SSH Shell and mutiple lines

[Daniel]

I'm trying to use the SSH shell operation to send some commands

send bash
expect .*
send ${echo_command}
expect .*

The problem is tha the echo_command has a lot of break lines

Foe example, something like this.

echo "Test 
123
234
567" > /tmp/test

The problem is that OO doesn't like the line breaks.

I get something like this:

{exception=com.hp.oo.content.ssh.exceptions.SSHException: java.lang.Exception: unsupported operation: Script:currently on line: 4
1 send bash2 expect .*3 send echo "echo "Test 4 123 5 234 6 567" > /tmp/test" > /tmp/test expect .*

I bolded and underlined the steps to be more visible.

There is any way to save the line breaks or to make literal the text I need to add?

[JarodMB]

What about using printf instead of echo? 

printf "Test\n123\n234\n567"

[Daniel]

Well, basically the text I need to write is a certificate. I didn't put it in the original post to explain the problem I'm having with SSH Shell

For example:

-----BEGIN CERTIFICATE-----
MIIDBTCCAe2gAwIBAgIJAPCwOYWI8Yw6MA0GCSqGSIb3DQEBBQUAMBkxFzAVBgNV

-----END CERTIFICATE-----

So using something as printf its the same, because the SSH Shell will get the certificate this way.

Using the SSH Command operation works, but I need to run a previous command before the echo.

[JarodMB]

What about something like below in a command

firstcommand; if [ $? == 0 ]; then echo certstring >> file else echo fail fi

[Daniel]

Well, it was a good option, but it didn't work sorry.

So, I'm trying to import the certificate to the Big IP/F5. If you are familiar with F5 BigIP, they have a tmsh. Its a shell that let you use the F5 commands. In our test environment worked, because the user logged in with bash by default and changed totmsh, but the real environment is configure inverse. You login with tmsh by defualt and need to change to bash.

Basically to leave tmsh you need to write bash, to be able to use echo.

When I tried the command, it gave an error after the bash command.

So I need the shell command and need to find a way to encapsulate the certificate

[JarodMB]

what about something like 

send bash
expect .*
send cat << EOF > tempfile
[certContent]
EOF
expect .*
send var=$(cat tempfile)
expect .*
..... then use how you would in the command using the $var in place of the contents to be echoed 

[Daniel · Accepted solution]

Jarod, thank you very much for your help. Usually in IT, we try to find a solution and sometimes its not the easiest. So I tried to take a look to the whole thing.

Basically the flow involves, requesting the information and installing the certificate 😛
When I add the certificate as an input it adds spaces and then I change it to new lines (\n). I run some filters to have the certificate ready to install (to replace the spaces with newlines).
Instead of adding the new lines, I change it to ---newline---.

I wrote that file on the F5 and after that I make a sed to replace ---newline--- with a \n

I was able to do it the first try using SSH Shell

[David Fidler]

Did you try...

cat <<EOF > /tmp/test
${certstring}
EOF

Note:  The trailing "EOF" must be the only thing on the line, followed by a carriage return.  Or, if you have the text "EOF" in your string, you can use any string for the delimier.. like:

cat <<@@@ > /tmp/test
stuff
@@@
echo it worked

This won't work on windows but you're using unix so...

<edit> - looks like Jarod beat me to it 🙂 </edit>
