Start-Transcript Option to Prepend to log file

[exwhyz]

Summary of the new feature / enhancement

As a user I would like an option to prepend transcripts to the top of an existing log file with the most recent transcript appearing on top in a chronological order.

As per Microsoft docs:
-Append
Indicates that this cmdlet adds the new transcript to the end of an existing file.

Start-Transcript -Path "C:\Logs\ps1.log" -Append

Proposed technical implementation details (optional)

So you instead of

#header 
command1, 
command2, 
command3, 
#footer
#header 
command4, 
command5, 
command6, 
#footer

You want

#header 
command4, 
command5, 
command6, 
#footer
#header 
command1, 
command2, 
command3, 
#footer

So the most recent command is not at the top or bottom of the file, and the commands are not in the order they were executed ? It's hard to see that as widely needed. And inserting at the top of a file consumes more resource than appending to the end, so the best way to do this is to log a transcript and when stop transcript is run append the pre-existing logs to the end of it.

I would expect appending to the end of the file to be faster than inserting at the start. And moreso as file size increases. Also, inserting at the start risks data loss. What happens if you are in the middle of an insertion and pwsh or the host crashes?

I can not see the value in this.

Thanks for the feedback, you are right this will be resource intensive. I will use Get-Content with the -Tail switch to give me what I need. Closing this...
