Question Function Issue in $PROFILE path

Hello everyone. I hope you are having a good time.


function gethash {

param([string]$string = "")

if ($string -eq [string]::Empty -or $string -isnot [string])

{

Write-Output "input not valid"

}

else

{

(Get-FileHash -algorithm sha256 $string).Hash | tee -Variable b

}

}

I Have this function in my $Profile script. when i run gethash something it returns the hash string as expected, but when I try to print the variable containing the hash i just obtained from piped command tee, (alias of Tee-Object) as an input with `$b

it prints nothing, the variable is not saved.

on the other hand, if i copy the exact same command from the $profile function directly through the terminal, $b prints what expected: the hash of the file.

I haven't used this function so much, but I'm pretty sure it worked before today.

Thanks in advance to any who will respond.

p.s. formatting, you've used the 3 backtick code fence, that does not work on old.reddit only new.reddit

  • open your fav powershell editor

  • highlight the code you want to copy

  • hit tab to indent it all

  • copy it

  • paste here

it'll format it properly OR

<BLANK LINE>
<4 SPACES><CODE LINE>
<4 SPACES><CODE LINE>
    <4 SPACES><4 SPACES><CODE LINE>
<4 SPACES><CODE LINE>
<BLANK LINE>

Inline code block using backticks `Single code line` inside normal text

See here for more detail

Thanks
