simstring - build database and find similar words

SYNOPSIS¶

simstring [OPTIONS]

DESCRIPTION¶

This utility finds strings in the database (DB) such that they have similarity, in the similarity measure (SIM), no smaller than the threshold (TH) with queries read from STDIN. When -b (--build) option is specified, this utility builds a database (DB) for strings read from STDIN.
