How to write a bash script that counts the number of commands executed?

Question

linux

When closing the console, it is necessary to display a message with the number of commands executed for the current session, the history command does not work in a bash script, what other options are there?

Answer 1

Make a variable and plus after each command.

var=$((var+1))
((var=var+1))
((var+=1))
((var++))
let "var=var+1"
let "var+=1"
let "var++"

Answer 2

works, google "getting data from command output" :)
but it's better to read in ~/.bash_history script directly.
