grab the output from scp 1

[hokky]

Hi Guys,

Just trying to grab the output from scp like :
abc@... 100% --ETA--

to a logfile.

what I've tried is :

scp [source] [destination] <b>1>logfile.txt</b>

It doesnt work,

any idea ?

 

[hokky]

sorry the bold doesnt work before

scp [source] [destination] <b>1>logfile.txt</b>

 

[hokky]

scp [source] [destination] 1>logfile.txt

scp doesn't display any output if the output device is not a terminal.

While is not exactly what you are looking for, it will "capture" all of the output:

script some.file
- you should then see something like: Script command is started.
- do all the stuff you need to do, scp, etc.
- when done, type: exit
- you should then see something like: Script command is complete.

Everything you did is now in some.file. Do note that the script output will have control characters, etc. in it if/when you vi it.

scp doesn't display any output if the output device is not a terminal.

what about the progress of copying until 100%, you know when scp doing copy the counting until 100%.

That's what I wanna know, just in case it's stuck for some reason.

sbrews,

I dont understand your explanation.

you mean I create a script called "some.file" and where do I see Script command is started ?

can you explain more specific please?

 

[sbrews]

no, script is a command. It records all screen output.

So for example, this:

script scp_transfer.txt
<script file started (or similar message displayed)>
scp some.file user@host:/some/location
(scp does its thing)
exit
<script file finished (or similar message)>

would record everything types/displayed on the screen from the time you hit enter for the script command until you hit enter for the exit command in a file called scp_transfer.txt

what about the progress of copying until 100%, you know when scp doing copy the counting until 100%.

scp will display that progress bar if stdout is to your terminal. But if you try and redirect the output to a file, scp is smart enough to realise that it is not a terminal any more, and does not display the progress bar. The reason is because normally no-one needs to see the progress in a log file, and displaying a progress bar requires use of various screen control codes which would be make a log file messy. If you like you could use the following to produce verbose output, including the duration of the transfer:

[tt]scp -v [source] [destination] > logfile.txt 2>&1[/tt]

Hi Anni,

With using your command,
I couldn't even grab the verbose output...

In the logfile.txt is nothing captured. (

 

[Annihilannic]

Really?? What OS are you on and what shell are you using? Did any output go to the screen? What version of ssh (ssh -V to check)?

Annihilannic.

 

[hokky]

The OS is Redhat,

If I didn't redirect it to output file, the output go to the screen

the version of my ssh is
OpenSSH_3.6.1p2, SSH protocols 1.5/2.0, OpenSSL 0x0090701f

Thx

You mustn't have copied the command I gave you correctly, did you remember the 2>&1 at the end?

[tt]$ ssh -V

Ooo, I thought I don't need to put 2>&1 at the end as I don't want the std error put into the logfile ?

 

[Annihilannic]

Debugging output is sent to stderr, so yes, you do want that in the log file.
