# how to compile bbl file in command prompt

Unfortunately I forgot how to compile the bbl file in CMD to update my bibliography in a TeXwork document. I prefer to modify the bbl file rather then the bib..and if I'm right I have to compile it in the appropriate path in command prompt. Any help?

You don't compile a bbl. bbl is the output of bibtex. –  Ulrike Fischer Nov 5 '13 at 12:54
@UlrikeFischer Yes sorry, bad question. But I remember I could change the bibliography section simply modifying the bbl file and even deleting the bib before running PdfLatex+Makeindex+Bibtex. I used to type a command in CMD (that I found in one of the Latex forum discussion) which allowed texwork to read the updated citations. Anyway thanks for your time. I might create again a .bib file. –  lauda Nov 5 '13 at 13:06
The `.bbl` file is constructed by either `bibtex` or `biber` after an initial run of `latex` on your `.tex` file; it is then read in to your output file (`.pdf` or `.dvi`) on subsequent run(s) of `latex`. So, in theory, you could make minor changes to the `.bbl` and, if you didn't do something invalid, have the changes reflected in the final output (via running `latex` twice more). This would be highly tedious and error-prone to do, however. It is much better to have a proper `.bst` (Bibliography STyle file) do the formatting for you (assuming you are using `bibtex`). –  jon Nov 5 '13 at 14:54
