I want to delete all "tags":[xxxxx] array in a JSON text string e.g. "aaa":"bbb","tags":[abcdefg],"ccc":"ddd"

I used grep to get the regular expression right

to escape the [ character in grep command, why two \ is required?

then I tried to use sed to replace "tags":[abcdefg]

sed s/\"tags\":\\[.*\]//g

it does not work.

Can someone give suggestion?

You have to format your code, either on a separate line with four spaces indentation or with backticks (`\``). It's impossible to tell how many backslashes you meant to put there. Also, you probably want to use a JSON parser such as jq, not grep/sed/awk. – Benjamin W. Aug 29 '17 at 03:55
post your input json – RomanPerekhrest Aug 29 '17 at 04:54
Use `sed 's/"tags":\\\[.*]//g` – Wiktor Stribiżew Aug 29 '17 at 06:39
Sorry, first time stackoverflow user. I did notice weird display of / character in preview when I write this question yesterday. I just edited it – ecsk Aug 30 '17 at 01:02
Wiktor, thanks. the 3 backslashes works ! – ecsk Aug 30 '17 at 01:05
