The original problem is https://leetcode.com/problems/tenth-line/.
This is a basic application of bash: just get the 10th line from a file. Many methods can solve this simple question.
Solution: using bash control structures, conditional tests
#!/bin/bash let count=0 while read line || [[ -n "$line" ]] do name=$line ((count++)) # echo $count, $line, $name if [ "$count" -eq "10" ] then echo $name fi done<file.txt
Solution: using sed
sed -n '10p' file.txt
Solution: using awk
awk 'NR==10' file.txt
