Also note the required The command above uses a streamlined approach to replacement:? Improve this answer. Replace is a method of. NET type [string] , not an operator.
Unlike PowerShell's -replace operator, which uses regular expressions,. Replace performs literal substring replacements, which I suspect may be neha's problem: after an initial successful run of the script, the literal doesn't match anymore. To put it differently: Even though your code is more concise and more efficient, it is in essence the same as the OP's and doesn't explain the intermittent failures.
The only - negligible - functional difference is that the. I will try your script but confused why mine is not working! Any other way around? Something like convince PowerShell not to swallow whole file, but rather bite by pieces? I'm don't know how to get around doing the get-content, but I have to wonder if using select-string to find the array indexes of all the lines that need changed, and then updating those lines by index instead of doing the foreach-object on the whole file.
Not sure if I understand your idea… Could you post a little code snippet, please? BTW: There is a difference between:. Using get-content and piping to foreach-object doesn't read the whole file swallow , it reads it line by line and in a streaming way passes each line to foreach-object. Reading the whole file into memory is not the best way to handle that kind of situation imo. If you want to replace and save then using the above is my recommendation.

The first uses braces while the latter uses parentheses. These are just syntax differences. Final Final Script: :.

Is there a way to get this to go through and open each file edit and then resave as the same file? I'm migrating printers and am new to powershell so cant for the life of me figure out how to edit the script to get ti to do what I need it to do.
It has only been closed for a couple of months, so I figured the people who were in tis thread may still be able to help. I opened a new topic but found this afterwards, and was just asking for clarification on the script. I'll grab the script and add it to my new topic and ask for assistance there. Yes - it would be better to have a new question since your question has to be different else the answer here would have been the answer you need.
