Help with logging into machines

[pcdj]

When I bring up the command window
[testf@mach6-test1 testf]$
at this prompt I put ssh testf@mach-test1

Then this comes up testf@mach-test1's password:

after putting the password in and hitting return

this comes up [testf@mach-test1 testf]$

at this prompt I put cd /sample

at the last prompt [testf@mach-test1 sample]$

I put ./start

and when I want to stop at the prompt I put ./stop

I need to do all of this simultaneous for

ssh testf@mach-test1 shh testf@mach-test2 ssh testf@mach-test3 enter password cd /sample then ./start and/or ./stop

Thanks
