得分: 1
获取第17行：
head -17 file | tail -1
获取第99行：
tail -2 file | head -1
用分号组合这些命令：
head -17 file | tail -1 ; tail -2 file | head -1
英文:
Get the 17th line:
head -17 file | tail -1
Get the 99th line:
tail -2 file | head -1
Combine the commands with a semicolon:
head -17 file | tail -1 ; tail -2 file | head -1
