Dear Bhamu,

I fail to understand the problem.

That combination of statements does not make sense.  If you see the
permissions you state, you have permission to “execute” that file (and
so does every other user since the “a+x” bit is set).

If the problem is that you cannot run the commands, the reason is
somewhere else.  Post the error you are seeing.

If the problem is that you set executable permissions on every file and
want to reverse that, that is harder since you have to figure out which
files “should” have that permission.
