So, what JSON do you have, what part do you want to extract and how does your current code fail? Please edit your post and show the Minimal, Complete, and Verifiable example.

Got the solution,
I am getting following JSON response from curl and storing in variable :
CURL_OUTPUT='{ "url": "protocol://xyz.net/9999" , "other_key": "other_value" }'
Question :I want to read the url key value and extract the id from that url:
Answer : _ID=$(echo $CURL_OUTPUT |awk '{print $2}' FS='url":' |awk '{print $1}' FS=',' | awk '{print $2}' FS='"'|awk '{print $4}' FS='/')

That is a bit of overkill -- 4 calls toawkand 4 calls toprintfwithin a command substitution -- that's a minimum of 9-subshells spawned plus 4 pipes just to parse'9999'. Better to make a single call togrepassign the result to a temporary variable and then use the shell parameter expansion to delete up to the last'/', e.g.tmp=$(echo "$CURL_OUTPUT" | grep -o 'protocol[^", ]*'); _ID="${tmp##*/}"
