First Post: Output remote server stream bash file with line breaks on page PHP

[kkmoslehpour]

Hi all,

 

I am attempting to output a remote bash file onto a page so the user can see what is happening. I am able to read the bash file, however, anything I try it isn't adding a newline between each echo statements. Does anyone know how to do this?

 

Here is my bash file:

 

    #!/bin/bash

   #!/bin/bash



    echo 'touch /tmp/testfile'."\n"

    echo "I am up\n"

    echo '\n'

    echo "\n"

    echo

    echo 'hello there'

 

Here is my php logic:

 

    if(isset($_POST['option']) && $_POST['option'] == 1) { 

                    $stream = ssh2_exec($connection, "/tmp/user/testscripts/up.sh");

                    stream_set_blocking($stream, true);

                    $stream_out = ssh2_fetch_stream($stream, SSH2_STREAM_STDIO);

                    echo stream_get_contents($stream_out);



               }

 

Here is my output on the page:

 

touch /tmp/testfile.\n I am in up\n \n \n hello there

Am I reading this correctly in that you 'bash file' is the file you are using the ssh calls to retrieve?

 

In that case why does the bash file have all that php code in it?  It would seem that the bash file is simply data and your ssh2 calls are simply supposed to retrieve it. so the echo means nothing.

 

How about trying the example that is in the manual and do a loop that uses fgets to read the stream?

Hi ginerjm,

 

No sorry, to clarify, I have a bash file in a remote server, let's say, script.sh. I have another php file called, main.php that is trying to output the contents of the bash file on to the webpage. Two separate files here. I am able to read the echo's from the remote script.sh, however, the spacing and linebreaks are off. 

 

Thanks

So - what is that "bash file" you posted earlier?

 

I understand more than you think here.  You are attempting to read something that has a bunch of echos in it, no?

It's a shell script. Not sure what's so confusing about that.

 

OP: What do you need the newline sequences for? The Bash echo already terminates each string with a newline. However, PHP scripts by default output HTML, and an ASCII newline is not an HTML newline. Either change the content type of the HTTP response to text/plain or use a <pre> element or convert the newlines to <br> elements.

I found the answer, when you are converting from bash to html you can use the following:

 

                    echo '<pre>' . stream_get_contents($stream_out) . '</pre>';

 

                                                   OR

 

                    echo nl2br(stream_get_contents($stream_out));
