At first you need to ensure that your cgi script has the privileges to
write/modify the file "/opt/myfile".
Then you may call:
system "perl -pi -e ..."
to do the things you wanted in the cgi script.
But I think the good way is something like:
# copy the old content in that file to an array
open FILE,"/opt/myfile" or die $!;
my @file = <FILE>;
close FILE;
# re-write the new content to the file
open FILE,">","/opt/myfile" or die $!;
for (@file) {
s/192.168.1.1/10.0.0.1/g;
print FILE,$_;
}
close FILE;
Is it?
Hope this helps.
