Coming to learn better the differences between #grep #awk and #sed.

Learning that my frustration with grep is that I misunderstood what its (at least base and intended) function is, and I've been trying to make it do things that are much more suited to things like sed and awk.

#grep -rsn "pattern" . command, along with context flags like -A (After) and -B (Before), recursively searches directories (-r), suppresses error messages (-s), and displays line numbers (-n). It is highly effective for finding text patterns across multiple files while ignoring file read errors
#cURL flags are used to modify HTTP requests for debugging, authentication, or automation, with -I showing headers only, -i showing headers + body, and -H adding custom headers. The fss typically refers to a combination of curl -fsSL for silent, fail-fast, redirect-following downloads.
