Powershell Format-Hex how to truncate decoded text column on right - powershell

Question

Hi I'm trying to use power shell command Format-Hex and it works well .
In normal hex editor there is option to hide and not include the decoded text characters on the right .
I couldnt figure out how to use Format-Hex in power shell to only show :
00000030 1A 00 00 00 00 00 00 00 68 74 74 70 3A 2F 2F 66
Is there a parameter to do that with PS C:\Users\YourName\Desktop>Format-Hex file.dll instead of the below ? I am just confirming if any such parameter or cli tool that exists to allow when using Format-Hex command not looking for truncation or file parsing solutions .

I read the help on Format-Hex

Answer 1

Format-Hex has no parameter that would omit the last column from its output.
If you're running on macOS or Linux, you can use the standard utilities available there, such as hexdump.
However, at the expense of performance, you can write a simple wrapper function around Format-Hex:
function Format-HexBare {
Format-Hex #args |
Out-String -Stream |
ForEach-Object `
-Begin { $maxLen = if ($IsCoreCLR) { 64 } else { 58 } } `
-Process {
$line = $_
try { $line.Substring(0, $maxLen) } catch { $line }
}
}
Note: The - PowerShell edition-specific - max. line length excluding the last column is hard-coded above, for the following reasons:
A robust regex solution would be challenging.
The .Substring() solution also eliminates the header of the unwanted column (which is only displayed in PowerShell (Core) 7+).
While there is no guarantee that output formats won't change over time,[1] it is unlikely to in this case. Should it happen nonetheless, the function is easy to adapt.
[1] The specifics of the for-display formatting - meant for the human observer only - aren't part of PowerShell's public contract with respect to backward compatibility.
