TeXShop and BibTeX for lazy guys - automatic call of bibtex

If you want to write a larger scientific document, like a diploma or doctoral thesis, you surely will use bibtex for creating your bibliography (and especially for the German guys: don't just copy and paste... but really use a good bibliography).

Just for completeness, a very nice and free client for working with a bibtex database is JabRef, which is available for MacOS, Linux and Windows.

If you work with TeXShop and use bibtex, compiling your document is quite hard work: first you need to set the texmode to "LaTeX", compile it, set it to "bibtex", compile it, set it back to "LaTeX" compile it. Indeed, a lot to point and click. The following tip will add an entry to your TeXShop called "lat-bib-lat", which does exactly this procedure for you:

1. Open "Terminal". This will give you the nerdy mysterious window with the cursor line.
2. Type in (or copy this line, and do a ctrl+click at the cursor position and paste it) and press return afterwards
   
   cd Library/TeXShop/Engines/
   This changes the console to the folder Library/TeXShop/Engines in your home folder.
   
3. Create a file named lat-bib-lat.engine in that specific folder by casting the following command closed by the return key in the terminal window
   
   vi lat-bib-lat.engine
   This creates the file and opens it in a console text editor, so you will see nothing than a cursor with many tildes below.
4. Press the "i"-key once. In the last line of the window "-Insert-" should appear (so you just switched the text editor to insert mode)
5. Copy the following stuff and paste it by an ctrl + click at the cursor position in the Terminal
   
   #!/bin/bash
   pdflatex "$1"
   for file in *.aux ; do
   bibtex $file
   done
   pdflatex "$1"
   pdflatex "$1"
   This is a so-called script which does exactly what you want: execute latex, do bibtex and execute latex again.
6. Press the "Esc" key (which ends the insert mode) and write ":wq" (without quotation marks) followed by a keystroke of return which tells the editor to Write the file and Quit. You now should be back at the console as it was before the "vi"-command.
7. Make the script executable with the command (press return at the end)
   
   sudo chmod a+x lat-bib-lat.engine
   You will be prompted for your password. Sudo is the command to become SUperuser and DO the following command. The command chmod a+x makes the file executable (x) for all.
8. Restart TeXShop - you will now find an entry called lat-bib-lat. If you choose it, your document will be latexed, bibtexed and latexed again

Happy bibtexing.

Remark:
Apparently you need two runs of pdflatex in order to get the correct citations, so the script does two calls of pdflatex after calling bibtex.

Update:
The lat-bib-lat.engine can be found in the drop-down menu where you can choose the profile to be run as can be seen here:
