# Purpose {{{
## Create a temp file (to monitor) if an upgrade is available for Zoom client
## from official website https://zoom.us/download
## It's based on .deb package installation to check the current version.
## It can also compare the current available version in APT repositories
## if "repo" is given as first argument.
## How-to use {{{
### 1. Create a cron job, eg:
#00 20 * * * root /opt/repos/ipr.scripts/app/check.zoom.update
### 2-1 Create a cron job to compare the version available in an APT repository:
#00 20 * * * root /opt/repos/ipr.scripts/app/check.zoom.update repo
### 2. Monitor the temp file: /tmp/.zoom.upgrade
# Or enable MAILTO in cronjob and edit the script to print a message.
# Or send a mail.
# …
## }}}
## Inspired by https://github.com/pazepaze/zoom-autoupdater/blob/master/autoupdate-zoom.sh
# }}}
# Expect maximum 1 argument {{{
if [ $# -gt 1 ]
then
cat << HELP
check.zoom.update --
Compare current version of an installed Zoom client and the last available.
EXAMPLE:
- Compare the current version installed from .deb file
check.zoom.update
- Compare the current version from apt's repository
check.zoom.update repo
