That'll work except for the somewhat obscure case where one of arguments is a string consisting entirely of whitespace. You'll lose it when you build up you command variable. This may work better: 

proc my_exec {prog_name args} {
    eval [concat exec $prog_name $args]
}

# test
puts [my_exec ls index.html index-all.html "" ]
