I don't think this answers what the OP is trying to do. The idea is for sequential commands to each consume a portion of the same pipe stream, each picking up exactly where the previous one left off.

What I'm trying to achieve is a bit different of your script. I would like, for example, cmd1 processing the first 10 lines, cmd2 processing the next 15 lines, and so on. Cmd1, cmd2, etc are bash functions, and these functions decide the number of lines to be processed according to the input.

@arnaldocan Ok, I think rightly understand the need, look the sample script and last command sample.

I think the fourth example solves the problem. Is there any way to avoid using "read" because of its speed limitations on large files?

You may use mapfile -n $numLines arraOfLines
