Item discovery:
Description::
 Discovery of files or directories. 
::
Parameters::
 directory 	''		''			# directory to scan
 mask 		%		''			# mask to search. Use % instead of * in mask. Like '%' to find all objects, '%.txt' to find all .txt files.
 type 		d		'^(d|f|l)$'		# Type of objects to find (f=file,d=dir,l=link)
 maxdepth 	1		''			# depth to search. 1 means only one directory, not subdirs.
 sort 		du/-	 	'^(du|name)/([+-])$'	# how to sort results (name/[+-], du/[+-]).
 maxobjects 	50		''			# maximum objects to find. 0 means no limit.
 who 		zabbix 		'^(root|zabbix)$'	# which permissions to use. Sudo must be installed for root. Default is zabbix
::
Type: string
Testparameters: /tmp/ /tmp/,%,f,1,name/+,10,root
