textql

textql [-sql query] [-header] [-dlm delim] [options] files

textql allows running SQL queries against structured text files such as CSV and TSV. It loads files into an in-memory SQLite database, treating each file as a table, and executes standard SQL queries against them.When -header is specified, the first row is used for column names; otherwise columns are named c0, c1, etc. Multiple files can be loaded simultaneously and joined using SQL JOIN syntax. The -save-to option persists the imported data to a SQLite database file for further analysis. Custom delimiters are supported with the -dlm flag.
