查找和AWK命令替换

我有一个名为sso_med.txt像查找和AWK命令替换

197: insert into brs.user_components (user_name, component_id, created_date, created_by, last_updated_date,last_updated_by) values ('502683504',15,current_date, '502264160', current_date, '502264160'); 
198: insert into brs.user_components (user_name, component_id, created_date, created_by, last_updated_date,last_updated_by) values ('502683504',16,current_date, '502264160', current_date, '502264160'); 
199: insert into brs.user_components (user_name, component_id, created_date, created_by, last_updated_date,last_updated_by) values ('502689031',15,current_date, '502264160', current_date, '502264160');

文件，但我想让它像

insert into brs.user_components (user_name, component_id, created_date, created_by, last_updated_date,last_updated_by) values ('502683504',15,current_date, '502264160', current_date, '502264160'); 
insert into brs.user_components (user_name, component_id, created_date, created_by, last_updated_date,last_updated_by) values ('502683504',16,current_date, '502264160', current_date, '502264160'); 
insert into brs.user_components (user_name, component_id, created_date, created_by, last_updated_date,last_updated_by) values ('502689031',15,current_date, '502264160', current_date, '502264160');

我想awk命令

awk '{gsub(/^\d+:\s/,""); print}' sso_med.txt

但它不工作。任何想法我正在做错在正则表达式

'\ d'无法识别。用'[0-9]替换它' –

尝试

awk '{gsub(/^[0-9]+: /,"")}1' file

它工作:) thnx很多 – sromit

Downvoted缺乏解释。请注意，与你的表情相比，提问者的表情是否正确/错误。 – SeldomNeedy

尝试也sed的版本：

sed 's/^[0-9]*: //' Input_file

从0到9，然后替换起始位：空间与NULL并打印其余部分。

为了避免该串中的其他地方去除相似的模式，使用sub，这只是替换模式的第一个实例：

# explanation of regex: "^"=line starts with pattern, "[0-9]+"=multiple numbers, ": "=colon and single space 
awk '{sub(/^[0-9]+: /, "", $0); print $0}'

实施例：

$ echo '197: insert into brs.user_components (user_name, component_id, created_date, created_by, last_updated_date,last_updated_by) values ('502683504',15,current_date, '502264160', current_date, '502264160');' | awk '{sub(/^[0-9]+: /, "", $0); print $0}'

结果：

insert into brs.user_components (user_name, component_id, created_date, created_by, last_updated_date,last_updated_by) values (502683504,15,current_date, 502264160, current_date, 502264160);
