Edito:
Versión ligeramente modificada que utilizo.
La modificación consiste en omitir los paquetes de tipo "kmod", que no se puede actualizar, evitando así errores cuando aparecen nuevas versiones de esos paquetes. Además, utiliza un script aparte, que comprueba si se ha actualizado la lista de paquetes recientemente, para no volver a actualizarla en tal caso.

Options:
-V, --version Show program name and version and exits
-h, --help Show this help screen and exits
-i, --install [dir] Install opkg-upgrade to [dir] or /usr/sbin
Leave [dir] empty for default (/usr/sbin)
-u, --upgrade-check Returns SUCCESS if there are updates available
Quiet execution, returns 0 or 1
-l, --list-upgrades Prints the list of available updates and exits
-e, --email-list Prints the list of updates in html email format
Includes subject, mime type and html formated data
-s, --ssmtp <email> Use the system's ssmtp to send update reports
You need to install and configure ssmtp beforehand
-a, --always-send Send e-mail even if there are no updates
By default e-mails are only sent when updates are available
-t, --text-only Send e-mail in plain text format.
By default, e-mails are sent in html format.
-n, --no-opkg-update Skip opkg update at the beginning,
may not find packages if not up to date
-f, --force Do not ask for confirmation,
will update everything available
Notes:
- Short options should not be grouped. You must pass each parameter on its own.
- You must have a working ssmtp install to use the ssmtp functionality. Make
sure you can send e-mails from it before trying from opkg-upgrade.
Examples:
$OPKGUP_NAME -n -f # run without updating listings and asking for upgrade
$OPKGUP_NAME --install # install to /usr/sbin/opkg-upgrade
$OPKGUP_NAME -l # just print upgrades available
$OPKGUP_NAME -e # just print html formatted email
$OPKGUP_NAME -s 'mail@example.com' # mail upgrade report if have updates
$OPKGUP_NAME -a -s 'mail@example.com' # mail upgrade report even if NO updates
$OPKGUP_NAME -u && echo 'upgrades are available' || echo 'no upgrades available'

echo "Usage: $OPKGUP_NAME [options]
Options:
-V, --version Show program name and version and exits
-h, --help Show this help screen and exits
-i, --install [dir] Install opkg-upgrade to [dir] or /usr/sbin
Leave [dir] empty for default (/usr/sbin)
-u, --upgrade-check Returns SUCCESS if there are updates available
Quiet execution, returns 0 or 1
-l, --list-upgrades Prints the list of available updates and exits
-e, --email-list Prints the list of updates in html email format
Includes subject, mime type and html formated data
-s, --ssmtp <email> Use the system's ssmtp to send update reports
You need to install and configure ssmtp beforehand
-a, --always-send Send e-mail even if there are no updates
By default e-mails are only sent when updates are available
-t, --text-only Send e-mail in plain text format.
By default, e-mails are sent in html format.
-n, --no-opkg-update Skip opkg update at the beginning,
may not find packages if not up to date
-f, --force Do not ask for confirmation,
will update everything available
Notes:
- Short options should not be grouped. You must pass each parameter on its own.
- You must have a working ssmtp install to use the ssmtp functionality. Make
sure you can send e-mails from it before trying from opkg-upgrade.
Examples:
$OPKGUP_NAME -n -f # run without updating listings and asking for upgrade
$OPKGUP_NAME --install # install to /usr/sbin/opkg-upgrade
$OPKGUP_NAME -l # just print upgrades available
$OPKGUP_NAME -e # just print html formatted email
$OPKGUP_NAME -s 'mail@example.com' # mail upgrade report if have updates
$OPKGUP_NAME -a -s 'mail@example.com' # mail upgrade report even if NO updates
$OPKGUP_NAME -u && echo 'upgrades are available' || echo 'no upgrades available'
