Store into a file the list of executable files of a system directory

How can i store into a file the list of executable files of a system directory?

My solution is:

if test -f $1 and test -x $1 then
echo $1
else
echo "message"
fi

int a file e.g. test

it runs correctly if i write test filename (only for 1 file),
but i need a solution for all the files of a system directory.

How can i recognize a system directory?

i would appreciate any help

When you post code, please do so using [code] tags. This inproves readability to preserving whitespace and using a fixed width font.

You can iterate over files like this:

Code:

for thisfile in *; do
    if test -f "$thisfile" -a -x "$thisfile"; then
        echo "executable file:            $thisfile"
    else
        echo "not executable or not file: $thisfile"
    fi
done

You can modify the pattern * to examine only some sub-set of files in the directory, e.g.

Code:

for thisfile in *.txt; do
   ...

...to examine only files with a name ending in ".txt".

you can also use find for that .. do 'man find' and take a look at the examples for 'find . -perm'

here's an example statement to list the executable files in a directory:

Code:

find $dir -type f -perm /111 -maxdepth 1
