scp transfers file successfully into host machine but file won't show up

Question

I am trying to transfer a file from my local machine to a remote machine.

When I use scp without -v option it gives only following output:

.--. or '\033[0;1;33;93m.-\033[0;1;32;92m-.\033[0m'

When I try scp with -v option I get following output, seems files transferred succesfully:

--

$ scp -v file.sh  user@IP:/home/user/foo

debug1: channel 0: new [client-session]
debug1: Requesting no-more-sessions@openssh.com

Please see sshd_config file here. Please note that I can ssh into the remote machine. Also ssh user@IP pwd returns /home/user.

[Q] scp successfully transfers file but it does not show up on the remote machine. What might be the reason for this and how could I solve it?

How do you know the file doesn't show up on the remote machine? — Andrew Henle, May 01 '18 at 09:50
I do ls on the folder path at remote machine, it returns nothing. @Andrew Henle — alper, May 01 '18 at 09:51
Do you have access to the sshd configuration files on the remote machine? If so, you should post the contents of those files here. — Andrew Henle, May 01 '18 at 09:54
Yes I have access. sshd_config file: https://gist.github.com/avatar-lavventura/7d5b20bb8dde23325e0b32a678e97dfc — alper, May 01 '18 at 09:58
Is the source file really called file.sh - or does its name use characters from a different locale? — steeldriver, May 01 '18 at 12:42
I just used a dummy name. I have also tried file having helloworld.txt but didn't help. @steeldriver — alper, May 01 '18 at 12:51
From the remote machine, what does ls -l /home/user/foo show? — Andrew Henle, May 01 '18 at 13:48
I just did ls /home/user/fooat the remote host. Yes directory called foo exists @roaima — alper, May 01 '18 at 15:52

Thanks adding # If not running interactively, don't do anything [[ $- == *i* ]] || return on top of my .bashrc file solved the problem! @ Anthony Geoghegan — alper, May 11 '18 at 17:33

Make sure you don't have startup scripts in your shell that echo data to the terminal. This might be in .bashrc or .profile

When scp connects to the remote host, it expects to see the SSH server headers followed by an opened stdin stream.

If your .profile on the remote host echoes any output, it causes scp to fail silently. If this is the case, you might want to remove this or put a guard condition to ensure that nothing gets printed in the absence of a controlling tty device. See tty command for that.

I have a startup script on my .bashrc which I to keep it. I am not sure it may be the reason to cause this problem. @rohit. – alper May 06 '18 at 11:34

this is most probably a reason, please make sure that you have something like # If not running interactively, don't do anything case $- in *i*) ;; *) return;; esac
in beginning of your bashrc and you not run external commands in .profile
– zb' May 06 '18 at 13:34
That's an interesting snippet @zb'. I've always used [[ "$(tty)" != "not a tty" ]] && return – rohit May 07 '18 at 05:12
@rohit it is from my default bashrc, ubuntu – zb' May 07 '18 at 05:35

@Alper this is the most likely cause of the problem. There's something in one of your shell startup scripts that prints .--. along with ANSI escape sequences. You can keep your startup script but edit it to include the check for an interactive shell. See https://unix.stackexchange.com/a/257613/22812 – Anthony Geoghegan May 11 '18 at 17:24

I normally use hostname (DNS name, rather than IP). Please try the below:

scp -rv file.sh dest@host@DNS:/home/user/foo/

I am actually using DNS name, it didn't make any change. @user227863 – alper May 01 '18 at 11:24

What OS and file system are you running on your remote machine? What are the file attributes before you copy it? Is it readable by everyone?

As a further troubleshooting step, try to copy the file back from your remote machine to your local machine, but name it something else.

scp user@IP:/remote/machine/remoteFile /local/machine/remoteFileRenamed

Ubuntu ext4. Please note that copy operation between host and remote machine does not work. Basically on my host I tried ... and that file didn’t show up on my host machine. @user43633 – alper May 06 '18 at 11:50
