Shouldn't be this difficult. upload file

[jerry...@gmail.com]

Connected to BBB using tty  specifically putty

logged and ls -a give me directory infor.

Trying to upload a file "test.txt" to the BBB from my local computer

Tried all these. nothing works.  What stupid mistake am I making?

Putty is running in the directory that "test.txt" resides.

the directory testing exists in the root on the BBB.  I see it with ls -a

I can cd to it and find no files in it. As it should be.

I try unsuccessfully to upload a file to it.  What am I doing wrong?

root@beaglebone:~/testing# cp test.txt test.txt

cp: cannot stat 'test.txt': No such file or directory

root@beaglebone:~/testing# cp C:\Users\Administrator\Desktop\test.txt /root/testing/test.txt

-bash: AdministratorDesktoptest.txt: command not found

cp: missing destination file operand after 'C:Users'

Try 'cp --help' for more information.

root@beaglebone:~/testing# cp 192.168.13.104:\Users\Administrator\Desktop\test.txt /root/testing/test.txt

cp: cannot stat '192.168.13.104:UsersAdministratorDesktoptest.txt': No such file or directory

Putty connected via a serial connection (aka a tty) doesn't copy files from one machine to another.  Look into something like scp, sftp, winscp, etc. etc. etc.  Those all connect via IP though not serial.

If your main computer is Linux, then you can cp across computers with a common network connection,

But if your main computer is Windows, for small to medium amounts of data ...

I find an easy way is to cd to where you want to create the file.

then 

nano test.txt

then copy the contents of the source file in a windows text editor into the copy buffer

then paste it into nano inside of putty.

Control-X to exit, Yes to save

In the reverse direction, cat the text file you want to export, copy in putty and paste into a suitable file inside of windows.

For larger amounts of data/files, you could put on a uSD card with a FAT file system and mount it in either a Windows computer or a Linux, moving the uSD card back and forth.

Or put the files/data on a USB stick formatted with FAT file system, then move the USB stick back and forth.

When you connect with PuTTY, you are now "on" the beagle, and all
commands only know about the beagle file system.

If you have a file on the host computer, you either have to make the
host computer a mounted file system on the beagle (probably more complex
than you want to consider) OR use a file transfer program

If you are using PuTTY, you should also have it's SFTP client available
(I'm going to demonstrate with an R-Pi as I have it booted -- it's running
a web server, but other than the login and node names, both are versions of
Debian).
