Automatic file extension

RouterOS Scripting
1

Hi there,

I’ve noticed that each time I create a new file, RouterOS automatically adds a “.txt” extension.
How can I change this behavior as is not possible to rename file?

2

?, use file=xxxxxxxxxx.yyy

eg :
export file=backup.rsc
export compact file=backup.txt

3

you try this?
always save backup and export in .backup or .rsc

4

How can I create a file and choose my extension?

5

what extension need?

6

any one… html for example

7

Can somebody help me?

I’m having the same problem. I want to create a file called “radio.inf” from a script, and I can’t find a way to do that.

Can anyone form Mikrotik comment on this issue?

I think it depends on how you want to create “a file”.

You can not modify the extension of “known” file types like exports or backups.

If the filename is a custom file, like e.g.

/tool fetch url="http://www.google.de/" mode=http dst-path=test.abc

you can choose the filename yourself.

@zap71, Your post prompted me to try using the fetch command. Since my script runs when the radio is not connected to the Internet, I can’t fetch the file from a remote server. Instead, I used the fetch command to copy the .txt file to a .inf file on the radio, and then remove the .txt file that is no longer useful. My full implementation is as follows:

:local TxtFile "radio.txt"
:local InfFile "radio.inf";

# Create the .txt file
/file print file=$TxtFile
:delay 1

# Update the file contents
/file set $TxtFile contents="Some content"

# Copy the .txt file to the .inf file
/tool fetch address=127.0.0.1 user=admin password="" src-path=$TxtFile mode=ftp upload=no dst-path=$InfFile

# Remove the .txt file that is no longer needed
/file remove $TxtFile

A bit kludgy, but it meets my requirements. Note that the :delay command is needed to give the radio time to create the file before updating it with the custom content.

Ha what a cool idea! :smiley:

old topic, but for someone who will search for a solution in the future:

you should append zero symbol (“\00”) to the end of the string to prevent .txt extension addition

examples:

:local $"myFileNameWithMyExtension" "myFile.anyext";

usage:

/file print file=($"myFileNameWithMyExtension"."\00");

or

/system script print without-paging file=($"myFileNameWithMyExtension"."\00") where name="MyScript";

etc…

NB: DO NOT use “\00” in get clause, just use $“myFileNameWithMyExtension” to check for file properties, ie:

:put [/file get $"myFileNameWithMyExtension" value-name="size"]

As syntax from previous post not valid at least in RoS 7.19.4 +

Posting working example.

:global StoragePath "flash/"
:global FileName "id_ed25519-user.pub"
/file print file=("$StoragePath"."$FileName"."\00")

When you make a necropost from 2 YEARS OLD post to correct someone, you're also must correcting yourself...
...or at least add something useful...

Since 7.16.2 (if not earlier, I don't have any older versions handy), you can create a file with the desired extension... more simply.

/file add name="myfile.myext"

or for force RouterOS for not assign standard file names on export, backup, etc. (completely meaningless to me)
(this for both v6 and v7)

/export file="exportname.myext\00"
/system backup save name="backupname.myext\00"

instead can be useful for create csv file
(also this for both v6 and v7)

# if must be ,
:execute ":put \"a,b\r\nc,d\"" file="filename.csv\00"
# if must be ;
:execute ":put \"a;b\r\nc;d\"" file="filename.csv\00"

Of course, :put "a,b\r\nc,d" can be replaced with any script, or script call, that generates a much more complex CSV file than this example.
It can also be used to create custom .rsc files, not just those created with export, etc., etc., etc.
