Correct use of TrimEnd

PowerShell Help
1

I am having a hard time removing a string element with TrimEnd. I am trying to remove the ‘.jrnl’ from the strings

human.jrnl and
humans.jrnl

using the following

$journal = "humans.jrnl"
$journal.ToLower().TrimEnd(".jrnl")

This works fine with humans but human returns the string ‘huma’. What is the correct way to accomplish this?

TrimEnd() technically takes an array of single characters, not a string. See https://msdn.microsoft.com/en-us/library/system.string.trimend(v=vs.110).aspx. PowerShell is likely turning “.jrnl” into an array, which means it will remove ., j, r, n, and l from the end. TrimEnd() is a bit more powerful than you might realize.

But for what you’re doing, it’d be much easier just to do a…

$journal = $journal -replace “.jrnl”,“”

Thanks for the reply. I will use the replace function. I find it interesting that TrimEnd is consuming only specific extra characters. I have noticed the behavior with ‘n’ and ‘r’ so maybe it is treating them as ascii codes.
