Usage: $0 [-q] [-o] [-z zm.conf] [-w WEB DIRECTORY] [-l LOG DIRECTORY] [-t TMP DIRECTORY] [CONTENT DIRECTORY]
|
|
|
|
OPTIONS:
|
|
-h Show this message and quit
|
|
-z ZoneMinder configuration file
|
|
-w Override the web directory from zm.conf
|
|
-q Quick mode. Do not change ownership recursively.
|
|
-l Override the zm log folder location
|
|
-t Override the zm temp folder location
|
|
-o Enable old legacy symlinks inside ZoneMinder's webroot folder
|
|
|
|
If the -w option is not used to specify the path to the web directory,
|
|
the script will use the path from zoneminder's configuration file.
|
|
If the -z option is used, the argument will be used instead of zm.conf
|
|
Otherwise, it will attempt to read zm.conf from the local directory.
|
|
If that fails, it will try from /etc/zm.conf
|
|
|
|
Newer versions of ZoneMinder no longer require symlinks to the events and
|
|
images folders inside the zm webroot. Indeed this is a security risk, and
|
|
$0 will no longer create these unless the -o option is specified.
