If I create a file containing


and run it, I get no output. Running it manually in a terminal or sourceing the script file does produce output.

Why does history not work from a file?

The second command does "work", but the history is not enabled for non-interactive shells which is why it returns nothing in your script.

$ cat nohistory.sh
set -o | grep history


$ ./nohistory.sh
history         off


$ cat history.sh
set -o history
set -o | grep history


$ ./history.sh
history         on
    1  set -o | grep history
    2  history
