PowerShell pass arguments with quotes -

-

have useful script named sudo.ps1:

$w=""; foreach($a in $args[1..($args.length-1)] ){ $w += " " + $a }; $w start-process $args[0] -argumentlist $w -verb runas -wait

but can't handle complex command

./sudo.ps1 schtasks /create /f /tn "$vpn_name connection update" /tr "powershell.exe -noexit -command d:\vpn-route.ps1" /sc onevent /ec application /mo "*[system[(level=4 or level=0) , (eventid=20225)]] , *[eventdata[data='$vpn_name']]" /rl highest

problem in obfuscated quotes. in sudo.ps1 quotes opened: 

 /create /f /tn vpn-kosmos6 connection update /tr powershell.exe -noexit -command d:\vpn-route.ps1 /sc onevent /ec application /mo *[system[(level=4 or level=0) , (eventid=20225)]] , *[eventdata[data='vpn-kosmos6']] /rl highest

command executed no error, no work. how can fixed?

if arg contains space, add quotes via """ (thanks petseral). sudo.ps1 works fine:

$w=""; foreach($a in $args[1..($args.length-1)] ){ $w+=" "; if($a -match " "){$w+="""$a"""}else{$w+=$a} }; $w start-process $args[0] -argumentlist $w -verb runas -wait

consider solutions suggested keith hill , bill_stewart, if looking better , more complex decision.

this question has answer here: java inner class , static nested class 23 answers i came across in java, know static nested class why create instance of 'static'. isn't whole idea of 'static' use without instance? understand concept of inner classes, why (and frankly how possible to) create 'instance' of 'static' member @ ? why this: 1- outerclass.staticnestedclass nestedobject = new outerclass.staticnestedclass(); 2- nestedobject.anestedclassmethod(); and not this: 1- outerclass outerinstance=new outerclass(); 2- outerinstance.staticnestedclass.anestedclassmethod(); use on inner classes, keyword static indicates can access inner class without instance of outer class. for example: public class outer { public static class inner { /* code here. */ } } with construction, can create instance of inn

JavaScript - Replace variable from string in all occurrences -

ok, know if have character '-' , want remove in places in string javascript, ... someword = someword.replace(/-/g, ''); but, when applying array of characters, s not working ... const badchars = ('\/:*?"<>|').split(''); let filename = title.replace(/ /g, '-').tolocalelowercase(); (let item = 0; item < badchars.length; item++) { // below not work global '/ /g' filename = filename.replace(/badchars[item]/g, ''); } any ideas? /badchars[item]/g looks badchars , literally, followed i , t , e , or m . if you're trying use character badchars[item] , you'll need use regexp constructor, , you'll need escape regex-specific characters. escaping regular expression has been well-covered . using that: filename = filename.replace(new regexp(regexp.quote(badchars[item]), 'g'), ''); but , don't want that. want character class: let filename = title.replac
