command line explanation
Hello everyone,
I found this command line in a website:
perl -pi.bak -we's/\z/Your new line\n/ if $. == 2;' your_text_file.txt
With this command line you can insert a new line anywhere you want in a text without overwriting what's in it.
-p causes perl to assume a loop around your file so that you can process it.
i.bak creates a back up file
-w turns on warnings.
-e is the script you want to execute.
Does anyone know what s/\z/ is for?
Thanks a lot.

gtkdoc-mktmpl
gtkdoc-mktmpl(1) General Commands Manual gtkdoc-mktmpl(1)
NAME
gtkdoc-mktmpl -- GTK DocBook documentation generator.
SYNOPSIS
gtkdoc-mktmpl [ See below ]
DESCRIPTION
gtkdoc-mktmpl This creates or updates the template files which contain the manually-edited documentation. (A template is a simple text form
which is filled in with the description of a function, macro, enum, or struct. For functions and macros it also contains fields for
describing the parameters.)
This script reads in the existing templates, found in tmpl/*.sgml, moves these files to tmpl/*.sgml.bak, and then recreates the .sgml files
according to the structure given in the file MODULE-sections.txt.
Any new templates added, or new function parameters, are marked with FIXME so you can do a grep to see which parts need updating.
Any templates which are no longer used (i.e. they are remove from MODULE-sections.txt) are placed in the file tmpl/MODULE-unused.txt. If
they are included again later they are automatically copied back into position. If you are certain that these templates will never be used
again you can delete them from MODULE-unused.txt.
Any parameters to functions which are no longer used are separated from the rest of the parameters with the line <!-- # Unused Parameters #
-->. It may be that the parameter name has just been changed, in which case you can copy the description to the parameter with the new
name. You can delete the unused parameter descriptions when no longer needed.
EXAMPLE
See /usr/share/doc/gtk-doc-tools/examples, for a makefile.am and a configure.in example file.
