echo 换行不换行

echo换行输出需要转义符 -e

看以下例子：

1 echo -e "It is the first line." >> a; echo -e "It is the second line.\c" >> a; echo -e "It is the third line." >> a; echo -e "\nIt is the forth line." >> a

输出：

It is the first line. //默认换行 It is the second line.It is the third line. //第二行指定不换行，因此第三行紧跟第二行 It is the forth line. //第三行默认换行，而且第四行前制定换行，因此中间空了一行
