How to find out which pages need to be updated?

On lfupdate there is function to get the difference between the files on the linuxfocus server and your harddisk. What you need:

• On your harddrive you have a directory tree that is the same as on the server
• Run an inspect on lfupdate and save the result to a file
• cd in front of the directory tree on your harddisk
• Download the lfchkfiles.gz and un-zip it with
  gunzip lfchkfiles.gz; chmod 755 lfchkfiles

Here is an example of how to use lfchkfiles for the German section:

run the command: lfchkfiles lfupdate Deutsch

Note: you are standing in front of the directory Deutsch/ and lfupdate is the output of an inspection of the german section saved as file in the current directory.

To just see the difference run the command:
lfchkfiles lfupdate Deutsch | egrep -v 'ok '| egrep -v 'missing locally'
This looks like:

>files differ in size: Deutsch/January1998/article2.html
>files differ in size: Deutsch/January1998/article4.html
>files differ in size: Deutsch/January1998/article5.html
>files differ in size: Deutsch/January1999/article21.html
>files differ in size: Deutsch/January1999/article4.html
>files differ in size: Deutsch/May1998/article16.html
>WARNING: file on server has size < 100 bytes: Deutsch/News/index.html 
>files differ in size: Deutsch/index.html                              
>files differ in size: Deutsch/indice.html                              
>missing on the server: Deutsch/Archives/lf-de-january1999.tar.gz       
>missing on the server: Deutsch/January1998/Makefile                    
>missing on the server: Deutsch/January1998/example1.c                  
>missing on the server: Deutsch/January1998/example2.c                  
>missing on the server: Deutsch/January1998/example3.c                  
 ----------------                                                       
 0 files missing locally                                                
 5 files not on www.linuxfocus.org                                      
 8 files are equal in name but differ in size                           
 369 files are equal in name and in size                           
 1 files on www.linuxfocus.org with less than 100 bytes            

Building a tar archive from the calculated difference

To get the file name that need updating you run
lfchkfiles lfupdate Deutsch | egrep -v 'ok ' | egrep -v 'missing locally'| grep ':' | sed -e 's/.*: //'
This gives you:

Deutsch/January1998/article2.html                                        
Deutsch/January1998/article4.html                                        
Deutsch/January1998/article5.html                                        
Deutsch/January1999/article21.html                                        
Deutsch/January1999/article4.html                                        
Deutsch/May1998/article16.html                                        
Deutsch/News/index.html                                        
Deutsch/index.html                                        
Deutsch/indice.html                                        
Deutsch/Archives/lf-de-january1999.tar.gz                  
Deutsch/January1998/Makefile                               
Deutsch/January1998/example1.c                             
Deutsch/January1998/example2.c                             
Deutsch/January1998/example3.c                             

To build a tar archive you just need to put the previous command into back-quotes:
tar zcvf patch.tar.gz `lfchkfiles lfupdate Deutsch | egrep -v 'ok '| egrep -v 'missing locally' | grep ':' | sed -e 's/.*: //'`

have fun.
