# SYNOPSIS
|
||
|

**check_updates** [CONFIG_FILE (absolute path)]

# DESCRIPTION
|
||
|
|
|
||
|
|
**check_updates** checks for available updates using *checkupdates* and sends out a mail. It comes with systemd services.
|
||
|
|
|
||
|
|
If no *CONFIG_FILE* is provided, **check_updates** tries to read from *$HOME/.check_updates.conf* and */etc/check_updates.conf* for configuration. It will exit with a non-zero exit code if it cannot find an proper configuration file.
|
||
|
|
|
||
|
|
The following are at least required for the script to work:\
|
||
|
|
- **CHECK_UPDATES_MAIL_ADDRESS=""** which requires *mail.rc* to be configured and '*mailx*' command has be available.
|
||
|
|
|
||
|
|
You can copy this script to */usr/local/bin* and use create a custom **CONFIG_FILE** as user.
