ruario

To print the time in Swatch .beats from the terminal, issue the following:

printf @;TZ=UTC-1 date '+scale=2;((%H*60+%M)*60+%S)/86.4'|bc

You can save this as a shell alias so that you can check the time in .beats whenever you like alias beat="printf @;TZ=UTC-1 date '+scale=2;((%H*60+%M)*60+%S)/86.4'|bc".

Notes:

ruario

This is a short shell script to make date named directories.

#!/bin/sh
a=`TZ=UTC-1 date +%y%m%d-%T`;b=${a#*-};c=${b#*:}
mkdir -v ${a%-*}`printf %04d $(echo "((${b%%:*}*60+${c%:*})*60+${c#*:})/8.64"|bc)`|grep -Eo \[0-9]+

Usage

ruario

The following is a quick guide on how to manually download, extract and run Signal for Linux on a non-(deb)apt based distro (and includes a shell script that automates the entire process). This is for use when no suitable, native (re)package is available. It also includes some additional instructions on how to integrate with your desktop environment. Almost any recent distro (configured for desktop use) will likely have all the dependencies already installed—especially so if you already have any other Electron apps or a Chromium based browser installed, since they will require the same things.

[Note: Triple-click to easily select any of the lines below for copy and pasting into the terminal]

Fetch, extract and launch

• Switch to a directory you think is suitable for housing Signal (for example ~/opt)

mkdir -p ~/opt && cd ~/opt

ruario

#!/bin/sh -eu
# Check for -s as an argument and if so convert decimal time to 'standard time'
if [ "${1-}" = '-s' ]; then
  if [ -n "${2-}" ]; then
    TIME_IN_SECS="$(echo 864*$(echo "$2" | tr -d :)/10 | bc)"
    if [ "$(uname -s)" = Darwin ]; then
      date -j -f "%s" "$(expr $(date -j -f '%H:%M:%S' '00:00:00' '+%s') + $TIME_IN_SECS)" '+%H:%M'
      exit 0
    else
      date --date="0 today + $TIME_IN_SECS seconds" '+%H:%M'

# This script will convert an official Vivaldi Linux package into Slackware
# package format.
#
# To use, just run this script, followed by the name of the Vivaldi package.
#
# Note: Since this script was created with Slackware 15 and above in mind, it
# uses the new 'douninst.sh' script to clear down any proprietary media libs
# fetched by 'update-ffmpeg' during post install.
