Thank you, Matt, for your valuable advice! I did try using ';' to issue three
commands at once and it works!
However, I have more problems with issuing ClearCase commands, which is what
I am really doing.
Under telnet, I could issue commands one by one, just as typing at the
command prompt. Now I tried to use ';' manually typing two commands at once
on my Solaris command line, such as
ct setview viewName; cd dir_in_clearcase
(ct = cleartool) The second command will not be executed, since the command
prompt changes after the first command. --- I think that it was because
there was a long delay after the first command. (any way out?)
When I used exec_command() to do this in Python, even the first command was
not recognized (error: bad phone number. I used 'man ct' and found that ct
dials a phone number). Even if 'ct' was recognized, the second command would
not be executed. And it is useless to do it in the next exec_command()
function. (Without the first command, one can not cd into a directory in
ClearCase.)
Do you think that paramiko can replace telnet in my application? Thanks.
