Subject: [SLE] Problem with script erasing first possible space from a line

    Hi

    Whe I do following:
    ps ax|grep 'home-main'|grep tun|cut -f1 -d' '
    I get the process ID of the line:
    31328 ? S< 0:00 vtund[c]: home-main tun tun1

    But, if there is a space before the process-ID (ID under 9999), then the last
    script command "cut -f1 -d' '" does not work, because it will see the first
    space as a delimiter.

    How can I erase the leading space(s) from that line, so the "cut" command
    would work with space in front of the line?

    Or better yet, is there another (better?) way to get a process-id with program
    name and its parameter-line

    Jaska.
