I'm not familiar with cleartool - could it be that the first command you
are using is invoking an application that is not returning to the command
line?, for example, if you were telnetted in and doing the same would you
literally type

$>ct setview viewName
$>cd /some/where

or does the session look more like

$>ct setview viewName
_new_ct_prompt> exit
$>cd /some/where

If that is the case, it mightbe possible to direct ct to get it's input
from a file

ct setview viewName < exitfile; cd /some/where

and exitfile has the word 'exit' in it.

just an idea though. may not work.

I'm a bit confused here. - Do you have an application called 'ct' (from
previous paragraph, it appears you do. But if you are issuing 'ct' via
python and getting 'bad phone number'??)  Can you explain the bigger
picture a bit more, and what ClearCase is?

Why do you say 'Even if ct was recognized, the second command would not be
executed' - if ct was recognised and returns to the command line prompt I
would fully expect the second command to execute.


> Do you think that paramiko can replace telnet in my application? Thanks.

I think it would be taking it a bit far if you are just trying to automate
something unless you really have to run on a remote machine. Then either
telnet or paramiko should work. You could also maybe look at using python
to invoke rsh/rexec processes if telnet was suitable in the first place.
