Update rustdesk in Debian/Ubuntu

rustdesk_deb_upd.sh

# Replace _64 to aarch64 or armv7 depends of your arch (use `dpkg --print-architecture` to detect)
P=$(wget -qk -l 0 "https://github.com/rustdesk/rustdesk/releases" -O /tmp/index.html ; cat /tmp/index.html | grep -o 'https:[^"]*.deb' | grep '\/rustdesk-[0-9]*[0-9]\.[0-9].*_64.deb' | sort -r -n | head -1)
wget "$P"
sudo dpkg --install $(basename "$P")

The same in one line

sudo dpkg --install $(basename $(wget $(wget -qk -l 0 "https://github.com/rustdesk/rustdesk/releases" -O /tmp/index.html ; cat /tmp/index.html | grep -o 'https:[^"]*.deb' | grep '\/rustdesk-[0-9]*[0-9]\.[0-9].*_64.deb' | sort -r -n | head -1)))

To paste automatically to the end of .bashrc, you can use this code:

cat<<'EOF' >> $HOME/.bashrc

upd_rustdesk() {
    sudo dpkg --install $(basename $(wget $(wget -qk -l 0 "https://github.com/rustdesk/rustdesk/releases" -O /tmp/index.html ; cat /tmp/index.html | grep -o 'https:[^"]*.deb' | grep '\/rustdesk-[0-9]*[0-9]\.[0-9].*_64.deb' | sort -r -n | head -1)))
}
EOF

Then run source ~/.bashrc
