Can you sudo with input whiptail?

I want to ask your sudo password with whiptail password and then use it to run sudo script.sh this is possible?

I have tried this sudo command with the whiptail input for password

sudo -S <<< $psw script.sh

echo $ psw | sudo -S

Full Code

#!/bin/bash

#Password Input
    psw=$(whiptail --title "Test Password Box" --passwordbox "Enter your password and choose Ok to continue." 10 60 3>&1 1>&2 2>&3)
    #Password If
    exitstatus=$?
    if [ $exitstatus = 0 ]; then
        sudo -S <<< $psw script.sh
    else
        #Password If cancel
        whiptail --title "Cancel" --msgbox "Operation Cancel" 10 60
    fi
Solution

  • A quick check shows the script should work (works for me). Your script is calling sudo separately from whiptail, so the two are not interfering with each other's use of the terminal.

    The script should begin with

    #!/bin/bash

    because it uses the here-string

    <<< $psw
