FFINDEX_BUILD

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.
