sed with literal string--not input file

Question

This should be easy   I want to run sed against a literal string  not an input file   If you wonder why  it is to  for example edit values stored in variables  not necessarily text data   When I do   sed  s       g   A B C    where A B C is the literal which I want to change to A   B   C  I get   Can t open A B C   As though it thinks A B C is a file   I tried piping it to echo   echo  A B C    sed  s       g     I get a prompt   What is the right way to do it

You have a single quotes conflict  so use    echo  A B C    sed  s       g    If using bash  you can do too   lt  lt  lt  is a here-string    sed  s       g   lt  lt  lt   A B C    but not  sed  s       g    A B C    because sed expect file s  as argument s   EDIT   if you use ksh or any other ones    echo string   sed
