Powershell remove trailing spaces in powershell output

Question

I am trying to format the output of my command for usage on another machine. I use the trim() function but still PowerShell insists on making the strings equal length.

I think it has to do with me setting the size of the string but I had to do this to avoid the paths being truncated. How can I circumvent this behavior?

This is my command:

Get-ChildItem -Recurse .\x\ -File | Get-FileHash -Algorithm MD5 | Select-Object @{Name = 'Hash'; Expression = {$_.Hash.ToLower()}}, @{Name = 'Path'; Expression = { Resolve-Path -Path $_.Path -Relative }} | Format-Table -HideTableHeaders -AutoSize | Out-String -Width 10000 | ForEach-Object {  $_.Trim().replace('\', '/').trimend()} > output.md5

this is the output:

11ddbaf3386aea1f2974eee984542152 ./x/ffff.txt

Santiago's answer is the preferable solution, but note that the only reason your (inefficient) approach didn't work is that you forgot to add -Stream to your Out-String call so as to request line-by-line output. — mklement0

Thank you for the feedback! I am new to working with PowerShell so I learned a lot working on this issue. — Moopsish

Don't use Format-Table and Out-String -Width instead use a loop to construct an array of strings:

Get-ChildItem -Recurse .\x\ -File | Get-FileHash -Algorithm MD5 | ForEach-Object {
    '{0} {1}' -f $_.Hash.ToLower(), (Resolve-Path $_.Path -Relative).Replace('\', '/')
} | Set-Content output.md5
