ???
Must I use something else instead of 'system' ?

why don't you use fopen, fread and fwrite to read and write from a file, it's more 'php' that way.

Fine for the lounge. It's better not to just toss out misleading and undiluted junk in a technical thread. Pipes and redirection aren't the same thing.
