I have a script which contains
while true sudo mycmd sleep 10000 [ ... ] ; break end
when I run the script in bash, I will have to provide my password once in 10000 seconds after finishing running the previous instance of
yes | somecommandcan repeatedly provide
yesas stdin input to
somecommand, as answers to repeated questions of “Yes or No”. I wonder how I can provide my password repeatedly to the script?
The password can be piped into the
sudo command but this is not secure in any way at all and should be avoided if possible.
echo 'hunter2' | sudo -S mycmd
A better method would be to just run the entire script with
sudo and only require the password once.
sudo password can also be avoided entirely but is also not recommended for security reason. This can be done by updating the
/etc/sudoers file with the
visudo command and including a line such as this for all users in the
%wheel ALL=(ALL) NOPASSWD: ALL
To disable it only for a single user switch
%wheel with the users username.
