Powershell script calls other powershell script with read-host lines -

i have multiple powershell scripts, each of them has read-host lines, user can provide values script, example name of server or true/false in cases.

ike create powershell script, call other scripts, question: there way main script fill in read-host values?

or best way handle then? prefer not change current existing scripts already.

stop trying re-invent wheel. powershell has ability prompt missing parameters, use read things server names. has ability prompt confirmation before doing dangerous:

ps c:\> function foo-bar >> { >>     [cmdletbinding(supportsshouldprocess=$true, >>                   confirmimpact='high')] >>     param >>     ( >>         # target server >>         [parameter(mandatory=$true, >>                    valuefrompipeline=$true, >>                    valuefrompipelinebypropertyname=$true, >>                    valuefromremainingarguments=$false, >>                    position=0)] >>         [validatenotnull()] >>         [string[]] >>         $servername >>     ) >> >>     process >>     { >>         foreach ($srv in $servername) { >>             if ($pscmdlet.shouldprocess("$srv", "foo-bar server")) >>             { >>                 write-output "$srv has been foo'ed" >>             } >>         } >>     } >> } >> ps c:\> foo-bar  cmdlet foo-bar @ command pipeline position 1 supply values following parameters: servername[0]: first servername[1]: second servername[2]: third servername[3]:  confirm sure want perform action? performing operation "foo-bar server" on target "first". [y] yes  [a] yes  [n] no  [l] no  [s] suspend  [?] (default "y"): y first has been foo'ed  confirm sure want perform action? performing operation "foo-bar server" on target "second". [y] yes  [a] yes  [n] no  [l] no  [s] suspend  [?] (default "y"): second has been foo'ed third has been foo'ed ps c:\> foo-bar alpha,beta -confirm:$false alpha has been foo'ed beta has been foo'ed ps c:\> 

put code cmdlets , use shouldprocess , have full control on when user prompted continue , whether or not prompted missing values.

this gives dry-run support free:

ps c:\> foo-bar alpha,beta -whatif if: performing operation "foo-bar server" on target "alpha". if: performing operation "foo-bar server" on target "beta".
