I will chair a "Linux Quiz" at the next TLUG technical meeting, on May 10th: ---- Title: Linux Quiz Summary: Would you like to explore and expand your knowledge of Linux? The Linux Quiz will be an interactive discussion where people of all experience levels, from beginners to seasoned sysadmins, can ask questions and share their knowledge about all things Linux in a friendly, non-competitive atmosphere. ---- I hope that the quiz will be fun for all, but an addition goal is to introduce more people to TLUG. If you know anybody [in the area] who would be interested in the topic, please encourage them to attend! Michael: Would you like to invite Tokyo PC Users Group members who might be interested? Kalin: Would you like to invite Tokyo Hackerspace members who might be interested? In preparation, I would like to collect possible quiz questions via email. If you would like to contribute one or more questions, please email me (off-list) the question(s) as well as any notes or links to references. If you prefer to be an anonymous source, please let me know. For reference, I am putting a sample question below. Please note that I will organize the contributed questions, but I will not be able to guarantee that any particular question will be covered, as the quiz will be interactive and limited by time. Also note that it is a *Linux* quiz. If there is interest in a more general *Unix* quiz, then perhaps we could do it another time. ;) If you have any general questions, comments, or ideas, let me know! Cheers, Travis ---- Question: What are the permissions of the /tmp directory? Discussion: The /tmp directory has permissions 1777 (displayed in `ls -al` as "drwxrwxrwt"). The final 7 indicates that all users have write permissions in the directory. The leading 1 is referred to as the "sticky bit." It makes it so that files in /tmp can only be unlinked or renamed by root, the directory owner (root in this case), or the file owner. Possible follow-up question: In what other cases might the sticky bit be useful? Submitted by: Travis
