The "ls" command with sorting

The Mac/Unix "ls" command does not include sorting by file name. 

To get it done I added a new function in Bash to my ~/.bash_profile

# ls with sort - updated: February 13, 2018
function list()
{
    if [ "$1" != "" ]; then
        ls -a $1 | sort
    fi
   
    ls -a | sort
}
