then need to modify,

Quote:
print "$split_arr[2]";
as

Code:
print "$split_arr[$#split_arr]";

Question:

I think anbu23's solution is straight and easier too, I am not sure why do you say its not working. But choice is always yours, just a thought Smilie

Hi Matrix,

Your code only works if the desired value is the last term of a row where ddd exist.
If the number of spaces is random between every term, is there any thing we can do to change the condition of spilt portion -> @split_arr = split(/ /, $_);. Any thing to indicate random num of spacing as 1 space ?

And in perl, can we add in some nawk fucntions?
eg nawk -f xxx_awk file

A kind of solution was given based on your input.

For the search pattern 'ddd' your request was to print 'fff' which is the third term in the line.

Since there could be any number of spaces in between terms, it is necessary to extract only the last term in the line as a pattern.

Hence the recent solution.

It would be easier if you could post some more examples.

Sorry with that! Smilie

Try this
Code:
@split_arr = split(/ +/, $_);

Hi Anbu,

I just found out that when there are spaces in front of "ddd", the code won;t work. Any ideas to overcome this problem ?

Input_file:
aaa bbb ccc
[space]ddd eee fff
hhhh pppp kkk jjjj
vvvv mm sss zzz

Code:
#! /opt/third-party/bin/perl

my(@split_arr);

open(FILE, "< file") || die "Unable to open file <$!>\n";

while(<FILE>) {
  s/^ *//;
  @split_arr = split(/ +/, $_);
  if( $split_arr[1] =~ m/ddd/ ) {
    print "$split_arr[$#split_arr]";
  }
}

close(FILE);
exit 0
