Powershell remove blank lines in the format-list, puts the result in the clipboard and outputs the txt

I just learned about Powershell, I've been searching for more than 24 hours and reading a lot of articles, but I still haven't found a way to solve the following problems (because I'm not smart), hope someone can help.

1. How to remove blank line in output of format-list?

I wrote the following code to check the hash of a file:

powershell -noexit Write-Host '%1';get-filehash -literalpath '%1' -algorithm MD5 | format-list -property algorithm, hash; get-filehash -literalpath '%1' -algorithm SHA1 | format-list -property algorithm, hash

The following results

D:\Downloads\new 1.txt


Algorithm : MD5
Hash      : B1D91A5CB33FDCD3CF24964769E23BDA





Algorithm : SHA1
Hash      : 748B44A79C7FA38898C0248DE6D1B102A71B36D3

There are 5 blank lines in between the two results, how can I shorten it to just 1 line?

I also tried using select-object like this, the result was nice, but for hash functions like SHA512, it didn't show the full range but instead had "..." marks at the end.

powershell -noexit Write-Host '%1';get-filehash -literalpath '%1' -algorithm MD5 | select-object -property algorithm, hash;get-filehash -literalpath '%1' -algorithm SHA1 | select-object -property algorithm, hash;get-filehash -literalpath '%1' -algorithm SHA256| select-object -property algorithm, hash

Please note:

  1. I need the code on one line to add to the registry.
  2. I saw an answer here, but it was too complicated for me. I don't know what to do to incorporate it into my code: Remove empty lines after simple Format-list command

2. How to concurrently: display results in Powershell, copy to clipboard and output txt file?

If I use "| clip" after format-list, it doesn't work.

powershell -noexit Write-Host '%1';get-filehash -literalpath '%1' -algorithm MD5 | format-list -property algorithm, hash;get-filehash -literalpath '%1' -algorithm SHA1 | format-list -property algorithm, hash | clip

3. Output file

I can't output file to C drive (or does anyone know any other way?), so how can Powershell output file to another available drive? For example, your D drive is locked, Powershell will recognize that and output file to drive E.

Or is there a way to open notepad and automatically paste the results there, then you can choose to save the file or not?

Thank you very much for all the help.

Solution

  • if all you want is a kinda-sorta "one liner" that outputs the algo & hash to a single line, something like this will work [grin] ...

    the code ...

    Get-ChildItem -LiteralPath $env:TEMP -Filter '*.log' -File | Get-FileHash -Algorithm MD5 | ForEach-Object {'Algo = {0}; Hash = {1}' -f $_.Algorithm, $_.Hash}

    what it does ...

    • grabs the files to work with
      i chose the log files from my temp dir.
    • pipes each to Get-FileHash with the desired algo
    • pipes that to ForEach-Object
    • builds a string with the -f string format operator
    • sends that out to the screen
      you can send it elsewhere as needed.

    the output ...

    Algo = MD5; Hash = B8D9CD8AEAC35E8C018A9F612196D2F7
Algo = MD5; Hash = 4FF28D9F2ABAC624DC04EA690B613509
Algo = MD5; Hash = FC738758B9ECA9E36BB15C8AEA592BEC

Algo = MD5; Hash = 23088A1A7FB398B077DF7CB52F9925DD
Algo = MD5; Hash = 8679AAAC06D4EE1E80E28C356E650189

    i am a tad confused that you don't want the file name.
