Tenth Line

Solution

Using sed

This doc (opens new window) states that, "p" is the print command. If sed weren't started with an "-n" option, the "p" command would duplicate the input. The "-n" option turns off printing unless you request it.

sed -n "10 p" file.txt

Using awk

This doc (opens new window) states that, NR is the number of records, or the line number.

awk 'NR==10{print; exit}' file.txt
