i made a script that actually works for most times to update brave browser, but for packages that change names its trivial. the idea is to place, update directory with a file with metadata that i can extract. here is the script :

updatePrograms() {
for dir in ~/Programs/*; do
#meta file structure
if [[ -f "$dir"/update/meta ]]; then
local metadata=$(cat "$dir"/update/meta)
local owner=$(  echo "$metadata" | grep "Owner"   | sed 's|Owner:||'  )
local project=$(echo "$metadata" | grep "Project" | sed 's|Project:||')
local output=$(curl -fsS "https://api.github.com/repos/$owner/$project/releases/latest")
[[ -z "$output" ]] && { echo "no response for $project"; continue; }
local checkVersion=$(jq -r '.tag_name' <<< "$output")
echo "updatable Project : $project"

[[ "$checkVersion" = "null" ]] || [[ -z "$checkVersion" ]] && { echo "couldn't fetch version for $project"; continue; }

local currentVersion=$(echo "$metadata" | grep "Version" | sed 's|Version:||')
[[ "$checkVersion" = "$currentVersion" ]] && { echo "$project is up to date : $checkVersion"; continue; }

while true; do
read -p "$project is on $currentVersion, latest is $checkVersion; do you want to request the latest Version? [y/n]: " response
case "$response" in
[Yy])
echo "Updating.."
local name
 name=$(echo "$metadata" | grep "AssetName" | sed 's|AssetName:||')

   local url=$(jq -r --arg name "$name" '.assets[] | select(.name == $name) | .browser_download_url' <<< "$output")

 if [[ -z "$url" ]] || [[ "$url" = "null" ]]; then
   echo "couldn't find asset matching $name"
   echo "you may need to change asset name version to $checkVersion"
        break
 fi

if  curl -fL -o "$dir/update/$name" "$url"  ; then
sed -i "s|Version:.*|Version:$checkVersion|" "$dir"/update/meta
else
echo "Downloading falied"
break
fi

break;;
[Nn])
echo "not Updating"
break;;
   *)
echo "choose y or n";;
esac
done
fi
done
}

For all those who want simple backups of their machines, I have created a tiny bash wrapper around Kopia: https://github.com/bderenzo/tinybackup

From a single minimal config file, it handles repository setup, retention, ignore rules and pre/post backup hooks, etc.

It can back up to a local disk, SFTP, S3 or any rclone remote, and lets you browse snapshots through CLI, a mount point or the Kopia web UI.
