Vista - Script Parameters

Is there a method to create script command line parameters similar to cmdlet
parameters that are not positional? I would like to create a script
containing options/parameters that require arguments.

Example:
scriptname -Filter *.ps1 -path ./
parses the same as
scriptname -path ./ -Filter *.ps1

To specify parameters in a script use the param statement at the beginning
of the script. Script parameters could be pass in any order as long as the
parameter name --or its first chars-- is placed before its value. They are
consider positional when no parameter name is defined, any extra values are
picked up by $args.

@'
# beginning of scriptX
param($filter, $path)
"`$filter is $filter"
"`$path is $path"
if ($args) {"`$args is $args"}
# end of scriptX
'@ > scriptX.ps1


# either way works properly:
../scriptX -Filter *.ps1 -path ./
../scriptX -path ./ -Filter *.ps1

# positional assignment
../scriptX *.ps1 ./

# positional incorrect assignment
../scriptX ./ *.ps1

# extra values picked up by $args
../scriptX -path ./ -Filter *.ps1 1 abc 009 yyz

Thank You Kiron,

My mistake was having filter and path as [switch] types in my param
declaration. Doh

Dear Kiron,

When I tried to run the script, I got this error message: "The term
'param' is not recognized as a codlet, function, operable program, or script
file.".
Kindly help.

Thanks.

The 'param' keyword is used to declare parameters for script files,
functions and filters. Parameters are declared inside parenthesis. The
'param' keyword is not used when the parameters are declared before the
script block of a function or filter.

Place the following in a file named scriptX.ps1

# beginning of scriptX
param($filter, $path)
"`$filter is $filter"
"`$path is $path"
if ($args) {"`$args is $args"}
# end of scriptX

Then you can test it.
