在括号之间的单词周围插入空格

Question

我有一个名为sso-shop-med.txt的文件。

insert into brs.user_shops (user_name, shop_id, is_active, created_date, created_by, last_updated_date, last_updated_by)values('204026601',18, TRUE, current_date,'502675409',current_date,'502675409'); 
insert into brs.user_shops (user_name, shop_id, is_active, created_date, created_by, last_updated_date, last_updated_by)values('502689031',18, TRUE, current_date,'502675409',current_date,'502675409'); 
insert into brs.user_shops (user_name, shop_id, is_active, created_date, created_by, last_updated_date, last_updated_by)values('502683504',18, TRUE, current_date,'502675409',current_date,'502675409'); 
insert into brs.user_shops (user_name, shop_id, is_active, created_date, created_by, last_updated_date, last_updated_by) values ('204009239', 18, TRUE, current_date, '212585704', current_date, '212585704'); 
insert into brs.user_shops (user_name, shop_id, is_active, created_date, created_by, last_updated_date, last_updated_by) values ('204009292', 18, TRUE, current_date, '212585704', current_date, '212585704');

我想在)values(之间添加一个差距，如下所示：) values (

我编写了以下awk命令，但它无法正常工作

awk '{gsub(/")values("/, ") values (" ); print}' sso-shop-med.txt

结果错误：

awk: syntax error in regular expression ")values(" at values("
 source line number 1
 context is
    {gsub(/")values("/, ") values (" >>>  ) <<< 

Answer 1

在正则表达式中，你需要逃避parens并删除引号：

$ cat file
last_updated_by)values('204026601',
last_updated_by)values('502689031',
last_updated_by)values('502683504',
last_updated_by) values ('204009239',
last_updated_by) values ('204009292',

$ awk '{gsub(/\)values\(/, ") values (" ); print}' file
last_updated_by) values ('204026601',
last_updated_by) values ('502689031',
last_updated_by) values ('502683504',
last_updated_by) values ('204009239',
last_updated_by) values ('204009292',

Answer 2

我不确定您的awk版本，但这似乎有效：

awk '{gsub("\\)values\\(", "\) values \(") ; print}'

匝

insert into brs.user_shops (user_name, shop_id, is_active, created_date, created_by, last_updated_date, last_updated_by)values('204026601',18, TRUE, current_date,'502675409',current_date,'502675409');
insert into brs.user_shops (user_name, shop_id, is_active, created_date, created_by, last_updated_date, last_updated_by)values('502689031',18, TRUE, current_date,'502675409',current_date,'502675409');
insert into brs.user_shops (user_name, shop_id, is_active, created_date, created_by, last_updated_date, last_updated_by)values('502683504',18, TRUE, current_date,'502675409',current_date,'502675409');
insert into brs.user_shops (user_name, shop_id, is_active, created_date, created_by, last_updated_date, last_updated_by) values ('204009239', 18, TRUE, current_date, '212585704', current_date, '212585704');
insert into brs.user_shops (user_name, shop_id, is_active, created_date, created_by, last_updated_date, last_updated_by) values ('204009292', 18, TRUE, current_date, '212585704', current_date, '212585704');

成：

insert into brs.user_shops (user_name, shop_id, is_active, created_date, created_by, last_updated_date, last_updated_by) values ('204026601',18, TRUE, current_date,'502675409',current_date,'502675409');
insert into brs.user_shops (user_name, shop_id, is_active, created_date, created_by, last_updated_date, last_updated_by) values ('502689031',18, TRUE, current_date,'502675409',current_date,'502675409');
insert into brs.user_shops (user_name, shop_id, is_active, created_date, created_by, last_updated_date, last_updated_by) values ('502683504',18, TRUE, current_date,'502675409',current_date,'502675409');
insert into brs.user_shops (user_name, shop_id, is_active, created_date, created_by, last_updated_date, last_updated_by) values ('204009239', 18, TRUE, current_date, '212585704', current_date, '212585704');
insert into brs.user_shops (user_name, shop_id, is_active, created_date, created_by, last_updated_date, last_updated_by) values ('204009292', 18, TRUE, current_date, '212585704', current_date, '212585704');

看起来如何？

gawk 方法：

awk '{ gsub(/ *values */," values ",$0) }1' sso-shop-med.txt

输出：

insert into brs.user_shops (user_name, shop_id, is_active, created_date, created_by, last_updated_date, last_updated_by) values ('204026601',18, TRUE, current_date,'502675409',current_date,'502675409'); 
insert into brs.user_shops (user_name, shop_id, is_active, created_date, created_by, last_updated_date, last_updated_by) values ('502689031',18, TRUE, current_date,'502675409',current_date,'502675409'); 
insert into brs.user_shops (user_name, shop_id, is_active, created_date, created_by, last_updated_date, last_updated_by) values ('502683504',18, TRUE, current_date,'502675409',current_date,'502675409'); 
insert into brs.user_shops (user_name, shop_id, is_active, created_date, created_by, last_updated_date, last_updated_by) values ('204009239', 18, TRUE, current_date, '212585704', current_date, '212585704'); 
insert into brs.user_shops (user_name, shop_id, is_active, created_date, created_by, last_updated_date, last_updated_by) values ('204009292', 18, TRUE, current_date, '212585704', current_date, '212585704');

• gsub(/ *values */," values ",$0) - 将 重新排列 values字替换为前导/尾随空格（如果values周围有冗余空格 - 如果在values附近的任何一侧没有空间，它们将被挤压 - 它们将被添加）

Answer 4

您必须使用\转义括号，因为它们是正则表达式中的控制字符。

当我说通常像锤子一样使用awk时，我觉得sed在这里更合适：

sed s/\)values\(/\)\ values\ \(/g sso-shop-med.txt

Answer 5

在UNIX中使用Perl，可以解决这个问题。

use strict;
use warnings;
while(<>){
print if(s/\((values)\)/\ $1 \/);
}

输出：

insert into brs.user_shops (user_name, shop_id, is_active, created_date, created_by, last_updated_date, last_updated_by) values ('204026601',18, TRUE, current_date,'502675409',current_date,'502675409'); 
insert into brs.user_shops (user_name, shop_id, is_active, created_date, created_by, last_updated_date, last_updated_by) values ('502689031',18, TRUE, current_date,'502675409',current_date,'502675409'); 
insert into brs.user_shops (user_name, shop_id, is_active, created_date, created_by, last_updated_date, last_updated_by) values ('502683504',18, TRUE, current_date,'502675409',current_date,'502675409');
