Because that would turn a line of "fred" into "foofred". :)

Too broad -- it will match the null string. (* means "zero or more
instances of" whatever preceded it.)
Best RE I know for integers is
[1-9]

Yes. In regex, * means "any amount of", if I remember correctly.
So you don't have to specify precisely how many numbers there
are.
How many lights? :-)

Gang,
I was tried to find Jeffrey Friedl's email to figure out some quick
regex when it struck me that the list can clue me in [[I have
figured this out myself several times--well, 3 or 4 anyway--but it
was more trial/error than I need.]]
I have a file with ints from 0 to some N. What is th

I know thins is not the place but I know one of you know this one off the
top of your head.
I have:
$list = "dog 1 1 1 cat 2 1 snake 111"
and I want to end up with:
dog 1 cat 2 snake 1
I thought
$list =~ s/ \d \d/ \d/g;
would do the trick, but that gives me:
dog d 1 1 cat d snake d 1
Thanks,
Rog
I know thins is not the place but I know one of you know this one off the
top of your head.
I have:
$list = "dog 1 1 1 cat 2 1 snake 111"
and I want to end up with:
dog 1 cat 2 snake 1
I thought
$list =~ s/ \d \d/ \d/g;
would do the trick, but that gives me:
dog d 1 1 cat d snake d 1

I have:

and I want to end up with:
