Powershell Split based on new line-CodePudding

I have a text file which I import using Get-Content It looks like this:

aago go sdf
bbbgo go sdf gojh
go

zzzz bbb
go

sdkfgo go sdfd
go

I want to -split it based on 'go' which is single liner "go", aka i want 3 array items only. So -split 'go' won't work.

How to specify delimiter for split where the only item in line in 'go', OR where after 'go' there is a new line?

So output I expect is this

$output[0]=
"aago go sdf
bbbgo go sdf gojh
"

$output[1]=
"zzzz bbb
"

$output[2]=
"sdkfgo go sdfd
"

CodePudding user response：

# Sample input, defined via a verbatim here-string.
$str = @'
aago go sdf
bbbgo go sdf gojh
go

zzzz bbb
go

sdkfgo go sdfd
go
'@ 

$str -split '(?m)^go\s*$' -ne '' |  # Split as desired.
  ForEach-Object { "«$_»" }         # Visualize the results

For an explanation of the regex used with the -split operator above and the ability to experiment with it, see this regex101.com page.

Output:

«aago go sdf
bbbgo go sdf gojh
»
«
zzzz bbb
»
«
sdkfgo go sdfd
