Why I need to known, if an executable exists is,
I'm trying to write a program which reads a list of commands from file and
execute, and the format I want is simple, so I fixed to something like this,
hello
echo "hello world!"
echo "hello represents two of us and the below two"
ls
temp
temp
echo "temp here"
echo "If hello is called, even I will be executed"
one can consider hello to be something like a variable, it can hold other
variables and so on (can be deeply nested)...
According to the format, `temp` can either be a executable with no
arguments or some-other variable.
I do known that this is mostly possible to do with shell script, I'm doing
to this just for fun.
