lkbib searches bibliographic databases for references matching all keywords key and writes any references found to the standard output stream. It reads databases given by -p options and then (unless -n is given) a default database. The default database is taken from the REFER environment variable if it is set, otherwise it is /usr/dict/papers/Ind. For each database file to be searched, if an index file.i created by indxbib(1) exists, then it will be searched instead; each index can cover multiple databases.
--help displays a usage message, while -v and --version show version information; all exit afterward.
-i string
When searching files for which no index exists, ignore the contents of fields whose names are in string.
-n
Suppress search of default database.
-p file
Search file. Multiple -p options can be used.
-t n
Require only the first n characters of keys to be given. The default is 6.
lkbib exits with status 0 on successful operation, status 2 if the program cannot interpret its command-line arguments, and status 1 if it encounters an error during operation.
