file filename

The file command indentifies file types based mostly on the magic number

Reading the question another way:

Within shell you can test whether a file is executable.

if [ -x "${filename}" ]
then
      echo "This file is executable : ${filename}"
fi

Using "find" you can find all the files which are executable. For example.

find . -type f \( -perm -000100 -o -perm -000010 -o -perm -000001 \) -exec ls -ald {} \;

then
echo Executable.
else
echo Not executable.
fi

I am becoming concerned about the number of decidely weird commands on from scripterworld which are filtering onto this site. From the above link about "find" we see:

find . -ipath "./SCRIPTS/scripter*" -print

Which version of unix will accept this command?
There is a naive belief on this site that all unix and Linux commands are common.

Btw, this is not commercial quality script:

if test -x filename
then
echo Executable.
else
echo Not executable.
fi
