linux - LINUX 中的替换模式

Question

2.txt

"platform": "iPhone","report_attrs": {"SKU": "XYZ123","Unit Price": "32.25","Qty": "3"}

"platform": "android","report_attrs": {"SKU": "XYZ123","Unit Price": "32.25","Qty": "3"}

我想将 ,*:*{ 替换为 ,

o/p:

"platform": "iPhone","SKU": "XYZ123","Unit Price": "32.25","Qty": "3"}

"platform": "android","SKU": "XYZ123","Unit Price": "32.25","Qty": "3"}

这是我尝试过的:

sed s/,*:*{/,/g 2.txt

Answer 1

sed 正则表达式中的

,* 表示匹配零次或多次出现的 , ，而 :* 表示匹配零次或多次出现的 : 符号。

通过 sed，

$ sed 's/,[^:]*:[^{]*{/,/' file

"platform": "iPhone","SKU": "XYZ123","Unit Price": "32.25","Qty": "3"}

"platform": "android","SKU": "XYZ123","Unit Price": "32.25","Qty": "3"}

或者

$ sed 's/,[^{]*{/,/' file

"platform": "iPhone","SKU": "XYZ123","Unit Price": "32.25","Qty": "3"}

"platform": "android","SKU": "XYZ123","Unit Price": "32.25","Qty": "3"}
