bash calc

ok if i write 1+1 in prompz i get error message....is possible to use "calculator" in bash (like in python shell)

expr 1 + 1

bash does not have builtin math functions like python or perl

You could potentially use a sort of built-in Bash utility:

Code:

---

echo $[1 + 1]

---

$[...] syntax means "do the math in here", and the echo prints out the result.

Also, you can install commandline calculators. I personally am fond of Qalculate!: there is a CLI version that you get when you install the GUI version.

anyway i dont have to make any calculations (i was just curious);

thanks
