File I/O

All,

What is the best way to write output to a file rather then the terminal?
I have played around with set-content and add-content but neither of
them meet my needs. If i use set-content, then each new line that I
write to the file, overwrites the previous line, if I use add-content,
then each time I run the script, it appends it to the file if it already
exists. Is there a way I can create a handle to a file and specify once
what I plan to do with that file so that each time I run the script I
can be sure that I am not appending to a file that already exists unless
that is what I want to do?

Thanks,

Unless I misunderstand you this should do what your looking for:

Command | out-file "c:\logfile.txt" -append

I like functions, so here's one possible approach using a function:

function do-something {
param ($filepath,[switch]$overwrite, $scriptblock)

if ($Overwrite -and (test-path $filepath)) {clear-content $filepath}
&$scriptblock | add-content $filepath
}
