Hello Masters,
I want to find a pattern in all the files. Then i want to replace an exact specified pattern from every file. I am using the below command. However, the line "s#<--/--a8300-->.*?<--/a8300-->.##isg $_;" gives error. Could you please tell me, how can i use the replace command for all the files. Doesn't perl allow us to give the path of the file which we want to replace. There must be a way in perl and i am waiting for the masters to let us all know how to do that.

Thank You in advance. 

#!root/perl5/perlbrew/perls/perl-5.13.4/bin/perl
use feature say;

#empty the file
`>affectedlist.txt;`

#will give the list of files which contains the pattern
`grep -irl "<--/--a8300-->" ./* >> affectedlist.txt`; 

open(FILE,"<","affectedlist.txt") or die "Couldn't open file.$!";
foreach (<FILE>)
{
chomp($_);     
#Change filenames to unix readable  e.g Nayab Rahil to Nayab\ Rahil
$_=~ s#\s+#\\ #sg;                       

#replace the pattern on every file.
s#<--/--a8300-->.*?<--/a8300-->.##isg $_;     #$_ is my filename

}

Please help me masters also if you can provide me good links to understand perl pattern matching. It would be really great for us.
Thanks again for your time.
