    verify iso image before burn

    Hi Everyone
    I've downloaded two distros and want to check them before I burn them. I'm new to linux and don't really understand the terminal. So please explain it to me like a kids, and don't assume I know what you're talking about

    So, I looked online and found three ways to verify the image:

    1)SH1SUM
    2)MD5SUM
    3)manually mount
    su -c 'mount -o loop -t iso9660 <isofilename> <mountpoint>

    Neither of the iso images have a SH1SUM, or a MD5SUM file, and I don't really understand how to use the manual mount. For that matter, I'm not a 100% sure how to use the other two either, if I had them.

    Here are the two file from one of the downloads
    Pinguy_OS_12.04-shell-i686.iso.torrentPinguy_OS_12.04-shell-i686.iso


    When I tried the manual mount I typed in su -c 'mount -o loop -t iso9660 <Pinguy_OS_12.04-shell-i686.iso> <mountpoint>

    And this is what happened
    kojak@kojak-OptiPlex-760:~/Downloads$ su -c 'mount -o loop -t iso9660 <Pinguy_OS_12.04-shell-i686.iso> <mountpoint>
    >

    Obviously I've done something wrong, and I'm sure it is laughably simple, but I have no clue what it is. So can you give me a step by step explanation of how I can verify my iso image. Starting at the beginning

    Thanks

    The Pinguy_OS_12.04-shell-i686.iso md5sum is here: http://sourceforge.net/projects/ping...o.md5/download
    The md5sum "hash" itself is a long alphanumeric string; once you've downloaded it you can open it in a text editor.

    To actually check the md5sum of the iso, you need to run
    Code:
    md5sum Pinguy_OS_12.04-shell-i686.iso
    More info here: https://help.ubuntu.com/community/HowToMD5SUM

    Thanks oldos2er
    It worked, hurray. Feel like a linux pro now, lol. Well, maybe now, but getting there...slowly. One command line at a time

    Cheers
