    switch between user account and sudo/root ubuntu 12


    I have abash script in which in midle
    I have to change the etc/hosts and
    /etc//product/conf files.

    How do i switch for a time the context
    of the bash to act as sudo.
    Looks likejust prefixing the commands with
    sudo command goes in a subshell

    and never returns.
    Thank you

    perhaps sudo is not set up right. you should be able to include the command (and possibly the username, if not root) on the command line, after sudo, e.g.:

    Code:
    sudo whoami
    that should return "root".

    you can list acceptable commands with:

    Code:
    sudo -l
    (that is a lower case L)

    if you are still having problems, inspect the sudo config file, /etc/sudoers and also any optional config files in /etc/sudoers.d/.

    Off-Topic:
    For reproduceable configuration file handling, you might want to have a look at augeas, which can be used as-is or from e.g. puppet
    You must always face the curtain with a bow.

    Thank you
    -l worked
    ----------------------------------------------------------
    #!/bin/bash

    echo "#added as $(whoami)" >> ~/hosts # as user
    su `whoami` -l "echo "#added" >> /etc/hosts" # in /etc/ as 'root'
    echo "#added as $(whoami)" >> /etc/hosts # as user again

    cat /etc/hosts
    cat ~/hosts

    ls -l ho*
