Powershell - Trim

PowerShell Help

Hi to all,

I am trying to find out away how to trim a string from a specific character.

let say I have a package name: Baybon_v1.0

How can I trim this to show only: Babylon

Another example:

Microsoft office professional_v2016

Would like to trim the text starting “_”

The result should be:

Microsoft office professional

Thank you so much for your time and help

This example is hardcoded but it works

[string] $str1 = "Baybon_v1.0"

$str1.TrimEnd("_v1.0")

OUTPUT = Baybon

$str1 = "Microsoft office professional_v2016"

$str1.TrimEnd("_v2016")

OUTPUT = Microsoft office professional

 

If you want this to be generic, such as function that works for all cases, consider wildcards or regexes in

combination with String.Trim()

<p style=“text-align: left;”>Another option would be to use Split. You can split string by specific character and create array.</p>
On you case you will split by _ and will use the first element of that array.

$str1 = "Baybon_v1.0"

$str1.split('_')[0]

Hope that helps

Few more options

$text = 'Microsoft office professional_v2016'

$text -replace '_.+'

$text -split '_' | select -First 1

($text -split '_')[0]

If($text -match '.+(?=_)'){$matches.0}
