bib , one starts an interactive shell programme
which allows to search the bibliography, year by year, with one keyword.It first asks for the year (you need to give only two last figures, for example 94) and the subject, which should be a keyword recognised by the database. There is presently no check to say that a keyword exists!
To continue to search the bibliography for the same subject but for another year, simply enter the new year value and "return" for the subject.
Conversely, you can keep the same year with "return" , but change the subject. It is of course possible to change both the year and the subject at the same time.
Answers like "0" , "n" or "fin" put an end to the interrogation.
To know which are the allowed keywords, the
command bib has appropriate options to get
information on keywords.
