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

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

       @load "inplace"

       # Please set INPLACE_SUFFIX to make a backup copy.  For example, you may
       # want to set INPLACE_SUFFIX to .bak on the command line or in a BEGIN rule.

       BEGINFILE {
           inplace_begin(FILENAME, INPLACE_SUFFIX)

       ENDFILE {
           inplace_end(FILENAME, INPLACE_SUFFIX)

       The  inplace  extension adds two functions named inplace_begin() and inplace_end().  These
       functions are meant to be invoked from the inplace.awk wrapper (whose  contents  are  dis‐
       played above) 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 ...
