Using the Alternate Fetch and Check
===================================

Use these instructions to use the CentOS Fetch and Check programs if the main
`.com` web site is down.

-   The variable `GO` used below is two letters, upper-case. You use it
    twice, once to get the `do.sh` script and once to execute it. It must be
    upper-case. It must have the name `GO`.

-   Pick the correct course, term, and assignment number for the `do.sh` URL,
    do not use `00` as an assignment number below.

1.  Pick either **a** or **b** below (only pick one):

    a.  Get the `do.sh` script from the alternate `.org` site:

            $ GO=teaching.idallen.org
            $ url=http://$GO/cst8207/14w/notes/data/assignment00do.sh
            $ curl -A mozilla "$url" >do.sh
            $ fgrep -i 'error' do.sh    # make sure no errors (no output)
            $ head -n1 do.sh            # make sure it's a shell script
            #!/bin/sh -u

    b.  Get the `do.sh` script from the alternate `elearning` site:

            $ GO=elearning.algonquincollege.com/coursemat/alleni/idallen
            $ url=http://$GO/cst8207/14w/notes/data/assignment00do.sh
            $ curl -A mozilla "$url" >do.sh
            $ fgrep -i 'error' do.sh    # make sure no errors (no output)
            $ head -n1 do.sh            # make sure it's a shell script
            #!/bin/sh -u

2.  Pick either **a** or **b** below (only pick one) and use `$GO`:

    a.  **Run the script directly as the `root` user:** Use this only if you
        have not yet created your own sysadmin account:

            # whoami
            root
            # USER=abcd0001 GO=$GO sh do.sh        # your userid, not abcd0001

    b.  **Run the script using `su`:** Use this if you have already created
        your sysadmin account:

            $ echo "$USER"
            abcd0001                               # your userid, not abcd0001
            $ su -c "USER=$USER GO=$GO sh do.sh"   # must be double quotes, not single

**READ ALL THE WORDS. OH PLEASE, PLEASE, PLEASE READ ALL THE WORDS!**
