inplace - emulate sed/perl/ruby in-place editing


   gawk -i inplace ...


   The  inplace  extension  adds  two  functions named inplace_begin() and
   inplace_end().  These functions  are  meant  to  be  invoked  from  the
   inplace.awk wrapper which is installed when gawk is.

   By  default, each named file on the command line is replaced with a new
   file of the same name whose contents are the results of running the AWK
   program.   If the user supplies an AWK variable named INPLACE_SUFFIX in
   a BEGIN rule or  on  the  command  line,  then  the  inplace  extension
   concatenates that suffix onto the original filename and uses the result
   as a filename for renaming the original.


   gawk -i inplace 'script' files ...
   gawk -i inplace -f scriptfile files ...
