Problem
How would you print just the 10th line of a file?
For 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
即输出第十行,又是bash题。
Bash
sed -n 10p file.txt
分析
没什么可说的。题目要求3种以上解法。不过对于bash题,暂时以学习了解为主。
