I am looking to match all instances of (s:)(\d{1,}:)\"(string)\"; to get something like this:
s:14:override_title
s:18:show_readmore_link
s:3:547
This line with or without /g prints only the first instances:
perl -nle 'print "$1 $2 $3" if /(s:)(\d{1,}:)\\"(.*?)\\";/g' tmp.txt
s:14:override_title
I suppose I can try to put this in a perl script putting all matches into an array, but am hoping to do this using a one-liner (-: What am I missing?
Mac OS X 10.7.5, perl 5.12.3.

The metacharacter \b is an anchor like the caret and the dollar sign. It matches at a position that is called a “word boundary”. This match is zero-length.
In general, Perl uses a backtrack regex engine. Such an engine is flexible, easy to implement and very fast on a subset of regex. However, for other types of regex, for example when there is the | operator, it may become very slow.
E.g. (? i-sm) turns on case insensitivity, and turns off both single-line mode and multi-line mode.
Use /m , /s , or both as pattern modifiers. /s lets . match newline (normally it doesn't). If the string had more than one line in it, then /foo. *bar/s could match a "foo" on one line and a "bar" on a following line.
It's seem you have only line, so have a try with:
perl -nle 'print "$1 $2 $3" while(/.*?(s:)(\d{1,}:)\\"(.*?)\\";/g)' tmp.txt
