[analog-help] Re: excluding a timespan in the middle of FROM, TO

[janet ward]

Thank you Klaus Johannes Rusch for your reply. As I said, I am a 
programming/coding klutz.

So your reply, which is no doubt very helpful if I could understand it,

<The only solution I can think of without modifying the code is 
<filtering the requests before analog processes the log file, either by 
<reading from stdin and filtering using grep, or by using a filter as a 
<preprocessor.

<cat log | grep -v -f file-with-date-time-patterns-to-exclude | analog <...

means nothing much to me.

Where is stdin, how do I read from it and how do I do a filter?
How would I use a filter (what would that look like?) "as a preprocessor"?

I'm afraid that I am 'drowning' in this strange talk and need a very 
large and buoyant life-jacket to help me keep afloat and navigate 
through this verbage. Sigh.

Sorry.
