list directory contents

-l     (The  letter  ell.) Do not follow symbolic links named as operands unless the -H or -L options are
       specified. Write out in long format (see the STDOUT section). When -l (ell) is specified, -1 (one)
       shall be assumed.

-c     Use time of last modification of the file status  information  (see  <sys/stat.h>  in  the  System
       Interfaces  volume  of  IEEE Std 1003.1-2001)  instead of last modification of the file itself for
       sorting ( -t) or writing ( -l).
