NAME
mdb-tables - Get listing of tables in an MDB database SYNOPSIS
mdb-tables [-S] [-1 | -d delimiter] database DESCRIPTION
mdb-tables is a utility program distributed with MDB Tools. It produces a list of tables contained within an MDB database in a format suitable for use in shell scripts. OPTIONS
-S Show system tables. System tables are generally those beginning with 'MSys' -1 specifies that the tables should be listed 1 per line. -d delimiter specifies an alternative delimiter. If no delimiter is specified, table names will be delimited by a tab character, or by newline if the -1 option was specified. NOTES
ENVIRONMENT
MDB_JET3_CHARSET Defines the charset of the input JET3 (access 97) file. Default is CP1252. See iconv(1). MDBICONV Defines the output charset. Default is UTF-8. mdbtools must have been compiled with iconv. MDBOPTS semi-column separated list of options: o use_index o no_memo o debug_like o debug_write o debug_usage o debug_ole o debug_row o debug_props o debug_all is a shortcut for all debug_* options HISTORY
mdb-tables first appeared in MDB Tools 0.3. SEE ALSO
gmdb2(1) mdb-export(1) mdb-hexdump(1) mdb-prop(1) mdb-sql(1) mdb-ver(1) mdb-array(1) mdb-header(1) mdb-parsecsv(1) mdb-schema(1) AUTHORS
The mdb-tables utility was written by Brian Bruns. BUGS
Access allows for tables to have spaces embeded in the table name. You must specify a delimiter (-d) if you intend on piping the output of mdb-tables to a program such as awk or cut. 0.7 13 July 2013 MDBTools(1)
