Unix Recovery Legend

March 16th, 2008 No comments

This classic article from Mario Wolczko first appeared on Usenet in 1986.

Have you ever left your terminal logged in, only to find when you came back to it that a (supposed) friend had typed “rm -rf ~/*” and was hovering over the keyboard with threats along the lines of “lend me a fiver ’til Thursday, or I hit return”? Undoubtedly the person in question would not have had the nerve to inflict such a trauma upon you, and was doing it in jest. So you’ve probably never experienced the worst of such disasters….

So You Want To Be A UNIX Wizard? (The Loginataka)

March 15th, 2008 No comments

I first came across this dialogue several years ago, which I believe was originally written by Eric S. Raymond in 1993.

Speak, O Guru: How can I become a Unix Wizard?

O, Nobly Born: know that the Way to Wizardhood is long, and winding, and
Fraught with Risks. Thou must Attune thyself with the Source, attaining the
arcane Knowledge and Conversation of the System Libraries and Internals. Yea;
and such an all-consuming Time and Energy Sink is this as to greatly Imperil
thy Grade Point Average (if one thou hast), not to mention thy Sex Life (if one
thou hast). But persevere, oh Larval One; rewards beyond the Dreams of Lusers
await thee!

The History of Tux the Linux Penguin

March 10th, 2008 No comments

The wiki at Steve Baker’s site contains a fairly comprehensive history of the Linux mascot.

Linus, “Some people have told me they don’t think a fat penguin really embodies the grace of Linux, which just tells me they have never seen a angry penguin charging at them in excess of 100mph. They’d be a lot more careful about what they say if they had.”

Ever tried to unmount a device in Linux, but can’t because it is apparently still being used by something? If so, then the ‘fuser’ command is what you want. Just type ‘fuser -m’ followed by the path that the device is currently mounted to (e.g. ‘fuser -m /home’), and then you’ll receive a list of all the processes that are currently using it.

The fuser command can also be used to kill the processes as well, just by adding the ‘-k’ option (e.g. ‘fuser -km /home’).
