    Here's a function prototyping script to show you what was talked about today would look like...
    Code:

    Explained:

    First checks the programs needed to do a Paste to a Pastebin, in order of preference. The first two, are not default installed to all flavors, but will paste to paste.ubuntu.com. The next two are default to all flavor's and will paste to termbin.com.

    On the paste, it uses the method related to the preferred program found.

    Re: Inspired

    @MAFoElffen,

    1. nc is in /bin in the versions 16.04 LTS and 18.04 LTS. But in 20.04 LTS and later it is in /usr/bin. So you should check for it also in /bin (which you do in the general system-info script (via type if I remember correctly).



    2. I tested the script in post #291, and had to edit it to make it work. Did you test it in a real computer before uploading?

    After some edits I managed to make 3 of 4 alternatives to upload the report file.

    I removed the tools one after another to make the script select the next one until all four were tested and I checked that there was a fair output suggesting manual uploading.

    Code:
    sudo mv /usr/bin/curl /usr/bin/curlx
    sudo mv /usr/bin/pastebinit /usr/bin/pastebinitx
    sudo mv /usr/bin/wget /usr/bin/wgetx
    sudo mv /usr/bin/nc /usr/bin/ncx
    Alternative 3 with wget failed. See this dialogue and the output created:

    Code:
    $ ./paste-test 
     Sensitive data is [REMOVED] from the report file 
    Do you want to upload the report file fo 'https://paste.ubuntu.com'? (y/N) y
    Uploading '/home/olle/system-info.txt' to 'https://paste.ubuntu.com'
    This may take 1-2 minutes...
    
    3
            |./paste-test: rad 74: varning: kommandoersättning: ignorerade nollbyte i indata
    - Upload successful 
    
    The link to the pastebin is saved in: '/home/sudodus/system-info-link.log'

    LOL. Works here. Will look at that.
    Code:
    mafoelffen@ubuntu:~/git/MAFoElffen1/system-info$ which wget
    /usr/bin/wget
    mafoelffen@ubuntu:~/git/MAFoElffen1/system-info$ wget --quiet -O- --post-data=$HOME/system-info 'termbin.com:9999'
    https://termbin.com/qepy

    Re: Inspired

    Code:
    "command replacement: ignored zero bytes in input"
    So... It looks like if I " need to catch error messages from "termbin.com" to insure it "is" a successful paste or not. The command works in this locale.

    Can you try it at the command line and see please? It looks more like the script didn't find the file to send (said 0 bytes). Maybe it's complaining about spanning over several lines?
    Code:
    function PasteWget()
    {
        return_url=$(wget --quiet -O- --post-data=$report 'termbin.com:9999' )
        check_paste=$?
    }
    Another reason for wget preference over nc, because like curl, I can tune it for retries and timeouts, to allow for possible slow connections.

    Re: Inspired

    Did testing on the Paste options...

    Attached is the test script... At the end of the script was the outputs and URL's. And I confirmed the URL's that the system-info Reports were successfully posted at those URL's

    Like sudodus got as a script warning on this code I protoyped yesterday... When using wget and nc in a script, if I use variables for the report location, i get this warning
    Code:
    ./Paster4.sh: line XX: warning: command substitution: ignored null byte in input
    when it is doing the variable expansion... But it completes successfully. The Line Number corresponds to the line of the command. If I hard code it, it goes away.

    I think if I can somehow suppress that warning, somehow, then we are golden... But not sure "how" yet...

    It is a BASH script warning. Not stderr. Looking into that.


    EDIT:
    Success.

    The system-info.txt report is terminated with a \0 null character, and if calling cat from a script also opens another shell from within the script, so on those two,
    Code:
    return_url=$(wget --quiet -O- --post-data="$(tr -d '\0' <$report)" 'termbin.com:9999' )
    ## and...
    return_url=$(tr -d '\0' <$report | nc termbin.com 9999 )
    Read until the null character... That takes care of that... LOL

    Re: Inspired

    +1 I confirm that all 4 alternatives work now, but there are still complaints in my 18.04.5 LTS.

    I solved it this way by removing the null byte in another location. Does it solve it for you too @MAFoElffen?

    1. Your tweak: removing it when reading the report
    2. My tweak: removing it from the output of wget and nc

    Your tweak did not solve it for me. Will my tweak solve the problem for you? Or do we need both tweaks?

    Code:
    $ grep 'return_url.*termbin' Paster4.sh 
        return_url=$(wget --quiet -O- --post-data="`cat $report`" 'termbin.com:9999'  | tr '\0' '\n')
            return_url=$(cat $report | nc termbin.com 9999 | tr '\0' '\n')

    Re: Inspired

    Good that that works for 18.04 there. I Will mod it that way to be backward compatible for 18.04. I'll make sure that works here also.

    So is that how "everyone" wants Paster() to evolve into?

    If so, then I'll work to integrate that into the Master script....

    Re: Inspired

    I tested it not only in 18.04 but also in a 20.04 server with the GA kernel

    Code:
    tester@ubuntu:~$ lsb_release -a
    No LSB modules are available.
    Distributor ID:	Ubuntu
    Description:	Ubuntu 20.04.3 LTS
    Release:	20.04
    Codename:	focal
    tester@ubuntu:~$ uname -r
    5.4.0-84-generic
    and 'my tweak' (without your tweak) works there too with all four uploading tools.

    @ sudodus.: LOL. Right... At least I do give credit where credit is due. I do have much patient, but... I am starting to feel a bit slighted and insulted... Do you mean to be doing that? Or is something else going on? I am a bit confused.

    I also tested it on Server with 5.11.1 and 5.14.2...
