NAME

       ffindex_build - build file index from files in directories

DESCRIPTION

       USAGE:   ffindex_build   [-a|-v]   [-s]   [-f   file]*  OUT_DATA_FILE  OUT_INDEX_FILE  [-d
       2ND_DATA_FILE -i 2ND_INDEX_FILE] [DIR_TO_INDEX|FILE]*

       -a     append files/indexes, also needed for sorting an already existing ffindex

       -d FFDATA_FILE
              a second ffindex data file for inserting/appending

       -i FFINDEX_FILE a second ffindex index file for inserting/appending

       -f FILE
              file containing a list of file names, one per line -f can be specified up  to  4096
              times

       -s     sort  index  file, so that the index can queried.  Another append operations can be
              done without sorting.

       -v     print version and other info then exit

       -h     display this help message

       ENVIRONMENT

              FFINDEX_MAX_INDEX_ENTRIES - allocate memory for this number of entries

   EXAMPLES:
              Create a new ffindex containing all files from the "bar/" directory containing  say
              myfile1.txt, myfile2.txt and sort (-s) it so that e.g. ffindex_get can use it.

              $ ffindex_build -s foo.ffdata foo.ffindex bar/

              Add (-a) more files: myfile3.txt, myfile4.txt.

              $ ffindex_build -a foo.ffdata foo.ffindex myfile3.txt myfile4.txt

              Oops, forgot to sort it (-s) so do it afterwards:

              $ ffindex_build -as foo.ffdata foo.ffindex

   NOTE:
              Compiled  with  a  maximum  key/filename  length  is 63 and default maximum entries
              80000000.  This can be changed in the sources.
