Name

Synopsis

gawk -i inplace ...

Description

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



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.

       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 ...
