INPLACE(3am)               GNU Awk Extension Modules              INPLACE(3am)




NAME

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


SYNOPSIS

       gawk -i inplace ...


DESCRIPTION

       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  con-
       catenates that suffix onto the original filename and uses the result as
       a filename for renaming the original.


EXAMPLE

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