当然,如果您真的想打动R2D2,也可以避免输入密码提示。准备您的用户帐户,使其看起来像这样:
you@yourhost:~$
you@yourhost:~$ cat /home/you/.bash_login;
# ASK_PASS service for you «begins»
export SUDO_ASKPASS="/home/you/.ssh/.supwd.sh";
# ASK_PASS service for you «ends»
you@yourhost:~$
you@yourhost:~$
you@yourhost:~$ cat /home/you/.ssh/.supwd.sh;
#!/bin/sh
echo '(Your sudoer password here)';
you@yourhost:~$
you@yourhost:~$
you@yourhost:~$ ls -l .ssh/.supwd.sh
-rwx------ 1 you you 35 Mar 31 10:28 .ssh/.supwd.sh
you@yourhost:~$
you@yourhost:~$
you@yourhost:~$ cat ./tmp.sh
#!/bin/sh
. /home/you/.bash_login; # 'source' bash_login to declare the ask_pass script
sudo -A add-apt-repository ppa:(Your ppa here) -y;
# The flag '-A' lets you add the repo without sudo demanding your password.
#
you@yourhost:~$
-y
在命令末尾添加即可add-apt-repository -y ...
。
