There are two most commonly used ways to check the Slackware version. The first one is the file /etc/slackware-version that shows the system version. $ cat /etc/slackware-version Slackware 15.0 The second method shows more detailed information about the system in this file /etc/os-release. $ cat /etc/os-release NAME=Slackware VERSION="15.0" ID=slackware VERSION_ID=15.0 PRETTY_NAME="Slackware 15.0 x86_64" ANSI_COLOR="0;34" CPE_NAME="cpe:/o:slackware:slackware_linux:15.0" HOME_URL="http://slackware.com/" SUPPORT_URL="http://www.linuxquestions.org/questions/slackware-14/" BUG_REPORT_URL="http://www.linuxquestions.org/questions/slackware-14/" VERSION_CODENAME=stable

For those who haven’t noticed yet, I use the Slackware distribution, and people often ask me “Why do…

DRY is a very important principle that means don’t repeat yourself. As the name suggests, this principle tells us not to repeat code snippets. Many times in a project, we end up copying snippets of code and putting them somewhere else, thus duplicating it. The code can work fine in…

sudo allows ordinary users to temporarily obtain privileges from another user, largely used for super user root privileges. There are advantages and disadvantages to using sudo over su, for example sometimes we just need to perform a task quickly, like updating the system with a single command, like slackpkg update…

During the installation of Slackware we are asked to select a keyboard configuration that makes sense to us, however after installing the system and starting the X server (GUI) the default US layout will still be configured. What we should do to solve this is to copy the configuration file /usr/share/X11/xorg.conf.d/90-keyboard-layout-evdev.conf to /etc/X11/xorg.conf.d/xorg.conf # cp /usr/share/X11/xorg.conf.d/90-keyboard-layout-evdev.conf /etc/X11/xorg.conf.d/xorg.conf
