First look at powershell 6.1.0
|
|
|
|
Powershell [6.1.0][1] dropped yesterday. Here is my quick look.
|
|
|
|
## New Commands
|
|
|
|
`Get-Command | Measure-Object` on each version:
|
|
|
|
Version 6.0.4 had 316 commands, while 6.1.0 has 323 commands. Comparing a list
|
|
of commands:
|
|
|
|
On 6.0.4: `gcm | select -exp name > 6.0.4.txt` and the same on 6.1.0, then to
|
|
compare:
|
|
|
|
compare-object (gc ./6.0.4.txt) (gc ./6.1.0.txt)
|
|

|
|
|
Firstly, yay for `Test-Connection`. I had to reimplement that one by parsing
|
|
results from `ping` previously to make some of my windows modules work on PS
|
|
core. Start-ThreadJob looks interesting and I can't wait to see what the
|
|
Markdown cmdlets do.
|
|
|
|
I'll look more at these new commands later, but while I was running
|
|
Get-Command, I thought I'd see if there were any generic performance
|
|
improvements in 6.1.0 release.
|
|
|
|
On 6.0.4:
|
|
|
|
PS /home/harrisj> measure-command {gcm | select -exp name}

|
|
A modest speed boost. Definitely appreciated on the old RPI 2 that hosts this
|
|
site.
|
|
|
|
### Kicking the tires on new command
|
|
|
|
## Show-Markdown
|
|
|
|
I gave this a quick try and it colour highlighted and shows a preview of the
|
|
markdown in the terminal window. It also had a -UseBrowser parameter which
|
|
writes a tmp html and open's it in the browser. Pretty neat.
|
|
|
|
## ConvertFrom-Markdown
|
|
|
|
What you'd expect, this converts a Markdown file to html to stdout or to a
|
|
file if specified. Who knows, I might see if I can get this site to work using
|
|
this implementation of Markdown. Currently I'm using the Markdown.pl from
|
|
Gruber.
|
|
|
|
## Get-ExperimentalFeature
|
|
|
|
Does nothing on the RPI and MacOS. Will have to spin this up on Windows and
|
|
update this article
|
|
|
|
## Test-Json
|
|
|
|
Just ran this over a json file I use in one of my projects:
|
|
|
|
Test-Json -Json (gc ./Template.json -raw)
|
|
True
|
|
|
|
## Start-ThreadJob
|
|
|
|
This might take a bit more time to find the true value of it, but I quickly
|
|
tried my simultaneous ping test with this and it spawned a number of PSJobs
|
|
with a PSJobTypeName of ThreadJob.
|
|
|
|
### Closing thouhghts
|
|
|
|
Thats it for now. I've heard this release focused alot on bringing Windows
|
|
cmdlets back for Windows, so not-so-much in this one for the \*nixes. Still
|
|
an improvement either way
