How to set a timeout in COIN-OR Cbc via the command line tool?

I'm using COIN-OR Cbc via its cbc command line tool and need to abort some computations if they take too long.

I'm aware that I could write a controlling process around cbc to kill it after the timeout expires. I'm also aware that I could use cbc as C++ library. Both seem so be quite cumbersome, I'm looking for a simpler, direct solution.

Is this possible directly via the cbc command line tool?

If not, is there a simple way using cbc as C++ library? (read an *.lp file, apply timeout, create *.soln file)

Yes. Use the -sec command-line option. The full command line would be:

cbc -sec 10 -import inputfile.lp -solve

This is equivalent to running an interactive session by typing only cbc on the command line, then entering the following commands:

sec 10
import inputfile.lp
solve
