编写 Bash 脚本来编辑 csv 文件

Question

所以我有一个像这样的csv文件

Sam,0.0.1
Smith,0.0.1

我想追加

Ria,0.0.1

最终结果应该是这样的

Sam,0.0.1
Smith,0.0.1
Ria,0.0.1

我使用的命令：

sed -i s/\'smith,0.0.1\'/\'smith,0.0.1\',\'Ria,0.01'\'/g <name of csv>

它的作用是

Sam,0.0.1
Smith,0.0.1, Ria,0.0.1

Answer 1

尝试在Ria之前添加\n 。

命令应该是：

sed -i s/'smith,0.0.1'/'smith,0.0.1','\nRia,0.01''/g

\n表示换行。

Answer 2

像这样：

sed -i '$a Ria,0.0.1' file

• $代表最后一行
• a代表追加

Answer 3

你为什么不这样做：

echo "Ria,0.0.1" >> csv_file
