Rename wires

Well, I'm going to show my Unix bias here, but there are a *lot* of tools available to do things like this built in to Linux and OS X and available for Windows.  It depends how deep you want to go down the rabbit hole!

My first reaction would be to use "sed" the stream editor.  (Do a search for "sed for windows".)  Sed is used at the command line, and takes some input, modifies it, and sends it to some output.  For example,

sed 's/W500/W512' schematic.sch > newschematic.sch

which would change occurrences of W500 to W512 and create a new file called newschematic.sch without changing the original schematic.sch.  To make sure things look good, you could use the "diff" command on the two files to see exactly what was changed.  Of course, you wouldn't want to have to change that command line and re-run it for every substitution you want to make, so it's better to create a sed script file with all the commands you want (somewhat analogous to that CSV file in the referenced article), and then run the command:

sed -f script.file schematic.sch > newschematic.sch

Sed is a great tool and can be used over and over again without having to modify and recompile.  Now, if you want to learn something a little more sophisticated, there is a simple, yet amazing text processing language called AWK.  AWK knows how to read in a text file line by line, split the line into words and do things to those words.  You can do more testing and manipulating than you can in sed.  AWK is very much like the C programming language, so you can do things like printf to create new output.  Then, if you want to really go down the rabbit hole and get into more powerful scripting languages, the big three in my book are PERL, Python and Ruby.  Each has strengths and weaknesses and each has devout followers and detractors.  Let me know if you're interested or do a search to learn more...

BTW, if you don't want to download and install any of these unix tools, you might consider using Windows PowerShell too...

Thank you for your help.

after some tests I found out that Win doesn't like the following command:

sed 's/W500/W5000' 30c.sch 30d.sch

But the following seems to work so far (thank you google):

sed "s/W500/W5000/" 30c.sch 30d.sch

Well, first everything seems to work fine, it reads and schows all data in the 30c file, but after everything has finished, the 30d.sch is still empty. Any idea what I am doing wrong? Sorry I have to admit that I'm not the shell-guy...

As for the advice with the inconsistent board: Thank you for your advice, but there is no board, only the schematic. It is the shematic of my newly build camper. I know, eagle may not be the best solution for doing that, but works so far ok for me...
