How to use "-join" command after a pipeline

I'm training in powershell 3.0 and i'm trying to get the content of a file in bytes, sending it through a pipeline in order to join the result as by default there's one byte per line, and then send the result in a file.

Here's the command I'm using:

get-content 'My file' -Encoding byte | $_ -join ' ' | Out-File -path 'My result file'

So to summarize, does someone know how to use a -join after a pipeline?

Solution

  • You can't do the -join via the pipeline because the pipeline stage only sees one object at a time.

    Instead, treat the collection returned by get-content as a single object and join that.

    (get-content -path 'my file' -Encoding Byte) -join ' ' | out-file -path 'My result file';
