I know, I’m opening this can of worms again. You either love or hate the backtick in
PowerShell. The little thing is so
awesome, but so hard to see. It is no secret
that I use it for line continuation. I
have a set of rules that I follow to allow me to use it without issues. Here they are.
At the end of the line:
o
Press SPACE
o
Press the BACKTICK
o
Press ENTER
o
Indent the first continued line
o Do not use it on the last line of the command
Here is a command without line continuation:
New-ADFineGrainedPasswordPolicy -Name "Group1PSO" -Precedence 10 -ComplexityEnabled $True -Description "PSO for Group
1" -DisplayName"Group1PSO" -LockoutDuration "0.12:00:00" -LockoutObservationWindow "0.00:15:00" -LockoutThreshold 3 -MaxPasswordAge "10.00:00:00" -MinPasswordAge "1.00:00:00" -MinPasswordLength 8 -PasswordHistoryCount 10 -ReversibleEncryptionEnabled $False
Here is the same command following my rules.
New-ADFineGrainedPasswordPolicy -Name "Group1PSO" `
-Precedence 10 `
-ComplexityEnabled $True `
-Description "PSO for Group
1" `
-DisplayName "Group1PSO" `
-LockoutDuration "0.12:00:00" `
-LockoutObservationWindow "0.00:15:00" `
-LockoutThreshold 3 `
-MaxPasswordAge "10.00:00:00" `
-MinPasswordAge "1.00:00:00" `
-MinPasswordLength 8 `
-PasswordHistoryCount 10 `
-ReversibleEncryptionEnabled $False
I need to add another one.
Based on teaching PowerShell so many times, I need to make a change to the colors that
I use in the PowerShell ISE and SAPIEN PowerShell studio. I need to change the color of parameters so
they are not so close to the color of a cmdlet.
Take a look at both of these.

Normal

Changed parameter color

New-ADFineGrainedPasswordPolicy `
-Name "Group1PSO"
`
-Precedence 10
-ComplexityEnabled $True
`
-Description "PSO
for Group 1"
|
New-ADFineGrainedPasswordPolicy `
-Name "Group1PSO"
`
-Precedence 10
-ComplexityEnabled $True
`
-Description "PSO
for Group 1"

On the third line, I forgot to use a backtick. On the example on the left, it is very hard to
see the parameter on line 4 is not the correct color.
In the example on the right, it is. This makes it more obvious if you broke on of my rules and makes debugging easier. These are the color settings
that I am now using in my PowerShell classes.
PowerShell ISE:
In SAPIEN PowerShell Studio.
Click the Home
tab and the Options on the far
right.
I hope the PowerShell teams adds some type of splatting that
allows for TAB completion. That would
get me to move away from the backtick.
But until then, I will continue to use it with my rules in place. To learn more about line continuation in
