In resemblance to Regular Expressions, when searching through text strings of names and other textual patterns in mzsh, there are two characters that help you filter text according to a certain criteria:
If you want to use the '*' and '?' wildcards when you are not logged in, the wildcards have to either be enclosed with single or double quotation marks, or preceded with a backslash '\'.
mzsh mzadmin/dr wfgrouplist \* will work.
mzsh mzadmin/dr wfgrouplist "*" will work.
mzsh mzadmin/dr wfgrouplist * -mode D will not work.
The period '.' mark is not a wildcard and is treated as any character.
