Sorry fewi, maybe after some time I will start to understand, but for the time being to me this is the same as a Chinese just learned the first English trying to explain me how to make bread....
"remove" I can understand, I use it in given example as "rem"
But the [find] part...
Wiki Manual: find :
:find <arg> <arg> <start> return position of substring or array element
To me it is all acadabra.
<arg> probably means I have to fill in an argument. But which in this case? And do I use the "<" and ">" parameters?
"<start>"? What does this mean? To start what? What to fill in here? Why do I need that? I already start a command by hitting the enter button?
"return position of substring or array element" ???? I stand better change to make that bread.
From the given Wik manual example I presume I have to fill in some value in-between the [ ] hooks embedded with " " and have to start with the word "find". But what then? And what to put in-between these " "?
Something like "all"???
All I want is to erase all present unknown numbers of my /system logging output.
I have to do this on 250+ units so it would be easy to catch it in a script I can just past into each units terminal to have it done.
In plain words my command would read:
"erase all lines in /system logging print output and set new one(s)"
How to set the new ones is clear to me, but how to remove the old ones.... (in a smart way...!)
