在 Powershell 中运行可执行文件，特定文件名为 arguments

Question

I'm trying to batch-convert heic images to png images using Powershell. What I have tried:

Get-ChildItem -Include ('*.HEIC', '*.heic') -File | & .\bin\vips.exe copy $_.Name "$(_.BaseName).png"
Pause

and

Get-ChildItem -Include ('*.HEIC', '*.heic') -File | & .\bin\vips.exe copy $_.Name ($_.BaseName + '.png')
Pause

Both times I'm getting an error VipsForeignLoad: file ".png" does not exist which tells me it treats ".png" as the first (and only) argument and ignores the object Name and Basename properties.

Answer 1

You're missing a $. "$($_.BaseName).png" I would use -Filter vs -Include as it is more efficient.

Edited: Try this approach bypassing the Pipe and see if you get a different result. I've also added some additional code to insure everything is fully evaluated. If this approach works you can experiment with reducing come of the $() evaluation levels.

Also are you using Linux? Some of my googling led me to believe you might be. If so you should specify this in your tags for clarity.

Clear-Host
$x = Get-ChildItem -Filter "*.HEIC" -File
ForEach ($File in $x) {
  & .\bin\vips.exe copy "$($File.FullName)" $("$($File.BaseName)" + ".pdf")
}

Also note the file extension in the Filter is case insensitive so no need to repeat.

I'd also recommend adding the -Path parameter for clarity rather than assuming the default directory but that's just me.
