从字符串 PowerShell 中删除文本

Question

I´m vacation hangover and cannot wrap my head around an Powershell dilemma!

I´ve a script where I get the following output below which is saved to a variable $ScanOutput . Now I want to filter out and only keep the code after ExitCode= (Can be 500 or 0). How can I filter out everything before and after 500 (which can be other codes, not static).

@{StdOut=Checking for updates...
Determining available updates...
Check for updates completed
Number of applicable updates for the current system configuration: 0
No updates available.
Execution completed.
Program exited with return code: 500
; ExitCode=500; StdErr=}

Thanks in advance, Kind regards, JN

Answer 1

You can simply use Select-String :

($ScanOutput | Select-String -Pattern 'ExitCode=(\d+)').Matches.Groups[1].Value
500

Answer 2

Many ways to skin a cat, assuming the delimiter ; is consistently placed. Might be nice to test which method is fastest:

($scanoutput -split ';')[1].Trim()
ExitCode=500

Answer 3

Since JNilsson came back and said that I actually was correct in my statement that it was hash table I will add back my answer to help others with similar problem.

The object

@{StdOut=Checking for updates... Determining available updates... Check for updates completed Number of applicable updates for the current system configuration: 0 No updates available. Execution completed. Program exited with return code: 500 ; ExitCode=500; StdErr=}

To get the ExitCode from the object simply make sure to assign it to a variable, in my case $hash then you can get the value by doing this:

$hash.ExitCode
