DESCRIPTION The inplace extension adds two functions named inplace_begin() and in- place_end(). These functions are meant to be invoked from the in- place.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. One can disable inplace editing selectively by placing inplace=0 on the command line prior to files that should be processed normally. One can reenable inplace editing by placing inplace=1 prior to files that should be subject to inplace editing. BUGS While the extension does attempt to preserve ownership and permissions, it makes no attempt to copy the ACLs from the original file. If the program dies prematurely, as might happen if an unhandled signal is received, a temporary file may be left behind. EXAMPLE gawk -i inplace 'script' files ... gawk -i inplace -f scriptfile files ...
