Stallion,

Put your contents in monks.txt and give the following one liner.

perl -p -i -e "s/^macros(.)*/macros\ regex/g" monks.txt

    No need for parentheses; nor to escape the space; nor for the 'g' modifier - '.*' will gobble everything up, thus there can be only one match. So: 

    perl -p -i -e "s/^macros.*/macros regex/" monks.txt

# or

perl -p -i -e "s/^macros\K.*/ regex/" monks.txt

    The grouping is not really required. This works pretty fine: 
    s/^macros.*/macros regex/
