NAME
lookbib - find references in a bibliographic database SYNOPSIS
lookbib database DESCRIPTION
A bibliographic reference is a set of lines, constituting fields of bibliographic information. Each field starts on a line beginning with a `%', followed by a key-letter, then a blank, and finally the contents of the field, which may continue until the next line starting with `%'. The lookbib utility uses an inverted index made by indxbib to find sets of bibliographic references. It reads keywords typed after the `>' prompt on the terminal, and retrieves records containing all these keywords. If nothing matches, nothing is returned except another `>' prompt. It is possible to search multiple databases, as long as they have a common index made by indxbib(1). In that case, only the first argument given to indxbib is specified to lookbib. If lookbib does not find the index files (the .i[abc] files), it looks for a reference file with the same name as the argument, without the suffixes. It creates a file with a .ig suffix, suitable for use with fgrep (see grep(1)). lookbib then uses this fgrep file to find refer- ences. This method is simpler to use, but the .ig file is slower to use than the .i[abc] files, and does not allow the use of multiple reference files. FILES
