linux - Find command doesn't work for certain subdirectories

    I just downloaded some source code from a repository and I'm trying to locate a specific file in it. For simplicity, assume that the entire project has the following directory hierarchy

            project
       /       \ 
    src          docs
   /    \             \
other    test2.h        test1.h

    I navigate to the project directory and then use the following command

    sudo find . -name test1.h

    This works perfectly.

    However, the following command doesn't work:

    sudo find . -name test2.h

    The find command is able to locate test1.h but not test2.h. Why could this be? Is it possible for one of the folders to be non-searchable?

    Note, I'm doing all of this on a linux machine

    You don't have the r or x access on src directory.

    use the -executable option:

    find <dir> -executable

    if you want to find only executable files and not searchable directories, combine with -type f:

    find <dir> -executable -type f

    EDIT:

    checking with the comments i see there’s no type x. i’m sorry, this was my mistake. checking for executable files can be done with -perm (not recommended) or -executable (recommended, as it takes ACL into account).

    Use the find's -perm option. This will find files in the current directory that are either executable by their owner, by group members or by others:

    find . -perm /u=x,g=x,o=x

    Edit:

    I just found another option that is present at least in GNU find 4.4.0:

    find . -executable

    This should work even better because ACLs are also considered.

    A file marked executable need not be a executable or loadable file or object.

    Here is what I use:

    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
