CMD Variable edit replace. Use the syntax below to edit and replace the characters assigned to a string variable.
Syntax %variable:StrToFind=NewStr% %~[param_ext]$variable:Param Key StrToFind : The characters we are looking for NewStr : The chars to replace with (if any) variable : The environment variable param_ext : Any filename Parameter Extension Param : A command line parameter (e.g. 1) This Edit/Replace syntax can be used anywhere that you would use the %variable% such as ECHOing the variable to screen or setting one variable = another param_ext cannot be %* which typically represents a whole set of parameters, but this is easily worked around by setting a variable=%* "StrToFind" can begin with an asterisk, in which case it will replace all characters to the left of "StrToFind". By leaving NewStr blank, you can delete characters. Windows shell string operations (changing backslash to slash)
