i have recently learned how can i use curly braces to run multiple commands using curly braces
for example, i can create 10 files like this,

touch 1..10.txt

or file with odd names,

touch 1..10..2

I can also restart multiple process like,

systemctl restart app9-server,client,test

above command will restart services called, app9-server , app9-client and app9-test

now i have a command with a space in it,

vagrant destroy app9
vagrant up app9
vagrant ssh app9

how can i run above 3 commands using braces?

I tried,

vagrant destroy app9,up app9,ssh app9

and

vagrant destroy,up,ssh app9

but none of them actually works.

Can someone please tell me how can i run these commands using braces?

In none of the cases where you use curly braces in your question are you running multiple commands.

touch 1..10.txt

runs one command on 10 files:

touch 1.txt 2.txt 3.txt 4.txt 5.txt 6.txt 7.txt 8.txt 9.txt 10.txt

The command

systemctl restart app9-server,client,test

is still just one command:

systemctl restart app9-server app9-client app9-test

Brace expansion is used to perform a simple text expansion of one or several strings in a single command.

The three tasks you want to perform must be three separate commands. You may do this in a loop if you wish:

for cmd in destroy up ssh; do
 vagrant "$cmd" app9
done

Try:

eval 'vagrant 'destroy,up,ssh' app9;'

Notice the quotes.
