Search a multi-line shell command output and execute logic based on result
The following is a multi-line shell command example:
What I would like to accomplish here is to use the above multi-lines returned by cargo build command. Search all multi-lines for error[] substrings and store the count in a variable so the result can be used to handle another case logic.
Ideally, I want to accomplish something along the following code block:
I realize the above block is broken. This is just what I have to work with for the moment. The only difference in my example is that I need to search for error and brackets strings and not the error string by itself. i.e. error[E0412] the top cargo build command should return a count of 2
A bit of an unrelated question, the snippet mentioned by Scrutinizer works when calling cargo build. If I use a hot-reload tool such as cargo-watch as my initial command, it does not work. I was reading the documents for cargo-watch and it seems to be built on top of watchexec, not sure if that blocks I/O somehow? Does anyone know how I can get the grep command to work with cargo watch? What is stopping it from functioning as intended?
