SRC(1)                                                     SRC(1)

          src, Bfn  - find source code for executable

          src [ -n ] [ -s symbol ] file ...

          Bfn fn

          Src examines the named files to find the corresponding
          source code, which is then sent to the editor using B (see
          sam(1)). If file is an rc(1) script, the source is the file
          itself.  If file is an executable, the source is defined to
          be the single file containing the definition of main and src
          will point the editor at the line that begins the defini-
          tion.  Src uses db(1) to extract the symbol table informa-
          tion that identifies the source.

          Src looks for each file in the current directory, in /bin,
          and in the subdirectories of /bin, in that order.

          The -n flag causes src to print the file name but not send
          it to the editor.  The -s flag identifies a symbol other
          than main to locate.

          Bfn finds the definition of all C functions named fn by
          searching the .c files in the current directory.  It prints
          the file name and line number of each match found and sub-
          mits the match to the plumber(4) if it is unique.  Fn can be
          a regexp(6).

          Find the source to the main routine in /bin/ed:

               src ed

          Find the source for strcmp:

               src -s strcmp rc


          db(1), plumb(1), sam(1).

          Bfn requires the source code to follow style(6).
