+.SH NAME
+db_dump185 \- dump DB 1.85 legacy database files
+.SH SYNOPSIS
+\fBdb_dump185\fP [\fB-p\fP] [\fB-f output\fP] db_file
+.SH DESCRIPTION
+The
+.I db_dump185
+utility reads the version 1.85 database file
+.I db_file
+and writes it to the standard output using a portable flat-text format
+understood by the
+.IR db_load (1)
+utility.
+The argument
+.I db_file
+must be a file produced using the version 1.85
+.I DB
+library functions.
+.PP
+The options are as follows:
+.TP 5
+.B \-f
+Write to the specified
+.I file
+instead of to the standard output.
+.TP 5
+.B \-p
+If characters in either the key or data items are printing characters
+(as defined by
+.IR isprint (3)),
+use printing characters in
+.I file
+to represent them.
+This option permits users to use standard text editors to modify
+the contents of databases.
+.IP
+Note, different systems may have different notions as to what characters
+are ``printing'', and databases dumped in this manner may be less portable
+to external systems.
+.PP
+Dumping and reloading hash databases that use user-defined hash functions
+will result in new databases that use the default hash function.
+While using the default hash function may not be optimal for the new database,
+it will continue to work correctly.
+.PP
+Dumping and reloading btree databases that use user-defined prefix or
+comparison functions will result in new databases that use the default
+prefix and comparison functions.
+.ft B
+In this case, it is quite likely that the database will be damaged
+beyond repair permitting neither record storage or retrieval.
+.ft R
+.PP
+The only available workaround for either case is to modify the sources
+for the
+.IR db_load (1)
+utility to load the database using the correct hash, prefix and comparison
+functions.
+.PP
+.Ex db_dump
+.SH "OUTPUT FORMATS
+There are two output formats used by
+.IR db_dump .
+.PP
+In both output formats, the first few lines of the output contain
+header information describing the underlying access method, filesystem page
+size and other bookkeeping information.
+This information is output in ``name=value'' pairs, where ``name'' may
+be any of the keywords listed in the
+.IR db_load (1)
+manual page, and ``value'' will be its value.
+While this header information can be edited before the database is
+reloaded,
+there is rarely any reason to do so, as all of this information can be
+overridden by command-line arguments to
+.IR db_load .
+.PP
+Following the header information are the key/data pairs from the database.
+If the database being dumped is of type
+.B btree
+or
+.BR hash ,
+the output will 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.
+If the database being dumped is of type
+.BR recno ,
+the output will be lines of text,
+where each line is a new data item for the database.
+.PP
+If the
+.B \-p
+option was specified, each output line will consist of single characters
+representing any characters from the database that were ``printing'',
+and backslash (``\e'') escaped characters for any that were not.
+Backslash characters appearing in the output mean one of two things:
+if the backslash character precedes another backslash character,
+it means that a literal backslash character occurred in the key or data
+item.
+If the backslash character precedes any other character,
+the next two characters should be interpreted as hexadecimal specification
+of a single character, e.g., ``\e0a'' is a newline character in the ASCII
+character set.
+.PP
+If the
+.B \-p
+option was not specified, each output line will consist of paired hexadecimal
+values, e.g., the line ``726f6f74'' is the string ``root'' in the ASCII
+character set.
+.PP
+In both output formats,
+a single newline character ends both the key and data items.
