[SOLVED] Sed + replacing the content after specific syntax

Issue

we try to replace the content of the third field that comes after group word ,

the following line in file is always with the same syntax except third field that change

"groups": [{"group": "string”}],

The third field contains any characters of combination of A-Z , a-z , numbers , ( _ - . )

The third field is always in double quotes

Example

"groups": [{"group": "MOVIES.ARE.GOOD”}],

"groups": [{"group": "no_one.ok”}],

"groups": [{"group": "evry_one.lol”}],

"groups": [{"group": "NO_VALUES_ARE-GOOD”}],

"groups": [{"group": "___scripts”}],

etc

I try with the following sed , but without success

var=my.word__that.I.need.to.replace
sed  -i "s/\(group\": \"\)[*]*/\1$var/"  file

Solution

Assuming:

• all quotes are ". See the comment from @Gordon above.
• you want to replace the 3rd field in each line.
• the replacement value is stored in a variable.

• I tested my command on this file content (filename data.txt):

  "groups": [{"group": "MOVIES.ARE.GOOD”}],  
  
  "groups": [{"group": "no_one.ok”}],
  
  "groups": [{"group": "evry_one.lol”}],
  
  "groups": [{"group": "NO_VALUES_ARE-GOOD”}],
  
  "groups": [{"group": "___scripts”}],
  

This works for me:

newword=TATA
sed -i "s/\(group\": \"\).*/\1$newword\"\}\],/"  data.txt

Basically, everything that follows group": " is replaced by TATA"}],

---

My result file now contains:

"groups": [{"group": "TATA"}],

"groups": [{"group": "TATA"}],

"groups": [{"group": "TATA"}],

"groups": [{"group": "TATA"}],

"groups": [{"group": "TATA"}],
