In the subject, you are asking the wrong question! You don't want to use shell commands, that is invoke other application, in your application. You really want to get the cpu and memory usage statistics and presume a solution, that is wrong. You don't want to invoke top, free and vmstat -- you want to read the information from the source they do. Now, that source is in procfs (the thing usually mounted on /proc). ------------------------------------------------------------------------------- Jan 'Bulb' Hudec <bulb@xxxxxx>
