Getting Help

  • Where can I find system documentation?

    There is the GNU info system. For example if you are curious about libc try:

    info libc

    For quick answers the man pages are sometimes better.

    man printf

    The most useful man command is "q" (to quit)

    The most useful man option is "-k" for "keyword" For example

    man -k passwd | more

    ...gives you

    chage (1) - change user password expiry information
    chpasswd (8) - update password file in batch
    crypt (3) - password and data encryption
    d_passwd (5) - The dialup shell password file
    dpasswd (8) - change dialup password
    endpwent (3) - get password file entry
    expiry (1) - check and enforce password expiration policy
    fgetpwent (3) - get password file entry
    getpass (3) - get a password
    getpw (3) - Re-construct password line entry
    getpwent (3) - get password file entry
    getpwnam (3) - get password file entry
    getpwuid (3) - get password file entry
    grpconv (8) - convert to and from shadow passwords and groups.
    grpunconv (8) - convert to and from shadow passwords and groups.
    mmsitepass (8) - Set the Mailman site password, prompting from the terminl.
    passwd (1) - change user password
    passwd (1ssl) - compute password hashes
    passwd (5) - The password file
    pg_passwd (1) - change a secondary PostgreSQL password file
    putpwent (3) - write a password file entry

    Reading through this info, you realize that:

    passwd (1) - change user password

    has the info you want, so you type:

    man passwd

  • How do I know a problem has been reported?

    Generally it is better to assume that a problem has not been reported. This is especially true with stuff that has been broken for a couple days. If you'd expect that something could be fixed quickly and it hasn't been, then odds are nobody has reported the problem.

  • How can I get human help?

    1. Stop by Olsen 312.

    3. Send email to help AT cs.uml.edu.

    Generally you'll get quicker results by asking the folks in 312 first. If you want help at 3 a.m., or want more than one person to attempt a solution, try sending email to help AT cs.uml.edu.

  • What if there is nobody in Olsen 312?

    If it's between 9am and 5pm it is likely that staff is in a lab or office working on a problem. Try sending email to help AT cs.uml.edu with your location for the next hour or so, or check back in 30 minutes. If it is after 5 PM or on the weekend, e-mail help AT cs.uml.edu .

  • When will I get a reply to email sent to help AT cs.uml.edu?

    You will get an automated answer saying the request was delivered, an email when it is solved and possibly another email explaining things further if needed.
