This capability will be useful for debugging bash script.
For example, I have a set of commands in a bash script, each of them
output some thing to stdout. However, I can not tell the start and end
of each output. I could have a command that does what I expect
execute.sh to do.
I can easily append each command with 'execute.sh', which will not
only tell me the boundary of each output but also help me remember
what command was executed.
Since what I expect is not possible, the next solution is to use the
eval version which requires to put quote around cmd1, cmd2... But this
is very annoying, when cmd1, cmd2 themselves have the quotation marks,
I have to escape these marks.
So neither solution to execute.sh is ideal, although any of them is
better than the other in certain situations.
