This must be an extremely easy question to answer, but much searching has not yielded the answer I seek. I am parsing messages from TSM, which have a format like this:
ANE4954I Total number of objects backed up: 3
I need the "ANE4951I" part of the string, which can be found by simply applying the following regular expression: s/\s.*//
However, I don't wish to change the original text, so I reasoned that as $a=+1
is equivalent to $a=$a+1
, so $a=~s/\s.*//
should be equivalent to $a = $a ~ s/\s.*//
, enabling me to express my needs thus:
$message_id=$message ~ s/\s.*//;
Sadly, this gives me a syntax error. What is the correct syntax for this?
For now, I have coded it like this:
But I suspect there is a better way.
