sudo in bash script: Doesn't always wait for password

Question

I have a simple bash script like this:

#!/usr/bin/env bash

sudo ./some_other_script_01
sudo ./some_other_script_02

When I execute this script, I always see the password prompt, as usual:

[sudo] password for user: 

However sometimes, inexplicably, before I have typed my password, ./some_other_script_01 starts getting executed (presumably without root permissions). This happens even though it did prompt me for a password (which I didn't yet provide).

Currently, when this happens, I have to kill the scripts and start again (so that they get executed with root privileges).

Answer 1

Sudo once is enough, just start the wrapper.sh with sudo. Check if you have root permission in the script no more sudo calls needed.

sudo ./wrapper.sh

wrapper.sh:

#!/usr/bin/env bash

if [ "$EUID" -ne 0 ]
  then echo "Please run as root"
  exit
fi

./some_other_script_01
./some_other_script_02
