i Daniel,
thanks for your great answer. I like your regex but strangely in Cfengine
(unlike in a testing application ("the regex coach") it will not work.
(Cfengine just puts the first linie into the array and if the first linie of
the data file ist NOT fitting to the regex it will not put any line into the
array)
I have some questions:
Will cfengine view the file as ONE long line or will it use the file
"line-by-line".
For me it seems like in Cfengine ^ and $ representing "start of text" and "end
of text" and NOT "start of line" and "end of line".
That might be the reason why your the answer of Daniel is not working.
Is there a possibility to "tell" cfengine to use ^ and $ as start of line and
end of line ancor?
Or is this not a Cfengine issue? Is it due to my little knowledge about regexes?
After a lot of trying i am really lost in there :(
-Joe
