# 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.
|
||
# …
|
||
## }}}
