Diff command in Unix is used to find the differences between files all types   Since directory is also a type of file  the differences between two directories can easily be figure out by using diff commands  For more option use man diff on your unix box    -b              Ignores trailing blanks   spaces  and  tabs                   and   treats  other  strings  of  blanks  as                  equivalent    -i              Ignores the case of  letters   For  example                    A  will compare equal to  a    -t              Expands  lt TAB gt  characters  in  output  lines                   Normal or -c output adds character s  to the                  front of each line that may adversely affect                  the indentation of the original source lines                  and  make  the  output  lines  difficult  to                  interpret   This  option  will  preserve the                  original source s indentation    -w              Ignores all blanks   lt SPACE gt  and  lt TAB gt   char-                  acters   and  treats  all  other  strings of                  blanks   as   equivalent     For    example                    if   a    b      will   compare   equal  to                   if a  b      and there are many more
