Sometimes, I want to extract some continuous lines from a file, e.g. line 10 to line 100. I was thinking whether there is any linux command to do that. Unfortunately, I did not find the command in vanilla Linux distros. Suddenly, I found that it can achieved by combining commands head and tail.
Let's say you want to extract line min to line max, both inclusive.
Calculate nlines=(max-min+1). Then use following command:
cat <filename>|head -n <max>|tail -n <nlines>
