I have a script that's supposed to change a value in a file on multiple servers
it works and all, but as I would like to understand and learn what each part does(99.9 % i do)
I cannot understand what this little $ sign does and why do I need it:
-replace 'MaxActiveMovesPerSourceMDB = "5"$','MaxActiveMovesPerSourceMDB = "50"' `
why do I need the $ sign before I close the value i want to replace with a ' ?
PowerShell's -replace operator uses regular expressions for its first argument. In a regex, the $ character means to only match the pattern at the end of the string (or at the end of a line, depending on how you're using it.) There's an about_Regular_Expressions help file in PowerShell that can help you get started with that.
Thanks for a blazing fast reply:)
I only saw one documentation of this '$ sign but I wasn't sure if it even fits what I see here cause I got some value enclosed with 'value1' to replace with another value 'value2'
in my case I think im replacing/matching whatever is inside these ' ' so that's why I don't understand why this $ is needed:)
but maybe its just faster this way it match "end characters instead of the whole value?
I wonder what "end character mean anyway:)? 1?3? or just from the end to start whatever matches?
sorry for the many questions
