Title: RE: [Perl-unix-users] search for a particular string in a file

A couple questions:

 

- will the "small" file always have the same number of lines?

- is there are certain line number on which the match may appear? Or could it be anywhere other than header/footer?

- is there a chance that it could match more than one? If so, how do you want to handle it? Only write to the first file? Or write to each file for each match?

Subject: Create three different files based on search string in the input file

Hi,

I have a small file. I want to read this file and create three different files based on a string found.

For example my small file is like this.

 

this is the header line

this too is header line

----

---

search strings are here abc xyz mlt

some more are here pqr jkl

some more are asd frg supp

----

---

this is footer

this is also footer...

 

Now the three different output files  should contain all the header and footer lines. But if "abc" or "xyz" or "mlt" is found on a line it should go to out file A only, if string "pqr" or "jkl" is found it should go to output file B only and if string "frg" or "supp" is found on a line it should go to out put file C only.

 

Can any one help me on how to do this easily using perl code.

 

Note: I am new to PERL.

 

Thanx..
