How to get to the CUPS interface through a terminal web browser, like **w3m**,**lynx**, or **elinks**. The philosophy and culture of bug reporting: 1. A bug is any unexpected interaction between you and a product. 2. A bug report offers you an opportunity to troubleshoot a problem. Ideally, it results in a solution before even being filed. Otherwise, it is a recipe for the developer to experience the same problem as you have. 3. Bug reporting is collaboration. When you file a bug, you are not disturbing the developers, nor are you exposing them as poor or nefarious programmers. You are developing along with them in an attempt to optimize an application you love. 4. A good bug reporting tool is also a task management tool. shasum -a256=eab13cba2585e7f9fe07ad2732c646d19fe5a77bd540e77b3727ed16cefe00c1

The ending of the **a2ps** package, including **psdiff**, **psbook**, **psmandup**, **psresize**, **psselect**, and **texi2dvi4a2ps**.

The overview of util-linux continues with **mkswap**, which designates a partition of a special hard drive or a special file as "swap" space. _NEVER run **mkswap** on a partition or file that contains data you care about._ $ sudo mkswap /dev/sdx1 The **pivot_root** command mounts a new location as your root whilst simultaneously unmounting the old one. You probably won't ever use **pivot_root** manually yourself. Its typical use case is during system startup, when an initrd is used to bootstrap an environment but then needs to be shunted away when the real root partition becomes available. You can test **pivot_root** in a virtual machine, just as a proof of concept, as described in this episode, but if you have ever used **chroot**, then you have The **raw** command talks directly to block devices, useful for fancy databases or other high-performance things that don't need a filesystem because they use their own optimized system for managing data. On some systems (like Slackware), you may need to do **modprobe raw** before using **raw**. NEVER run raw against a block device with data (that you care about) on it. Here is a really simple proof of concept demo exercise: # raw /dev/raw/raw1 /dev/sdx # echo "gnu world order" > /dev/sdx # dd if=/dev/raw/raw1 count=1 gnu world order [...] The **setserial** command sets and reports serial ports on a Linux system. On Slackware, you can see the script that generates serial port definitions in **/etc/rc.d/rc.serial**, with its associated config file being **/etc/serial.conf** On a distro using systemd, there is a unit file that creates serial ports. Serial ports are usually accessible to the group **dialout**, so if you are having trouble talking to a device over a serial port, be sure to add yourself to the **dialout** group, and then log out and log back in. Permissions for devices that communicate over a serial port (like an Arduino) can be managed manually (**chmod 660 /dev/ACM0**, for instance) or you can script **udev** to set permissions upon connection.

The journey through the **util-linux** from the **a** package set of Slackware continues. First, a tutorial on `getopt`, an argument parser for Bash and Tcsh. Here is a demonstrative sample script: #!/usr/bin/bash ## or you can just use /bin/sh OPTS=`getopt --options f --long foo --alternative -- "$@"` eval set -- "$OPTS" echo "Raw input: $OPTS" while true ; do case "$1" in -f|--foo) echo "Option f has been toggled on" ; shift ;; --) shift ; break ;; esac done # this outputs anything # left over after parsing # valid options for i in "$@" ; do echo "$i" done You can add more options, and you can add an allowance for arguments. Here is a slightly more complex version of the script: #!/usr/bin/bash OPTS=`getopt --options f,b: --long foo,bar: --alternative -- "$@"` eval set -- "$OPTS" echo "$OPTS" while true ; do case "$1" in -f|--foo) echo "Option f has been toggled on" ; shift ;; -b|--bar) echo "Option b has been set to $2" ; shift 2 ;; --) shift ; break ;; esac done for i in "$@" ; do echo "$i" done After the coffee break, Klaatu covers `kill`. Because he recorded this episode on the same night as the previous episode, he does make reference to some settings from the previous episode (specifically, a hostname setting). That makes this episode a sequel to the previous one, meaning Klaatu owes you an extra episode sometime. Also, `mountpoint`, `mount`, `unmount`, `wdctl` and `watchdog` [gnu.org/software/libc/manual/html_node/Example-of-Getopt.html](https://www.gnu.org/software/libc/manual/html_node/Example-of-Getopt.html) A great article about the `eval` and `set` on [Linux Journal](https://www.linuxjournal.com/content/bash-preserving-whitespace-using-set-and-eval) [Watchdog daemon](http://www.sat.dundee.ac.uk/psc/watchdog/watchdog-testing.html) [Systemd interface to Watchdog](http://0pointer.de/blog/projects/watchdog.html) shasum -a256=4f760557e34dcaf6e9c4e2f73c6602b1c054debe584cea890953279d334174a6

Season 13 begins! We have switched to a fancy new hosting provider, [Webhosting.coop](http://webhosting.coop), a cooperative web hosting organization run in part by Josh Cox, a long-time supporter of the show. Introductory episodes about [Linux](https://gnuworldorder.info/#0x0) and [Slackware](https://gnuworldorder.info/#0x1) have been posted. If you're new to Linux, start with these episodes!. For previous seasons of this show, visit the archive at http://gnuworldorder.info In _this_ episode, Klaatu reads some listener feedback, and then ponders why we don't just build open source on Windows or Mac. shasum -a256=ff9eebc17d997316ead082b899e1497813d34b13056f8d989df0286c6aa554e2
