Single command to create a file and set its permission

Question

I am using the following 2 commands to create a 0B file and set its extn to 644

touch filename.ext
chmod 777 filename.txt

My question is that whether there is any single command in unix (korn shell) that will do the two things together that is to say create a 0B fil with desired permission?

Answer 1

install -m 777 /dev/null filename.txt
