Re^3: how to populate array with last 20 lines of file

Yeah .. not surprising, since you tail the file once, and then stop.

Why not read it, sleep for a minute, then read it again, as your original script tried to do?

in original script, the purpose of sleep() is to compare if the size of file changes. And Tail still does not solve my problem of only populating an array with last few lines of file, so does Readbackwards.	[reply]
