seq can produce the same thing as Perl's ... operator.

Optionally, one can use {1..50} instead of seq. E.g. for i in {1..50} ; do echo Iteration $i ; done

sed -n '10,20p' <filename>

Functions: sed

Up

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.
