Does anyone know how to access and use the .profile in UNIX while using
NET::SSH in Ruby?

Thanks for the help

I believe we just need to load it into the session/channel so that we
can use access/use command associated with the .profile

We are trying to run a command through Ruby but it seems that we need
certain environmental properties set (e.g. .profile) in order to do
this. If we log onto the server through Putty this command works just
fine.

How to you mean? By updating it, parsing it from the file itself, or by
using finger, or?

If the only way to get this to work is to set the environment/variables
or emulate them somehow in the Ruby script, that is what we will need to
do. Any idea as how to do this?

Sorry, I got you. I read the post too quickly and for some reason I
thought you said .plan (I should have known that sounded strange).
Indeed, the .profile is only set to work with shell, in the shell env,
which is why CGI, web server APIs/modules and rails don't read it. Did
you need to set any environments or did you want to emulate or somehow
use the shell vars naturally (assuming you can trust the
user's .profile)?

you need to invoke a login shell on the remote host, then
your .profile will be sourced.

probably there is some option to specify the remote shell for
Net::SSH, specify something like

'/bin/bash --login'

alternatively wrap your commands in something that does this for you
like

cfp:~ > cat `which bashenv`
#!/bin/bash --login
exec "$@"


and then invoke commands like 'bashenv something.exe'

You can 'source' the .profile in your ssh session doing a:
cmd=". /home/user/.profile"

note the space after the dot.

Read the docs about the intended use and behavior of ~/.profile or
~/.login or ~/.bash_login compared to ~/.bashrc

It's probably in the INVOCATION section of the manual for your shell.

If your server is running OpenSSH, you can also use ~/.ssh/environment.

See sshd(8) for details, under the LOGIN PROCESS section:
