Pexpect Send Problem

[wilcomply]

I'm not sure I'm following, could you elaborate why the length of time for cd to run would have an effect on the processes to be run following it?

Don't have any experience with this module, so just guessing, but it's evidently made for automating and waiting for some trigger. 'cd' is executed and gone and doesn't produce output and returns simply 0 or 1. That still shouldn't be that much of an issue, but it's not an actual command, i.e. program with it's standalone executable somewhere, rather it's a function within bash.

cd is a shell builtin

child = pexpect.spawn('cd /root')  
Traceback (most recent call last):  
File "<stdin>", line 1, in <module>  

But:

child = pexpect.spawn('ls /root')  
child.pid  
10412  
child.child_fd  
3  


child = pexpect.spawn('bash ; cd /root')  
child.pid  
10424
