IF your data includes an arbitrary sequence of blank characters  tab  space   and you want to replace each sequence with one comma  use the following   sed  s   t      g  input file   or   sed -r  s    blank       g  input file   If you want to replace sequence of space characters  which includes other characters such as carriage return and backspace  etc  then use the following   sed -r  s    space       g  input file
