INPLACE(3am) GNU Awk Extension Modules INPLACE(3am)
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 con- catenates 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 ...
