Hi,

I just noticed today that many users do not know about a new tiny feature in CPLEX 12.9:

We can now export the cplex log when calling cplex with command line oplrun.

For example, let me use volsay.mod in CPLEX examples:

oplrun -l log.txt volsay.mod

will run volsay.mod and build log.txt

Tried aggregator 1 time.
LP Presolve eliminated 1 rows and 0 columns.
Reduced LP has 2 rows, 2 columns, and 4 nonzeros.
Presolve time = 0,02 sec. (0,00 ticks)

Iteration log . . .
Iteration:     1   Dual infeasibility =             2,500000
Iteration:     3   Dual objective     =          2300,000000

regards
