\x
Matches the single character x. This provides a way of avoiding the special interpretation of the characters *?[]\ in pattern

And since the parser itself performs backslash substitution, you'll need to escape the backslash to get one through to to the command.

Code: Select all

string match *\\** a*a

string match *\\** a*a

or alternatively, supply braces to eliminate the interpretter from implicitly interpretting special characters itself...

Code: Select all

string match {*\**} a*a
