i got :
$ ./ssh_exec_ls.rb
exec: 4: cd: not found


if, by command line, i log into the device :
$ ./ssh_connect.zsh open
Enter passphrase for /Users/yt/.ssh/id_dsa: 
Identity added: /Users/yt/.ssh/id_dsa (/Users/yt/.ssh/id_dsa)

# which cd
# 

notice "which cd" returns nothing, this is a builtin shell command.

for example on MacOS X :
$ which cd
cd: shell built-in command

i should mention the remote device is a handheld phone running linux
Kernel 2.4.x (QTopia over OMAP 730 from TI)


also, I've a lot of "SCP did not finish successfully" not repeatable.
those scp errors are only reported when using ruby (net/ssh + net/scp)
but not when using my zsh script.
