Bash 带Cat的管道

我似乎不知道在这里失败了。我打算将一个文件从csv文件读取到Postgres DB。 我有这个

cat Master.csv.2014-06-04-13-18-52  | tr \" \ | psql -U dev test_db

这是我正在使用的CSV文件：

"9090","1000","5000","default","2014-06-02 23:38:39","2014-06-02 23:38:39","2014-06-02 23:38:42","3","3","NORMAL_CLEARING","c8e1c005-3d32-460d-8188-21c5a841f33a","","1000","GSM","GSM"

我得到一份工作

ERROR:  syntax error at or near "9090"

请问我做错了什么？是否有可行的Bash替代方案？

在传递您的CSV文件后：

"9090","1000","5000","default","2014-06-02 23:38:39","2014-06-02 23:38:39","2014-06-02 23:38:42","3","3","NORMAL_CLEARING","c8e1c005-3d32-460d-8188-21c5a841f33a","","1000","GSM","GSM"
"1000","1000","5000","default","2014-06-02 23:39:59","2014-06-02 23:39:59","2014-06-02 23:40:09","10","10","NORMAL_CLEARING","f9248341-bbec-49ed-af93-a574861cca3b","","1000","GSM","GSM"
"1000","1000","5000","default","2014-06-02 23:40:22","2014-06-02 23:40:22","2014-06-02 23:40:52","30","30","NORMAL_CLEARING","49f88527-0d1e-4511-a8b8-52aac64205e9","","1000","GSM","GSM"

通过

tr

命令，您可以按预期将引号变成空格：

 9090 , 1000 , 5000 , default , 2014-06-02 23:38:39 , 2014-06-02 23:38:39 , 2014-06-02 23:38:42 , 3 , 3 , NORMAL_CLEARING , c8e1c005-3d32-460d-8188-21c5a841f33a ,  , 1000 , GSM , GSM 
 1000 , 1000 , 5000 , default , 2014-06-02 23:39:59 , 2014-06-02 23:39:59 , 2014-06-02 23:40:09 , 10 , 10 , NORMAL_CLEARING , f9248341-bbec-49ed-af93-a574861cca3b ,  , 1000 , GSM , GSM 
 1000 , 1000 , 5000 , default , 2014-06-02 23:40:22 , 2014-06-02 23:40:22 , 2014-06-02 23:40:52 , 30 , 30 , NORMAL_CLEARING , 49f88527-0d1e-4511-a8b8-52aac64205e9 ,  , 1000 , GSM , GSM 

然而，

psql

不知道如何处理这些行，它需要SQL命令

如果您的目的是使用该数据创建行，则需要进行更多操作，以将它们转换为正确的SQL语句。这意味着，除其他外，将

“

字符替换为

”

（或删除数字列的引号），并将其转换为以下形式：

insert into sometable (column1, column2) values (X)

其中，

X

是您已经拥有的字段值，但如上所述使用单引号（或无引号）

以更简单的文件示例为例：

"9090","1000","2000"
"3000","4000","5000"
"6000","7000","8000"

您可以使用以下内容：

cat Master.csv
    | tr '"' "'"
    | sed -e 's/^/insert into mytable(col1,col2,col3) values (/'
          -e 's/$/);/'

（在一行上）要获取脚本文件：

insert into mytable(col1,col2,col3) values ('9090','1000','2000');
insert into mytable(col1,col2,col3) values ('3000','4000','5000');
insert into mytable(col1,col2,col3) values ('6000','7000','8000');

---

然后将其传递到

psql

以执行命令。

而不是简单地显示命令，还可以指示您试图实现的目标（特别是使用

tr

）。此外，

cat

不是一个内置的shell。它是一个二进制文件，可以与任何shell一起使用，因此

bash cat

没有多大意义。@devnull tr用于将双引号转换为单引号，以与PostgreSQL兼容。日志将提供给插入查询。如果需要将双引号转换为单引号，请使用

tr''“”

谢谢您的更正。做了更改，但仍然收到相同的错误谢谢！，虽然我已经解决了这个问题。我从你的回答中学到了很多。将其标记为正确以供参考！。非常感谢。
