Shell Programming and Scripting

Hi I have some script like this:

perl -i -p0e 's/"keyword1-.*?"/"keyword2"/s' file

to replace some keyword, but it replaces only the first instance of the keyword
how can i get it to replace all instances?
thanks!

To replace for all instances you need to add the global option "g"

Trying doing it this way:
perl -i -p0e 's/"keyword1-.*?"/"keyword2"/g' file

You can also refer to the blogspot

for further clarifications regarding Perl.

okay thanks
what did the "s" mean?

also what does the p0e mean?
what would -pe without the 0 mean?
