Trying to modify to different files and getting two different outcomes. The successful file "autoexec.cfg works fine. Here is the file contents and powershell code.
c:\temp\autoexec.cfg contains:
disable_write_track = true
webgui_port = 8470
powershell code to modify file:
$WGP = get-random -minimum 8000 -maximum 8999
$line = Get-Content "C:\temp\autoexec.cfg" | Select-String webgui_port | Select-Object -ExpandProperty Line
$content = Get-Content "C:\temp\autoexec.cfg"
$content | ForEach-Object {$_ -replace $line,"webgui_port = $WGP"} | Set-Content "C:\temp\autoexec.cfg"
The file that fails sets up like this.
c:\temp\serverSettings.lua contains:
cfg =
{
["port"] = 10302,
} -- end of cfg
powershell code to modify file
$DCSP = get-random -minimum 10000 -maximum 19999
$line = Get-Content "C:\temp\serverSettings.lua" | Select-String port | Select-Object -ExpandProperty Line
$content = Get-Content "C:\temp\serverSettings.lua"
$content | ForEach-Object {$_ -replace $line," [\`"port\`"] = $DCSP,"} | Set-Content "C:\temp\serverSettings.lua"
The file does not change except it does. I have the file open in Notepadd++ and after running the code Notepad++ sees the file has been changed and wants to reload but there are no changes.
>Solution :
-replace is a regex operator, and [] is a special construct in a regular expression and needs to be escaped properly.
The easiest way to do that is with [regex]::Escape():
$content | ForEach-Object {$_ -replace [regex]::Escape($line)," [\`"port\`"] = $DCSP,"} | Set-Content "C:\temp\serverSettings.lua"
