Date: 2016jan11 OS: Linux Q. Linux: How can I find all the executable files in a file tree? A. Use the find command like this:

find /home/myhome -type f -perm /a+x

This looks at everything below folder /home/myhome -type f limits it to just Files since directories are probably going to have the execute (change to) bit set for some user. -perm /a+x has the same syntax as chmod. This means eXecuute for Any user. Once you have found the files you can do something with them. For example, this will remove execute permission:

find /home/myhome -type f -perm /a+x -exec chmod a-x {} \;
