how to find last word in a line?? 2

[rao12]

Hi,

I have a text file with each line having variable number of words..
how do i print the first few words and last word of a line in to an output file.
I was doing with $NF for the last feild in shell scripts how do i do it in perl.

sample text file
====================
hgahgdhsgd hgshdgshd jhkjjkj lklk 9898
ghsgh t6523 8787 87jhj jhjshjhh
jjkjkj hjhjjhh 0000

i would like first few words and the last word in an output file to process further.


Thanks
Rao

# with lines in @lines

foreach $line (@lines)
{
$line =~ /^(.*?\b.*?\b).*\b(.*?\b.*?)$/;
$first_two_words = $1;
$last_two_words = $2;
}


The up caret pins the regex to the start of the line. A dot (.) is a wild card. A dot followed by a star is any number of wild cards. A dot star question_mark \b is any number of wild cards up to the next word boundary (\b). There is a .* in the middle with no ? that will suck up the middle of the line. The dollar sign at the end pins the reges match to the end of the string(line).

'just one way.

/^\b(.+?)\b.+?\b(.+?)\b$/g;
print NEWFILE &quot;$1 $2\n&quot;;
