I want to rewrite the shell script to python script so I have had
changed the "ssh-agent -s" to 'ssh-agent cmd' in python script for the
consistence on windows.
There are two inputs in the two commands. I tried code use
communicate method and write method and got errors:
Cannot send input after starting communication
ValueError: write to closed file
I found the communicate method just run one times.
The manual input process is as follows:
1. run cmd.exe
2. input 'ssh-agent cmd' press return, the window display a new prompt.
3. input 'ssh-add id_rsa' and press return, it will ask the id_rsa
password. After input correctly password, it will display 'Identity
added: id_rsa (id_rsa)' and a new prompt.
p = subprocess.Popen('cmd', stdin = subprocess.PIPE, stdout =
subprocess.PIPE, stderr = subprocess.PIPE, shell = True,
universal_newlines = True)
outinfo, errinfo = p.communicate('ssh-agent cmd\n')
print('outinfo is \n %s' % stdoutinfo)
print('errinfo is \n %s' % stderrinfo)
After a lot of searching and learning I still do not know how to code
it, I realy need help.
Thanks a lot.
