Hi, i am reading a text file. and my code looks like below: 
open FH, "$INPUT_DIR/$input_file" or die "Couldn't Open File: $!";
 
while ( <FH> ) {
 
chomp;
 
my ($s, $a, $c, $r) = (split / [, \t]/, $_);

the split fucntion process the comma and tab delimited now. Input file: 
process:
 
clientserver,00001,AIT,SOURCE
 clientserver        00001     AIT       SOURCE
 
error:
 
clientserve|00001|AIT|SOURCE

split should die if it finds the pipe and it should process if it finds comma or tab delimited.
