    Smile Optimized programming

    Hi All,
    Am new to linux forums .. I would like to know which one is more optimized among the below two,
    1) Fork + exec
    2) system() system call
    As per my knowledge fork+exec is better since i will be avoiding invocation of shell as the system() does. But still I would like to confirm it. Linux gurus out there, please help me.

    Thanks in advance

    You are correct. The fork/exec combination avoids the running of a shell, and is therefore faster (all other things being equal).
