I currently have an assignment in which I must use egrep to extract objects of a certain type from a .json file. Normally, using grep for this would not be much of a problem, as I can use recursive capturing; however, this requires the -P option, which this assignment forbids. The only options allowed to use with grep for this assignment are -o and -E. I also cannot use other tools such as jq. With this in mind, how could I capture .json objects that may have an arbitrary number of objects nested within them, which can recursively have objects nested with them, etc.? I might even use "-b" to count how many opening and closing brackets have been encountered, but this is forbidden as well. I cannot see any means of parsing a json file using only egrep, please explain how this can be done.
