and I need to grab the 5th occurance of *.LOG (S0000570.LOG). The catch is that the number preceeding the .LOG string will change and the entire line is actually one word (verified this by trying to search for just the word S0000570.LOG using grep -w S0000570.LOG and I got the entire line back). The consistant thing is that the *.LOG string i need will always be 11 characters (such as S0000570.LOG). Can I do this with SED?

*edit* grammer
An awk solution:

awk 'NR==5{print $NF RS}' RS=".LOG" infile
