-F     Do not follow symbolic links named as operands unless the -H or -L options are specified. Write  a
       slash  ( '/' ) immediately after each pathname that is a directory, an asterisk ( '*' ) after each
       that is executable, a vertical bar ( '|' ) after each that is a FIFO, and an at sign ( '@' ) after
       each that is a symbolic link. For other file types, other symbols may be written.
