code snippet seem never be executed

In swbd/s5c/local/swbd1_train_lms.sh, lines from 49 to 51 seem would never be executed.

I do not know if there is any problem here.

Why do you think they are never executed? To me it seems standard code that checks if those two files exist.

[yzmyyff]

for f in "$text" "$lexicon"; do 
  [ ! -f $x ] && echo "$0: No such file $f" && exit 1;  # $x is a missing variable, or it should be $f?
done

Yes, there is a bug. Maybe you can make a PR to fix it?

Thanks, I will.
