PowerShell: concatenate strings with variables after cmdlet -

-

i new powershell. have looked online answer, no avail. perhaps i'm phrasing question incorrectly.

i find myself in situation have concatenate string variable after cmdlet. example,

new-item $archive_path + "logfile.txt" -type file

if try run this, powershell throws following error:

new-item : positional parameter cannot found accepts argument '+'.

am not concatenating string correctly? i'd not have declare variable before each cmdlet in (e.g., $logfile = $archive_path + "logfile.txt", new-item $logfile -type file). also, won't concatenating file path.

you error because powershell parser sees $archive_path, +, , "logfile.txt" 3 separate parameter arguments, instead of 1 string.

enclose string concatenation in parantheses () change order of evaluation:

new-item ($archive_path + "logfile.txt") -type file

or enclose variable in subexpression:

new-item "$($archive_path)logfile.txt" -type file

you can read argument mode parsing get-help about_parsing

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
