Hi all:<br>
<blockquote>i have some doubts in doing python programming<br>
<br>
i wanted to execute a command "su -c 'fdisk -l'",and it needed a
password<br>
so i wanted to write a python script to get this done.<br>
<br>
i knew 'pexpect' would work fine,but i had to set a certain
timeout to take care of the real delay time which i probably
didn't know<br>
<br>
i tried to use 'subprocess' to do this,however,it did not work
well,and came the problem<br>
<br>
i use Popen to execute "su -c 'fdisk -l'" in sub process,and
assigned subprocess.PIPE to stdin,stdout<br>
i tried to enter password by doing "stdin.write("password"+"\n")"
and i expected i could get the output of "fdisk -l" by doing
"stdout.read()"<br>
it didn't work.<br>
<br>
will somebody tell me what is going on with that?<br>
i'll appreciate i can learn from you<br>
<br>
Dou<br>
