Updates the APT package cache for PackageInfo.
|
|
|
|
-d, --dir <DIR> Specify directory for APT package cache.
|
|
-v, --verbose Be more verbose than normal.
|
|
-V, --very-verbose Be even more verbose than normal.
|
|
-h, --help Display this message and exit.
|
|
|
|
Note:
|
|
Please separate each option with a space, eg:
|
|
$0 -v -d /home/bot/aptdir
|
|
Rather than:
|
|
$0 -vd /home/bot/aptdir
|
|
|
|
This script is intended to be run automatically (eg: cron), so it shows no output by default.
|
|
You can make the script more verbose with the -v/--verbose or -V/--very-verbose options.
|
|
The -d/--dir option sets the directory where this script looks for *.list files for apt-get.
