Is there a switch or a tool for that? It would be usefull to know how long emerge gone work.

You can measure the time that a command (like emerge) takes to run by using the "time" command.

You might also be interested in genlop (which you need to install separately). I don't think you will have any problem finding usage examples around the net and in this very forum.

Thank's. Genlop can be good to know the time after emerge finish to work. I am looking for something to estimate it before it start to compile.

genlop also works for current emerges, but needs a completed emerge to give you an estimate.

If you have not yet built the package, then estimating the time requirement is difficult. The time requirement depends on what features you enabled and how much CPU/memory/disk are available to the build process.

See genlop's -q flag. It'll only work if your CPU/package combination is in the database though.

genlop also has a -pretend option. Just pipe an emerge to genlop -p. Just like others have said, genlop needs previously installed packages to be accurate.

Again, genlop. There's nothing else. The more you use it the better the estimation should be. Still an estimation, though.
