I am trying to do the same for https://github.com/eneshecan/whatsapp-for-linux/releases as is described here: Download and install latest deb package from github via terminal but cant get it to work, it seems because the URL is not in the source but only seen in the browser? can anyone help? I just need the full URL as a string so I can download and install the deb file

You could do something like this (kudos to this for the trick that gets the latest version):

base_url="https://github.com/eneshecan/whatsapp-for-linux/releases/download"
version=$(curl --silent https://api.github.com/repos/eneshecan/whatsapp-for-linux/releases | grep -oP '"tag_name":\s*"v\K[^"]+' | sort -h | tail -n1)
wget "$base_url"/v"$version"/whatsapp-for-linux_"${version}"_amd64.deb

  • thanks, different solution :-) I wonder why its so complicated on some github repos I marked it as solution as it works for my use-case :-)

  • @Questi it's because there is no standard here, and every developer can arrange their repository as they want.

I use the following to choose (using bash's select built-in) one or more of the most recent "Glorious Eggroll" Proton releases to download and extract for Steam.

It would be easy enough to modify to download a .deb file from another repo. It does basically the same thing as @terdon's answer, but a bit fancier (the select stuff; and code to avoid downloading a file that has already been downloaded, checking both the current dir and a ./archives/ sub-directory - I like to move older .tar.gz files out of the main working dir to reduce clutter; and code to extract the download if it hasn't already been extracted into the target dir).

#!/bin/bash

GE_API_URL='https://api.github.com/repos/GloriousEggroll/proton-ge-custom/releases'
GE_json='GE-releases.json'
GE_list='GE-releases.list'
compatdir='/var/games/steam/compatibilitytools.d'
archives='./archives'

mkdir -p "$compatdir"

# Don't download the releases file more than once/day
if [ -e "$GE_json" ] ; then
  GE_date="$(stat --printf "%y" "$GE_json" | cut -d' ' -f 1)"
fi
YMD="$(date +%Y-%m-%d)"

if [ "$GE_date" != "$YMD" ] ; then
  wget "$GE_API_URL" -O "$GE_json"
  jq -r .[].assets[].browser_download_url < "$GE_json" |
    grep '\.tar.gz$' | sort -rV > "$GE_list"
fi

#mapfile -t releases < "$GE_list"         # all
mapfile -t releases < <(head "$GE_list")  # latest 10

echo "Currently installed Proton-GE versions:"
ls "$compatdir" | grep GE | sort -rV
echo

export COLUMNS=80
echo "Select a GE release to download and install or 0 to quit:"
select r in "${releases[@]}"; do
  [ -z "$r" ] && break

  tgz="$(basename "$r")"
  [ -e "$archives/$tgz" ] && tgz="$archives/$tgz"
  if [ ! -e "$tgz" ] ; then
     echo "Downloading $r"
     wget "$r"
  fi

  bn="$(basename "$tgz" ".tar.gz")"
  if [ ! -e "$compatdir/$bn" ] ; then
    echo "Extracting $bn into $compatdir/"
    time tar xfz "$tgz" -C "$compatdir/"
  fi

  echo
  echo -n "Select another version to install or 0 to quit: "
done

  • not sure how to use this :P though it would be nice to check if there is already a downloaded file and if its the newest version to not attempt to download and install it :)
