Gnu World Order

The **ddate** command from the **util-linux** package, and all about Discordianism and the Church of the Subgenius! shasum -a256=0d5784cd01e654466a9685f64b1922837cbf26c3905b389b40385048a641e20e

Listener feedback, plus **colrm** and **column** from **util-linux**. Tip: To get information about strange characters in GNU Emacs, place your cursor on the character and then type **Alt**-**x** **describe-char** $ cat example.txt hello world $ cat example.txt | colrm 1 1 ello world $ cat example.txt | colrm 1 6 world $ column --table /etc/fstab shasum -a256=980291fff761cdd1a14df8780f39855f51dca2029aee9bf4a4723a4b04b28b3a

Why use the Linux desktop if the Desktop is dead anyway? Also, more **util-linux**: cal, chrt, col, and colcrt from /usr/bin. shasum -a256=bc048f20cce3c06f4918b26ec9b64f98e96209224ac46dd90bed0b9bb76618c4

Listener feedback about zram and ziptool, and then a discussion about the term "open" shasum -a256=f64df303cfcf15d768de8b076eee46b7df743224bd3894d0f1763c3ab836bd72

Finishing up the binaries in /sbin from the **util-linux** package. Includes **sfdisk**, **swaplabel**, **swapon**, **swapoff**, **switch_root**, **wipefs**, **ziptool**, and **zramctl**. For **zramctl** to work, remember to load the zram module. $ sudo modprobe zram shasum -a256=ce96f42c5279c0c330fdb3bee27b02b45648f331cc7bd7abd917708f2ad6be44

Listener feedbacks from Mastodon, including commentary about the Julian calendar, Flatpak sandboxing problems, Flatpak usability problems, clarification on Bzip2 and LZMA and ZIP compression. 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

Is it really possible to use CentOS or RHEL as a desktop Linux distro? Klaatu finds out! shasum -a256=67e6ed6235fc5ee347f7bec03dbfc09fdd0c429a97d93ec1bb3784c40c9c9d24

Listener feedback from Carl about gauging community health of a project before getting involved with it. Klaatu has defined five community profiles, but has no definitive answers. Listen in and send in commentary if you have ideas on this topic. shasum -a256=cd931753fe11d655a060375a77b32e58e76a5df931c4e4dd9a5c1ee947afd708

Listener feedback. GNU World Order is voted best Linux Podcast of 2018 by [linuxquestions.org](http://linuxquestions.org) but fame is fleeting, and it is no longer 2018. Bzip2 compression. You should run bzip2 compression tests and send Klaatu your results. Controversy over scripts that download and install automatically. A bakery that runs on Emacs and PostgreSQL. Further Grav commentary. Pico CMS. And more! shasum -a256=79e5fff598aa5f676f440cdc22901d5818e709b86bbb96b7d719df5fe54f093f

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

Heaps of listener feedback about licensing, the difference between a user and a developer, the `atool` archive tool, old GNU World Order shownotes, the first couple of applications from **util-linux**: `dmesg`, `findmnt`, `hostname`, `more`. shasum -a256=315500688ce992b7a989cf1cf09d501e97bd724a5b3b4a8e35891e4bac7ebcd7

Coffee across the globe. From the **a** package set of default Slackware packages: udisks, udisks2 (udiskctl), unarj, upower, usb_modeswitch, usbutils, and the utemptor interface to utmp, btmp, and wtmp. Udisks is a friendly interface for interacting with drives. $ udisks --enumerate /org/freedesktop/UDisks/devices/sdc1 /org/freedesktop/UDisks/devices/sdc2 /org/freedesktop/UDisks/devices/sdc /org/freedesktop/UDisks/devices/sde [...] /org/freedesktop/UDisks/devices/sdf1 $ udisks --mount /dev/sdf1 Mounted /org/freedesktop/UDisks/devices/sdf1 at /media/white8gb $ udisks --unmount /dev/sdf1 shasum -a256=6422e3e3addabc6330642565c07235743baaa31c92c9fa479183eb729c47e07a

Episode audio levels adjusted, Flatpak tips, and three great coffees in downtown Raleigh North Carolina. Finishing up the applications-that-start- with-"t" from the **a** set of Slackware: `time` (not the built-in Bash one) and **tree**. shasum -a256=e62186be2b657cce7e294441a32251a1124b723db334d394304f20986413d27c

Webhosting.coop vouchers, THE CLOUD is just a virtual computer on somebody else's (or your own?) cluster of computers, building dependencies on things you already own.

Deep thoughts about licensing, effective licensing, and why groups of free software developers haven't the luxury of turning a blind eye. shasum -a256=e9218e3a0acb122283d16d0ae734fc4b61bcad466ae690a079315a25c75677f3

Tech talk, licensing, ZFS, and more. shasum -a256=75da6d76c6be80b7f8a6d8cf7ff27ad4e77b09c6300d6f1e11948073976d2c21

Klaatu talks about software licensing as related to ZFS, and then covers the **S** section of the **a** package set in Slackware (he also realises mid-way through that he had already covered the **q** and **r** sections and part of the **s** section, but nobody complained about it, so presumably they were all worth a second look). shasum -a256=48725fb3fd7866fd15a7d78569242e4c8810db2c7b3efeac84140bd484571a77
