FTIMES-DBM-MAKE(1) FTimes Documentation FTIMES-DBM-MAKE(1) NAME ftimes-dbm-make - Create or update a Berkeley database SYNOPSIS ftimes-dbm-make [-F separator] [-o option[,option[,...]]] -d db file [file ...] DESCRIPTION This utility reads one or more input files (see ftimes-dbm-reap(1)) and creates or updates the specified database. Databases are implemented as BTrees and constructed using Perl's DB_File module. Enumerating these databases yields the following format: key|value The primary rule of engagement is that imported key/value pairs trump ex- isting pairs in the database. This is true unless the pairs are identical. In that case the existing pairs are not modified. If the AlwaysInsert op- tion is set, imported pairs always trump existing pairs. Input files are processed in command-line order. Typically, files that are sorted yield much faster load times. OPTIONS -d db Specifies the name of the database to create or update. -F separator Specifies the input field separator. Valid separators include the fol- lowing characters: tab '\t', space ' ', comma ',', colon ':', semi-colon ';', equal sign '=', and pipe '|'. The default separator is a pipe. Note that parse errors are likely to occur if the specified separator appears in any of the field values. -o option,[option[,...]] Specifies the list of options to apply. Currently the following op- tions are supported: AlwaysInsert If a key already exists, its value is overwritten. This option im- proves performance when the database is new or the ForceNew option has been set. Enabling this option, however, disables update tracking. BeQuiet Don't report errors (i.e., be quiet) while processing files. ForceNew Force the specified database to be truncated on open. CAVEATS Databases created from the same input may yield different, but equivalent, DBM files. Generally, DBM files are not portable across different plat- forms and operating systems. Therefore, the recommended method for ex- changing or verifying a database is to dump it to a delimited file (see ftimes-dbm-dump(1)) and operate on that instead. Take care to avoid mixing databaes that are based on different field types (i.e., keys). This can be easy to do if you're not careful.
