Silly question with Unix

Handling large files:
1. Suppose you have very large files and it is zipped. Now you want to track some particular line. You cannot use simply the head and tail. for example i have one files wiht 59023435 lines. Now my simulator failed and reported some problem is there in line number 23694538. How do you access this line ?

Ans : Take the help of one liner awk.
vikrant@alu.hyd /u/vikrant/data/alu/2007/04/10> zcat 20070410.gz | wc -l
59023435
vikrant@alu.hyd /u/vikrant/data/2007/04/10> zcat 20070410.gz | gawk '{if(NR >23694535 && NR < 23694540) print;}'
