Vista - replace

Hej Powershell team.

In gui-help replace can be defined as - a specified number of times.
But how should i do, if i only will change the first space and not the other
space
in the following example ???

${C:\powerstart.txt} -replace ' ',';' > C:\powerstart1.txt

I need a real reference manual !!
--------------------------------------------------------------------

Replace

Definition: Returns a string in which a specified substring has been replaced
with another substring a specified number of times.

$a = "bxnxnx"
$a = $a -replace("x","a")

# to replace the first space in each line of the file
$pattern = '(.*?)( )(.*)'

(get-content C:\powerstart.txt) -replace $pattern,'$1;$3' > C:\powerstart1.txt

# to replace the first space in the file
# pipe its content to out-string and
# set the single line option in the regex

$pattern = '(?s)(.*?)( )(.*)'
(get-content C:\powerstart.txt | out-string) -replace $pattern,'$1;$3' > C:\powerstart1.txt

Thanks for the help i got.
My final code was:

$pattern = '(?s)(.*?)( )(.*)'
${C:\powerstart.txt} -replace $pattern,'$1;$3' > C:\powerstart1.txt

And it works fine
