Dear Monks,

perl -e '
   $string="X*X*X*X"; \
   $NEW=20;           \
   $string =~ s/(^|[\*])X([\*]|$)/${1}${NEW}${2}/g; \
   print "$string\n";'

[download]

will gives :

20*X*20*X

It seems that after first match, the first '*' which was used by 1st match, doesn't count for the 2nd match ..

Is there any modifier or another way to replace all the 'X' at once ? any trick without executing this line twice ?

Thank you very much !

edit: Thank you all for your answers, the ?= works beautiful.. very useful! :D
