0011 SYNOPSIS
0012 --------
0013 *edb_dump* [*-V*] [*-f* 'file'] [*-l*] [*-n*] [*-p*] [*-a* | *-s* 'subdb'] 'envpath'
0014
0015 DESCRIPTION
0016 -----------
0017
0018 The *edb_dump* utility reads a database and writes its contents to the
0019 standard output using a portable flat-text format understood by the
0020 *edb_load(8)* utility.
0021
0022
0023 OPTIONS
0024 -------
0025
0026 [*-V*]::
0027 Write the library version number to the standard output, and exit.
0028
0029 [*-f*]:: 'file'
0030 Write to the specified file instead of to the standard output.
0031
0032 [*-l*]::
0033 List the databases stored in the environment. Just the names will be listed,
0034 no data will be output.
0035
0036 [*-n*]::
0037 Dump an EXDB database which does not use subdirectories.
0038
0039 [*-p*]::
0040 If characters in either the key or data items are printing characters
0041 (as defined by isprint(3)), output them directly. This option permits users to
0042 use standard text editors and tools to modify the contents of databases.
0043
0044 *Note*: different systems may have different notions about what characters are
0045 considered printing characters, and databases dumped in this manner
0046 may be less portable to external systems.
0047
0048 [*-a*]::
0049 Dump all of the subdatabases in the environment.
0050
0051 [*-s*]:: 'subdb'
0052 Dump a specific subdatabase. If no database is specified, only the main
0053 database is dumped.
0054
0055
0056 EXIT STATUS
0057 -----------
0058 Exit status is zero if no errors occur. Errors result in a non-zero exit
0059 status and a diagnostic message being written to standard error.
0060
0061 Dumping and reloading databases that use user-defined comparison
0062 functions will result in new databases that use the default comparison functions.
0063 In this case it is quite likely that the reloaded database will be damaged
0064 beyond repair permitting neither record storage nor retrieval.
0065
0066 The only available workaround is to modify the source for the
0067 edb_load(1) utility to load the database using the correct comparison functions.
