comment When running Mathematica from a Linux terminal, how can I prevent a script from terminating upon logout?
I'd rather do math -script test.txt & disown, where & puts the script into background, and disown detaches it from the current terminal - instead of all that manual magic with redirections and nohup, which would also create a nohup.out file.

@DumpsterDoofus yes, it's a Hamiltonian matrix. What similarity transform do you apply?

Are you sure your implementation gives the correct results?

@ybeltukov Wow, you're right. This could make an answer.

@ybeltukov but shouldn't zeroing it clear all the history already present?

Oh, indeed, using FullSimplify instead of Reduce gives True without warnings. Still, it doesn't reveal $(1)$ without need to put it into expression.
