Dear Allen:
I think you only want to easily find the information which is important for you. I suggest you can do this:
substitute
print “—the something you want to output”
for
print “the something you want to output”
And then, you can use the command “grep” of linux to deal with log.lammps file. For example: grep “^-” log.lammps > result
I hope it will be useful for you.
Yours
