How to Find binary files with or without executable permissions?
I am working on a BASH script that would list in a path:
* Shared Object files,
* scripts, executable files,
* static libraries
It should not display intermediate files like .o (object files).

You mean find all binary ELF files that don't have the execute bit?– Noam RathausCommented Nov 25, 2013 at 12:16

Yes, nrathaus, I have files mixed up under number of directories (like in a tree), they do not have execute permissions: -rw-rw-r--, I know they contain executables, How to find / list executables?– AjayKumarBasuthkarCommented Nov 25, 2013 at 12:18

Welcome to StackOverflow! S.O. provides a mechanism whereby you can ask for help to fix errors in your code. What have you tried?– ghotiCommented Nov 25, 2013 at 12:51

Hi ghoti, Thanks for the warm welcome. I have a bash script, I am looking to display or list files in a directory hierarchy that are actually executable files and they are not marked executable, ya let the script list if they are marked executable as well :)– AjayKumarBasuthkarCommented Nov 25, 2013 at 13:05

Hi gothi & nrathaus, Is there any thing I could do to get +1? Thanks for your support.– AjayKumarBasuthkarCommented Nov 26, 2013 at 5:52

You can use:
find . -type f -print0 | xargs -0 -n 10 file -i | grep "application/x-executable"

It runs relative to your path, go to "/" before running it Commented Nov 25, 2013 at 12:30

It also doesn't filter out those that are already marked as "executable" Commented Nov 25, 2013 at 12:31

Okay, I should list files those that are marked executable for example shared object files .so and others. Commented Nov 25, 2013 at 12:40
The file program reports file type based on contents, so
file /bin/* | awk -F: '/executable/{print $1}'
reports potentially/actually executable files in /bin.

I wish to list all the files in hierarchy. I tried: find ./ -name "*" | xargs file | awk -F: '/executable/{print $1}' Not effective. Commented Nov 25, 2013 at 12:45

I tried the find | xargs | awk pipeline just now, and every file it reported is in some executable format.– arntCommented Nov 25, 2013 at 12:54

And what does file report for these files? See if you can spot a pattern, and change the /foo/ argument to awk.– arntCommented Nov 25, 2013 at 21:25

find . -type f | xargs file | awk -F: '/script/{print $1} /ELF/{print $1}' perhaps?– arntCommented Nov 26, 2013 at 8:01
This worked for me & thought of sharing...
find ./ -type f -name "*" -not -name "*.o" -exec sh -c '
case "$(head -n 1 "$1")" in
?ELF*) exit 0;;
MZ*) exit 0;;
#!*/ocamlrun*)exit0;;
esac
exit 1
' sh {} \; -print
