Combine file IO for -replace and Set-Content in PowerShell -

-

i have following script:

$allfiles = get-childitem "./" -recurse | { ($_.extension -eq ".ts")} foreach($file in $allfiles) {     # find , replace dash cased contents of files     (get-content $file.pspath) |          foreach-object {$_ -replace "my-project-name", '$appnamedashcased$'} |         set-content $file.pspath          # find , replace dash cased contents of files     (get-content $file.pspath) |          foreach-object {$_ -replace "myprojectname", '$appnamecamelcased$'} |         set-content $file.pspath          # find , replace dash cased contents of files     (get-content $file.pspath) |          foreach-object {$_ -replace "myprojectname", '$appnamepascalcased$'} |         set-content $file.pspath     }

it takes file , replacing, saves file. takes same file , more replacing saves file again. 1 more time.

this works, seems inefficient.

is there way replacing , save file once?

(if possible, prefer keep readable style of powershell.)

sure, chain replaces inside foreach-object block:

$allfiles = get-childitem "./" -recurse | { ($_.extension -eq ".ts")} foreach($file in $allfiles) {     (get-content $file.pspath) |          foreach-object {             # find , replace dash cased contents of files             $_ -replace "my-project-name", '$appnamedashcased$' `                -replace "myprojectname", '$appnamecamelcased$' `                -replace "myprojectname", '$appnamepascalcased$'         } |         set-content $file.pspath     }
