At work we use Zoom extensively for meetings. We also use Ubuntu Linux on our laptops.

Unfortunately, Zoom doesn’t have a very good update mechanism for its client in Linux.

Because of this, I created a script that would check for a new version of the Zoom client and, when there is, download it and notify me.

#!/bin/sh

ZOOM_DEB=zoom_amd64.deb
ZOOM_URL="https://zoom.us/client/latest/$ZOOM_DEB"
cd $HOME/Downloads

# If zoom deb doesn't exist, create a new one with a really
# old timestamp
if [ ! -e $ZOOM_DEB ];then
  touch --date='Jan 1 1900' $ZOOM_DEB
fi

# Find out the last modified date
LAST_MOD=$(date --date="$(curl --location --head $ZOOM_URL 2>&1 | grep
'^Last-Modified:'|sed -E 's/^Last-Modified:\s+(.*)/\1/gm;t;d')")

# if the current file is older than downloadable one, get the new one
if [ $(date --date="$LAST_MOD" +%s) -gt $(date --reference=$ZOOM_DEB
+%s) ];then
    rm -f $ZOOM_DEB
    curl --output $ZOOM_DEB --silent --show-error --location $ZOOM_URL
    # make sure the downloaded file has the right timestamp
    touch --date="$LAST_MOD" $ZOOM_DEB
    # send a notification to the user with a long timeout
    /usr/bin/notify-send --expire-time=172800000  "$ZOOM_DEB updated on
$LAST_MOD"
