PowerShell: String Wildcards
Wildcard can be used to represent string patterns.
For example, dir "*jpg" means list any filename ending in jpg.
- Most command's
Pathparameter value is interpreted as wildcard pattern. e.g.dir *.jpglists only files whose name ends in.jpg. - If you don't want wildcard, use the
LiteralPathparameter.
