The Art of Unix Programming

You can browse my newest book here. If you like it, please order a paper copy. You can get it from Amazon or Barnes & Noble, or direct from Addison-Wesley. The Art of Unix Programming attempts to capture the engineering wisdom and philosophy of the Unix community as it's applied today — not merely as it has been written down in the past, but as a living "special transmission, outside the scriptures" passed from guru to guru. Accordingly, the book doesn't focus so much on "what" as on "why", showing the connection between Unix philosophy and practice through case studies in widely available open-source software. If you're using Opera 5, be aware that it has problems rendering some of the HTML in the browseable version linked above. Revisions for the first print edition are now closed. Instructions for reviewers are here. I have written some notes for translators. Raves: 123456789 Friendly: 12345678910 Pans: 12

TECH SOURCE FROM BOHOL: Linux Keyboard Shortcuts: Safe Way to Exit During System Freezes In Windows, when your system hangs, you can always press Ctrl-Alt-Delete, wait for the Task Manager to open, and kill the process that doesn’t respond. However, Ctrl-Alt-Delete don’t always work the way you want it to leaving you no other option but to do a hard-reset, and perhaps as a result corrupt your data kissing your important files goodbye. In Linux, when your entire system freezes, there are plenty of safe ways to exit and get back on track immediately. Alt + SysRq + (a selection of other keys) will do the magic trick. Note: 'SysRq' key is equivalent to the 'Print Screen' key. Alt + SysR + KKill all processes (including X), which are running on the currently active virtual console. Alt + SysRq + ESend the TERM signal to all running processes except init, asking them to exit. Alt + SysRq + ISend the KILL signal to all running processes except init. Alt + SysRq + LSend the KILL signal to all processes, including init. Alt + SysRq + URemount all mounted filesystems as read-only.
