echo typically is not a program. It is a command in the CMD.exe or COMMAND.com programs. $output=exec("cmd -c echo hello"); //should produce the desired effect. Why piping output to a file changes this fact, is beyond me.

The definition of exec() is that it uses popen() which starts a shell automatically. Anyway, the problem was very Windows specific and doesn't have anything to do with the syntax he used.

right now we are executing the programm direct, without creating a console. maybe we should manage a list of internal commands, like echo, dir, copy,... and create a console for them...

no it's a bad idea, i'll shut up :) cmd line parsing is a pretty bad idea, and the user is better of doing passthru( getenv("COMSPEC") . " /c echo")

Ouch but then the fix isn't popen() compatible. Andi
