Ok i get the work done by paying $5 on vworker by finding a linux administrator.

Seems like Linuxquestions users doesn't trust other users.

It's not that: it is your machine so nobody here at LQ should be burdened with the responsibility of (or lured into) solving your problems for you.

I'm glad that you were able to solve your issue. You bear the responsibility of resolving issues not LQ members. So your observations that LQ users do not trust other users has no merit. Fellow LQ members did provide useful information but you did not wish to follow directions nor provide sufficient information(s) to aid in resolving the issue(s).

I do suggest that you re-read LQ Rules, especially;

I am out of here, i am not going to use linuxquestion in future anymore, just delete my account and keep this thread active if you say linuxquestions users are good and helpful to all and thanks for quick replying atleast.

LQ is VERY helpful if you know how to ask and look for help.
If you need/want help from some user, then use PM to contact, don't post your intentions and details public.

I was at work and I couldn't reply, but reading this now, how this post overgrown its meaning, I'm glad I didn't.
khanahmedabbas You were given the recommended solutions, but obviously you didn't solve it.
I'm sorry, but you will need to get into some Google and manuals/tutorials about it.

Regards.

To execute any linux command in background we use nohup as follows:

1
$ nohup SOME_COMMAND &
But the problem with scp command is that it prompts for the password (if password authentication is used). So to make scp execute as a background process do this:

1
$ nohup scp file_to_copy user@server:/path/to/copy/the/file > nohup.out 2>&1
Then press ctrl + z which will temporarily suspend the command, then enter the command:

1
$ bg
This will start executing the command in backgroud

some points.

1. first before you can automate the scp of files you first must automate the permissions. do that by reading the links in my signature about ssh keys.

2. as you are running putty, this might not work well for you as i dont have the slightest clue how to get MS windows OS to create a proper ssh key.

3. the steps above are very clear. screen works in putty, if and only if screen is configured on the computer you are remotting into on the other end.

4. provided that screen works, you would perform the following:

Code:

Last login: Tue Dec 17 16:41:25 on ttys000
user-imac:~ ssma$ ssh user@server 
Last login: Tue Dec 17 16:43:37 2013 from imac
[user@server ~]$ screen

this should clear your current screen
now issue your scp command, and if you are unable to create ssh keys, then type in the password. you can now type: CTRL + D to detach and exit out of putty. that is a capitol D, not a lower case. like most commands in Linux, screen is case sensitive.
