ATTN: Programmers, Need HELP with shell script...

[OneQuickSix]

Im trying to write a script which works as follows:

machine A (where my script is)
machine B (the machine where I'm trying to SSH)

while script runs on A, I'm trying to ssh B, and collect data from a file on B and copy it to a file on A.

---------------------------------------------

I've tried backgrounding the SSH but this alone is not working. :(
Once i ssh, I'm considering entering machine B. (the script hangs at new host B)

Any ideas on how to code this?

Thanks in advance for any input!

ssh really isnt scriptable. you might be able to do something stupid like:

ssh me@remotehost cat my_file_on_remote_host > /tmp/oh_look_my_file_from_remote_host

however, it looks like you just want to bring a file over from host b, so use scp "ssh cp" instead.

scp me@remotehost:my_file_there my_file_here

do need something more complicated? perhaps grabbing the last few lines of a logfile?

ssh me@remotehost tail -10 logfile_on_remotehost > last_10_lines_of_logfile_from_remotehost

[edit: you could probably script ssh with expect if you really really needed some sort of programmatic control over ssh.]

Chas,

Thanks for the ideas.

I figured out how to do copy files over using ssh:

ssh {remote host ip} cat {file name on remote host} >> {file name on host}

This works fine. But I am now trying to figure out how to execute a script on the remote host (B) from the host machine (A). Basically, I want the main script to envoke the other script (located on remote host).

I tried the same type of code as above to do this, but it doesn't work since I am not using a system command (like "cat" above)

Any other suggestions?

Thanks again for all your help.
