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 ...
