1、命令行打开cut.csv文件,vi cut.csv,并设置打开行号:set nu 内容如下：
1 golonglee, golonglee@163.com youname
2 golonglee, golonglee@163.com youname
3 golonglee, golonglee@163.com youname
4 golonglee, golonglee@163.com youname
5 golonglee, golonglee@163.com youname
6 golonglee, golonglee@163.com youname
7 golonglee, golonglee@163.com youname
8 golonglee, golonglee@163.com youname
9 golonglee, golonglee@163.com youname
10 golonglee, golonglee@163.com youname
11 golonglee, golonglee@163.com youname
12 golonglee, golonglee@163.com youname
13 golonglee, golonglee@163.com youname
14 golonglee, golonglee@163.com youname
15 golonglee, golonglee@163.com youname
16 golonglee, golonglee@163.com youname
各讨哨17 golonglee, golonglee@163.com youname
18 golonglee, golonglee@163.com youname
19 golonglee, golonglee@163.com youname
20 golonglee, golonglee@163.com youname
21 golonglee, golonglee@163.com youname
2、输入脂鬼英文的冒号: 然后输入 nonu即可取消显示行号
3、之前的经验里面说过使用cut -f3 -d, +文蕉肺件名，可以截取某一段
4、截取后的效果
5、用vi cut.tab打开要编辑的文件cut.tab
6、输入如下命令:%s+,+:+并回车
7、在命令模式下，输入
:%s+,+:+并回车，看到cut.csv中的逗号,都已经被冒号:替换，内容如下：
1 golonglee: golonglee@163.com youname
2 golonglee: golonglee@163.com youname
3 golonglee: golonglee@163.com youname
4 golonglee: golonglee@163.com youname
5 golonglee: golonglee@163.com youname
6 golonglee: golonglee@163.com youname
7 golonglee: golonglee@163.com youname
8 golonglee: golonglee@163.com youname
9 golonglee: golonglee@163.com youname
10 golonglee: golonglee@163.com youname
11 golonglee: golonglee@163.com youname
12 golonglee: golonglee@163.com youname
13 golonglee: golonglee@163.com youname
14 golonglee: golonglee@163.com youname
15 golonglee: golonglee@163.com youname
16 golonglee: golonglee@163.com youname
17 golonglee: golonglee@163.com youname
18 golonglee: golonglee@163.com youname
19 golonglee: golonglee@163.com youname
20 golonglee: golonglee@163.com youname
21 golonglee: golonglee@163.com youname
