Unix file commands using PHP's system function

[ktsirig]

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' ?

Heya, ktsirig.

Might be a permissions issue. Try this instead:
[code=php]
copy('text.txt' , 'newtext.txt');
[/code]

Does the same thing, but without all the overhead of making a system() call. Plus, if anything goes wrong (such as 'permission denied'), PHP will throw a warning and let you know.
