The limit reading the file from /file is 4095 Bytes, but by fetch is 64512 Bytes
But with my method, on supported hosts, the read is ulimited.

I continue to attribute our misunderstanding not to your unwillingness to listen, but to the poor translation

You can read large files by not using a script to read the file but put the script in the file in a form of a function and import the RSC file.

Exporting large files is possible and rename it then to an RSC file so they can be imported again.

In the end it's just RouterOS, not "eXtendedOS".
Either you use Containers so you do what you like, or you accept that in the end it's a Router, not one Synology or one of the many "SIM Manager" programs....

Exactly, if I wasn't interested, I wouldn't even have answered you.
But what is your native language?

b) Reading the contents of any file into /files and auto-sharing it as a file in ftp and putting it into a variable, is limited to 64512Bytes.

:local sms [ /file get [ find name="sms.txt" ] contents ]
:put $sms

2) Read an external file to the RouterBOARD.

3) Read content (from a file) at most large 65452Bytes (is limited to 30000Bytes if the field is filled on WinBox textarea field).

example big file export code

/system note
set note="..."

For read, just import the file (no matter if have or not .rsc extension) and you can have the correct content with :local varname [/sys note get note]

/system note set note  ( [ /interface lte at-chat lte1 wait=yes input="AT+CMGL=4" as-value ]->"output" );

I guess all (or most) these DyadyaGenya topics will not be unnecessary if sms tool is improved - viewtopic.php?t=191963, it was my first topic on this forum, I should probably need to add link to it into feature request topic.

This was the startingpoint: viewtopic.php?p=819118

:local sms [/system script get "sms.txt" source]; 
:put $sms

And, yes, it's fair question now that Mikrotik sells many LTE devices why they don't parse PDUs as part of /tool/sms.

Well, changing the 4K file limit from content= be a start... @DyadyaGenya and @rextended have come a long way here... to run into yet another limitation & another set of complex scripting to workaround.

Personally I will go with approach: In loop where records are appended to variable for file save, before append record to that variable I will first check size of that variable and if that length of that variable + length of record variable exceeds 4K then I will write current content value into file segment, then assign current record variable into that variable. File segment counter needs to be raised each time when file is saved. At the end you will have files like: sms.txt.1, sms.txt.2, sms.txt.3... which can be merged on other system where are downloaded.

Why consider the volume of a variable, if everything is well written to a file without it. Have you seen my example above? There is exactly the same principle as you described, only without checking the volume of the variable.

I do not argue, the example is not very well designed, but it was one of the first scripts that I wrote and I published it here just so that the @rextended understood what I was talking about.

This was the startingpoint: viewtopic.php?p=819118

I think that it is more correct to continue in this topic, and not in the one where the link is.

I tried doing something like this:

Code: Select all

:local sms [/system script get "sms.txt" source]; 
:put $sms

But it gives an error: "no such item"

execute "/system script get \"sms.txt\" source" file="sms.txt"

@optio Why still self limit to 4096 bytes!? Many people here walked into this limitation for many years and some found little gems in RouterOS which works around problems. One of those is ":execute"

Lets keep it simple, this will store the output of a command or script to a file like it was display in you screen.

Code: Select all

:execute "/ip/route/export" file="test"

It adds the default extension "txt" to the filename, here is that "test"

You can find more about :execute: https://wiki.mikrotik.com/wiki/Manual:S ... l_commands

:execute ":put ([/interface lte at-chat lte1 wait=yes input=\"AT+CMGL=4\" as-value ]->\"output\")" file=sms.txt

Ok, from DyadyaGenya script example correct answer will be then

Code: Select all

:execute ":put ([/interface lte at-chat lte1 wait=yes input=\"AT+CMGL=4\" as-value ]->\"output\")" file=sms.txt

:execute ":put ([/interface lte at-chat lte1 wait=yes input=\"AT+CMGL=4\" as-value ]->\"output\")" file="sms"

Code: Select all

:execute ":put ([/interface lte at-chat lte1 wait=yes input=\"AT+CMGL=4\" as-value ]->\"output\")" file="sms"

No, I wrote "It adds the default extension "txt" to the filename, here is that "test" ".

Code: Select all

:execute ":put ([/interface lte at-chat lte1 wait=yes input=\"AT+CMGL=4\" as-value ]->\"output\")" file="sms"

Code: Select all

:execute ":put ([/interface lte at-chat lte1 wait=yes input=\"AT+CMGL=4\" as-value ]->\"output\")" file="sms"

Works also with .txt extension in file param, then it will not append .txt to filename.

In fact, both options work. And if you tell me how to read the received files, then this will be an almost ideal solution.

I write "almost" because for some reason (maybe it's something wrong with me) after rebooting the router, the file disappears. It has to be copied to another location or renamed.

I checked again and you are correct. I mixed up that by having then a extra extension to the filename "sms.file" --> "sys.file.txt"

What does it have to do with it, I wanted him to specify it, if he wanted...
If you look closely you'll see that the Uncle Женя lives in Chernihiv, and was born on January 17.. (Женя жарт... )
I don't put the year, if he wants he can put it there...

@DyadyaGenya try with this

Do you really think I give a damn if you're Russian, Polish or Ukrainian?

you can use flash of usb storage for persistence, depends on device, to save it on flash use

Code: Select all

file="flash/sms"

Do you really think I give a damn if you're Russian, Polish or Ukrainian?

in one of them, it has a very negative meaning ))))

I hope that your little investigation brought you moral satisfaction and perhaps even physical satisfaction.

in one of them, it has a very negative meaning ))))

The sentence, on purpose, was meant to be negative, to give the appropriate emphasis to the concept: "I just keep seeing a Brother.".

This work for sure, but the file is created after some seconds, or you wait ":execute" to finish it's job, or you do not see instantly the file...

I still don't understand how to read such a file. You're talking about exporting, and as I understood, using notes, but I still couldn't accomplish it.

:if ([find where name=<filename>]) do={...}

:local output ( [ /interface lte at-chat lte1 wait=yes input="AT+CMGL=4" as-value ]->"output" )
:local lenOutput [:len $output]
:local splitSize 4095
:local offset 0
:local part 1

/file
:while ($offset < $lenOutput) do={
  :local nameFile ("sms".$part.".txt")
  :local end

  :if (($offset + $splitSize) > $lenOutput) do={
    :set end $lenOutput
  } else={
    :set end ($offset + $splitSize)
    :set part ($part + 1)
  }

  add name=$nameFile contents=[:pick $output $offset $end]
  :set offset $end
}

:local part 1
:local input ""
:local done false

/file
:while (!$done) do={
  :local nameFile ("sms".$part.".txt")

  :if ([find where name=$nameFile]) do={
    :set input ($input.[get $nameFile contents])
    :set part ($part + 1)
  } else={
    :set done true
  }
}

:put $input

It is hard to understand what you want to accomplish with all this.

By the way, the option with "execute" for writing suits me just fine. But I don't understand if it allows appending and how to read from it

If you need to load large file from external system you can provide it over http and fetch it chunked or split file into segments and upload to device.

(for this you can use :execute and save all data into single file) over ftp that can be fetched from other system.

One way of "appending" to a file that may be suitable for your purpose is to use /log to log the message at some severity, and define a logging action and corresponding logging destination (for that severity and "script" topic) to write these messages to a file.
Of course it will put date/time on the messages but you may even want that.

The data will definitely be transmitted and stored on another system, which will be the main system. However, I hope to create a sufficiently resilient system with multiple safeguards. And I hope that one of those safeguards will be MikroTik.

:execute allows to put serveral different stuff in one file. The file is then self contained and does need a external script to run, it uses the import command in ROS.

That's makes it ideal for distribution of data to many routers.

I meant for Asus routers. Wrong forum I see now. Sorry.

Safeguards regarding networking is MikroTik device domain, but for some advanced approach of data processing which will be provided to main system, I will suggest to run/create some software/scripts in container which is also on same device but you have more flexibility/ability to process data there and deliver to main system, if you have such device that can run containers.

I have a vague understanding of what a container is. Could you provide a couple of links where, in your opinion, it is explained in beginner-friendly language?
