What criteria do you want to use to decide which file to retrieve? Do you know that it will always be called munna-2.0.1? If so, why not just use that instead of calling find.

The opposite of tail is head, so if you want the first line, you can use that.

Here's an awk way of doing it.

Code:

awk 'NR==4' 'file'        #prints line 4
awk 'NR==2||NR==4' 'file' #prints lines 2 and 4
awk 'NR>=2' 'file         #prints line 2 to the end (tail -n +2 'file')
awk 'NR>=2&&NR<=4' file   #prints lines 2-4

you can use head and tail together eg
cat somefile|head -3|tail -1
gives 3rd line only
cat somefile |head -5|tail -2
gets lines 4 and 5
