Given a text file file.txt, print just the 10th line of the file.

Example:

Assume that file.txt has the following content:

Line 1
Line 2
Line 3
Line 4
Line 5
Line 6
Line 7
Line 8
Line 9
Line 10

Your script should output the tenth line, which is:

Line 10

#从第10行开始显示，然后取第一行
tail -n +10 file.txt | head -n 1

#打印第10行
sed -n 10p file.txt

awk ‘NR==10 {print $0}‘ file.txt

awk ‘NR==10 ‘ file.txt

cnt=0
while read line 
do
    let cnt++
    if [ $cnt -eq 10 ];then
      echo $line
      exit 0
    fi
done < file.txt
