Print all the lines between 10 and 20 of a file

Similarly, if you want to print from 10 to the end of line you can use: sed -n '10,$p' filename

This is especially useful if you are dealing with a large file. Sometimes you just want to extract a sample without opening the entire file.

Efficiently print a line deep in a huge log file

Sed stops parsing at the match and so is much more effecient than piping head into tail or similar. Grab a line range using

sed '999995,1000005!d' < my_massive_file
