I have a simple file as such:

30: 400 650 710

I have a one-liner that removes the number before the colon and substitutes any following number with this removed number.

Here is the one liner: 

perl -p -e 's/^([0-9]+)://g;$a=$1;s/\d+/$a/g' $CONF_FILE

[download]
I run on Solaris9 and here is what I get (the desired result):

 30 30 30

On RHAS I get nothing returned. From intial debugging it appears the number before the colon is removed but not captured.

I say this because I try this modified one-liner to print the captured result: 

perl -p -e 's/^([0-9]+)://g;print $1' $CONF_FILE

[download]
On SUN I see the value printed (before the returned line of course):

30 400 650 710

But on Linux I do not see the captured value:

 400 650 710

I need this to be portable - if anyone would be gracious enough to bestow any ideas upon me I would appreciate it very much!
