What happens when I press “Shut Down” from the GUI? @don_crissti That much I now understand. What I'm interested in is precisely this "signal". What is the client that sends it? |

How to write a script to read wifi SSID and password from USB drive at boot up and auto logon to wifi network @szielenski Third suggestion, if you're conversant with udev,save the Perl script on your thumb drive and write a udev rule that would mount your drive at a specified point and run the script off it as soon as it's connected. |

How to write a script to read wifi SSID and password from USB drive at boot up and auto logon to wifi network @szielenski Another fun thing you might want to try: don't hardcode a mount point in the script at all. Only hardcode the thumb drive's UUID (which you can find through udevadm) crawl /sys (I'm guessing) to check whether a device with this UUID is connected to a USB port (so your script can bail sanely if it isn't) and if so, crawl /dev to determine whether it's mounted so you can mount it yourself if necessary. |

How to write a script to read wifi SSID and password from USB drive at boot up and auto logon to wifi network +1 You might want to couple this with an entry in /etc/fstab to ensure your thumb drive is always mounted at the same mount point. I wouldn't rely on automounting for this because you may have some other USB stick plugged in that grabs the mount point you're relying upon. |

How to repair system if kernel panic? @xliiv I'm sorry to report that I couldn't solve my libc issue and had to reinstall as @schaiba suggests. |

perl script explanation please$word would be a word read from the file (this example seems to assume an input file with one word per line) and $occurrences would contain the number of times this word has occurred in the file because it's incremented every time the $word is encountered. |

perl script explanation please Well $line++ by itself would do no good. It would actually produce a nonsensical value by "incrementing" the last character in the variable. Remember that $line actually contains the contents of the file's line not the line number. What is done here, is that the %count hash entry keyed by the contents of the $line variable is incremented (because the number of occurrences has increased by one) and created with a value of '1' if it didn't exist before. |

How to add a line from a list into another file when a specified line is found? +1 Neat trick! I know this is rich coming from the guy who proposed a perl answer, but it feels a bit "write-only" :) |

How to repair system if kernel panic? @MichaelKjörling This doesn't necessarily point to faulty hardware. I faced a similar issue recently (though with Squeeze) after a forced reinstall of libc. chroot failed to execute bash. |
