indxbib - Man Page

indxbib makes an inverted index of the bibliographic databases in each file to speed their access by refer(1), lookbib(1), and lkbib(1). The program writes to a temporary file that it later renames to file.i. If no file operands are present and no -o option is given, indxbib names the index Ind.i.

Bibliographic databases are divided into records by blank lines. Within a record, each field starts with a % character at the beginning of a line. Fields have a one-letter name that follows the % character.

indxbib stores the values set by the -c, -l, -n, and -t options in the index: programs that search the index interpret them, discarding and truncating keys appropriately, and using the original keys to verify that any record found using the index actually contains the keys. This means that a user of an index need not know whether these options were used in the creation of the index, provided that not all the keys to be searched for would have been discarded during indexing and that the user supplies at least the part of each key that would have remained after being truncated during indexing. indxbib also stores the value set by the -i option in the index for use in verifying records found using it.

--help

displays a usage message, while -v and --version show version information; all exit afterward.

-c common-words-file

Read the list of common words from common-words-file instead of /usr/share/groff/1.24.0/eign.

-d dir

Use dir as the name of the directory to store in the index, instead of that returned by getcwd(2). Typically, dir will be a symbolic link whose target is the current working directory.

-f list-file

Read the files to be indexed from list-file. If list-file is -, files will be read from the standard input stream. The -f option can be given at most once.

-h min-hash-table-size

Use the first prime number greater than or equal to the argument for the size of the hash table. Larger values will usually make searching faster, but will make the index file larger and cause indxbib to use more memory. The default hash table size is 997.

-i excluded-fields

Don't index the contents of fields whose names are in excluded-fields. Field names are one character each. If this option is not present, indxbib excludes fields X, Y, and Z.

-k max-keys-per-record

Use no more keys per input record than specified in the argument. If this option is not present, the maximum is 100.

-l min-key-length

Discard any key whose length in characters is shorter than the value of the argument. If this option is not present, the minimum key length is 3.

-n threshold

Discard the threshold most common words from the common words file. If this option is not present, the 100 most common words are discarded.

-o basename

Name the index basename.i.

-t max-key-length

Truncate keys to max-key-length in characters. If this option is not present, keys are truncated to 6 characters.

-w

Index whole files. Each file is a separate record.

indxbib 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.

file.i

index for file

Ind.i

default index name

/usr/share/groff/1.24.0/eign

contains the list of common words. The traditional name, “eign”, is an abbreviation of “English ignored [word list]”.
