这在 sed 中可行吗？
我想将以 [ 开始并以 ] 结束的元组中的 , 替换为 |
"platform": "iPhone","report_attrs": {"SKU": "XYZ123","Unit Price": "32.25","Qty": "3"},"screen_flow":["Main","Login"]
"platform": "android","report_attrs": {"SKU": "XYZ123","Unit Price": "32.25","Qty": "3"}
输出:
"platform": "iPhone","report_attrs": {"SKU": "XYZ123","Unit Price": "32.25","Qty": "3"},"screen_flow":["Main"|"Login"]
"platform": "android","report_attrs": {"SKU": "XYZ123","Unit Price": "32.25","Qty": "3"}
如果不可能，我们将不胜感激任何其他解决方案。
谢谢。
最佳答案
下面的 perl 代码将用 | 符号替换 [] 大括号内的所有 ,。
$ perl -pe 's/,(?=[^\[\]]*\])/|/g' file
"platform": "iPhone","report_attrs": {"SKU": "XYZ123","Unit Price": "32.25","Qty": "3"},"screen_flow":["Main"|"Login"]
"platform": "android","report_attrs": {"SKU": "XYZ123","Unit Price": "32.25","Qty": "3"}
要保存所做的更改，
perl -i -pe 's/,(?=[^\[\]]*\])/|/g' file
