The replace utility program changes strings in place in files or on the standard input.
Invoke replace in one of the following ways:
shell>replaceshell>fromto[fromto] ... --file[file] ...replacefromto[fromto] ... <file
          from represents a string to look
          for and to represents its
          replacement. There can be one or more pairs of strings.
        
          Use the -- option to indicate where the
          string-replacement list ends and the filenames begin. In this
          case, any file named on the command line is modified in place,
          so you may want to make a copy of the original before
          converting it. replace prints a
          message indicating which of the input files it actually
          modifies.
        
          If the -- option is not given,
          replace reads the standard input and writes
          to the standard output.
        
          replace uses a finite state machine to
          match longer strings first. It can be used to swap strings.
          For example, the following command swaps a
          and b in the given files,
          file1 and file2:
        
shell> replace a b b a -- file1 file2 ...
