Question

I am trying to rename certain files and then copy them to a backup location as below:

gci $src `
    | ?{!$_.psiscontainer -and $_.extension.length -eq 0 -and $_ -match "tmp_\d{1}$"} `
    | %{ ren -path $_.fullname -new ($_.name + ".ext") } `
    | %{ cpi -path $_.fullname -dest $bkup -force} 

The renaming part is working fine. But the renamed files are not being copied over to the backup location. What I am doing wrong here?

Answer 1

By default renamed items will not be pushed back onto the pipeline, use the -PassThru switch to pass them on:

gci $src `
    | ?{!$_.psiscontainer -and $_.extension.length -eq 0 -and $_ -match "tmp_\d{1}$"} `
    | %{ ren -path $_.fullname -new ($_.name + ".ext") -PassThru } `
    | %{ cpi -path $_.fullname -dest $bkup -force}
