mutt command with multiple attachments in single mail unix

Question

My requirement is to attach all the .csv files in a folder and send them in a single mail.

Here is what have tried,

mutt -s "subject" -a *.csv -- [email protected] < subject.txt

The above command is not working (It's not recognizing multiple files) and throwing the error

Error sending message, child exited 67 (User unknown.).
Could not send the message.

Then I tried using multiple -a option as follows,

mutt -s "subject" -a aaa.csv -a bbb.csv -- [email protected] < subject.txt

This works as expected. But this is not feasible for 100 files for example. I should be able use it with file mask (as like *.csv to take all csv files). Is there is any way we can use like *.csv in single command?

Thanks

Mutt doesn't support such syntax, but it doesn't mean it's impossible. You just have to build the mutt command.

mutt -s "subject" $( printf -- '-a %q ' *.csv ) ...

The command in $( ... ) produces something like this:

-a aaa.csv -a bbb.csv -a ...
