yeah you make your own lib.sh and then a header you put in every file that looks like
shebang usr bin env bash
script_root = garbage to get PSScriptRoot in bash
. "${script_root}/path_to/lib.sh
setup shellcheck with all rules, only ignore rules per file/file

A little known feature of the #PowerShell switch statement is that it can process a file with the `-File` parameter and the `-Regex` parameter.
That is pretty fast to read and compare a 10K line text file.
@BrucePayette mentioned this when he was on my meetup talking about his new Braid language (sits on top of .NET and PS) and Pattern Matching.
----
$fileName = "$PSScriptRoot\random_text_10k.txt"
$countMap = [ordered]@{a = 0; b = 0; c = 0; d = 0; e = 0 }
$timing = Measure-Command {
switch -Regex -File $fileName {
'^a' { $countMap.a }
'^b' { $countMap.b }
'^c' { $countMap.c }
'^d' { $countMap.d }
'^e' { $countMap.e }
}
}
"Took {0} seconds to read a 10k line file and match" -f $timing.TotalSeconds
$countMap
---- Result ----
Took 0.0584586 seconds to read a 10k line file and match
Name Value
---- -----
a 1944
b 2022
c 1993
d 2033
e 2008

$psscriptroot is split-path -parent $myinvocation.mycommand.definition for the lazy. And I’m ok with it.

Could I suggest using $psscriptroot and the path to the file instead of all the directory changing?

Apart from the module name change, Measure-Script now supports:
- Scripts w/ v4/v5 language features
- $PSCommandPath/$PSScriptRoot resolution in file-based scripts
- Caller-scoped scriptblock execution

because cmd.exe processes .BAT files line by line (no read file lock) you can just delete yourself :-) fs0 is the path to the bat file
PS is more like
Remove-Item $PSScriptRoot -Force -Confirm:$JustDOIT

When running InModuleScope, you can use $PSScriptRoot or $PSCommandPath to get path to the >test script<. And $script:PSScriptRoot or $script:PSCommandPath to get path to the tested >module<. #powershell #pester #psPester @PSPester

I usually do this `. $PSScriptRoot\Code.ps1` unless I need to be PSv2 compatible. Or did you mean something different?

@MSH_Dave "You can't use $PSScriptRoot at the command line. That variable is only set when you're executing a ps1 or psm1 file." FACT! 👍
