Re^3: How to read from shell command and terminate it afterwards?

True. He said:

This command outputs to stdout [a] few lines of information, which I am looking for ...

But mostly it suggests he knows how many.

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

"Science is about questioning the status quo. Questioning authority".

In the absence of evidence, opinion is indistinguishable from prejudice.

No, it does not suggest he knows (exactly) how many. In fact, the OP was pretty clear that the length of the output depends on external factors. He may know exactly how many lines he needs to read, so I'm not saying that your solution isn't viable. I'm just answering your question.	[reply]

What if this small number varies :) ? It can be three, two, five, depending on the circumstances? Then relying on that number can lead to data loss or blocking read.	[reply]
