query on how to search for a line and read 4th word from that line

jaggesh · #1 (**permalink**) 07-01-2008

Assume I have a text file as below:

me
con pi
ind ken
pras ur
me
con rome
ind kent
pras urs
pintu
con mys
ind pan
pras ki
con kit
ind sys

My requirement,

I need to search for "con rome" and if exists, then print 4th word from rome, i.e in above example, since "con rome" exist in one of the line, I need to print "urs". Please let me know how to do it using awk or sed commands.

Edit: Forget what I posted - I read "field" instead of word.

One solution:

Code:

awk '/con rome/,/\*/ {print}' file | awk 'NR==3 {print $2}'

If Perl is acceptable:

Code:

perl -0777 -ne'print $1,"\n" while /con rome\s*(?:\w+\s*){3}(\w+)/g' input

If the input does not contain empty lines:

Code:

perl -00 -ne'print $1,"\n" while /con rome\s*(?:\w+\s*){3}(\w+)/g' input
