[powerfulperl]

I have the following code, I need to write the content of a file.txt after searching

for line Local=IN, if found then its o.k if not found then enter the line Local=IN after

the line 'Testing Option OK'.

1. open FH, "<file.txt" ;
2. $/=undef; #set slurp mode
3. $file_contents= <FH>;
4. if (index($file_co ntents, "Local=IN") !=-1) { # file doesn't contain string
5. ($first, $second)=split(/Testion Option OK/, $file_contents) ;
6. $new_file=$firs t."\nTestion Option OK\nLocal=In\n" .$second;
7.# write out the new file here
8. }
9. close FH;

Do you understand what that code is doing?

What did Axweildr say when you asked him to explain the code he gave you?

Do you know how to open a file and write to it?
