I’ve been in some situations where I’d like to add timestamp to pings. There could be loads of reasons as to why you’d like to do this, but I used it to check if there where specific times of the day that had higher latency on my internet-connection at home.
You ever wanted to find something within loads of files? And you’d like the matching lines to be printed? And with line-numbers? What if you’d like the X lines above/below matching lines to be printed? No problem.
