MDB_LOAD(1)MDB_LOAD(1)NAMEmdb_load - LMDB environment import tool
SYNOPSISmdb_load envpath [-V] [-f file] [-n] [-s subdb] [-N] [-T]
DESCRIPTION
The mdb_load utility reads from the standard input and loads it into
the LMDB environment envpath.
The input to mdb_load must be in the output format specified by the
mdb_dump(1) utility or as specified by the -T option below.
OPTIONS-V Write the library version number to the standard output, and
exit.
-f file
Read from the specified file instead of from the standard input.
-n Load an LMDB database which does not use subdirectories.
-s subdb
Load a specific subdatabase. If no database is specified, data
is loaded into the main database.
-N Don't overwrite existing records when loading into an already
existing database; just skip them.
-T Load data from simple text files. The input must be paired lines
of text, where the first line of the pair is the key item, and
the second line of the pair is its corresponding data item.
A simple escape mechanism, where newline and backslash (\) char‐
acters are special, is applied to the text input. Newline char‐
acters are interpreted as record separators. Backslash charac‐
ters in the text will be interpreted in one of two ways: If the
backslash character precedes another backslash character, the
pair will be interpreted as a literal backslash. If the back‐
slash character precedes any other character, the two characters
following the backslash will be interpreted as a hexadecimal
specification of a single character; for example, \0a is a new‐
line character in the ASCII character set.
For this reason, any backslash or newline characters that natu‐
rally occur in the text input must be escaped to avoid misinter‐
pretation by mdb_load.
DIAGNOSTICS
Exit status is zero if no errors occur. Errors result in a non-zero
exit status and a diagnostic message being written to standard error.
