This section lists the scripts included with Amanda, see the individual man page for instructions on using them.

Script properties work just like application properties: they are insensitive to case, and - (dash) and _ (underscore) may be used interchangeably. SCRIPTS OUTPUT PROPERTY
A pre-dle-amcheck, pre-dle-estimate or pre-dle-backup executed on the client can output property on stdout that are sent to the application. If the output line matches "PROPERTY str1 str2", Amanda sets a property called "str1" by the value of "str2", that property is sent to the application. SEE ALSO
