3To build this portably, try something like:
4
5 make PORTDIR="../PORT/MACH"
6
7where MACH is the machine, i.e. "sunos.4.1.1".
8
9To run the tests, enter "sh run.test". If your system dictionary isn't
10in /usr/share/dict/words, edit run.test to reflect the correct place.
11
12Fairly large files (the command files) are built in this directory during
13the test runs, and even larger files (the database files) are created in
14"/var/tmp". If the latter directory doesn't exist, set the environmental
15variable TMPDIR to a directory where the files can be built.

18The script file consists of lines with an initial character which is
19the command for that line, or an initial character indicating a key
20or data entry for a previous command.
21
22Legal command characters are as follows:
23
24c: compare a record
25 + must be followed by [kK][dD]; the data value in the database
26 associated with the specified key is compared to the specified
27 data value.
28e: echo a string
29 + writes out the rest of the line into the output file; if the
30 last character is not a carriage-return, a newline is appended.
31f: set the flags for the next command
32 + no value zero's the flags
33g: do a get command
34 + must be followed by [kK]
35 + writes out the retrieved data DBT.
36o [r]: dump [reverse]
37 + dump the database out, if 'r' is set, in reverse order.
38p: do a put command
39 + must be followed by [kK][dD]
40r: do a del command
41 + must be followed by [kK] unless R_CURSOR flag set.
42S: sync the database
43s: do a seq command
44 + must be followed by [kK] if R_CURSOR flag set.
45 + writes out the retrieved data DBT.
46
47Legal key/data characters are as follows:
48
49D [file]: data file
50 + set the current data value to the contents of the file
51d [data]:
52 + set the current key value to the contents of the line.
53K [file]: key file
54 + set the current key value to the contents of the file
55k [data]:
56 + set the current key value to the contents of the line.
57
58Blank lines, lines with leading white space, and lines with leading
59hash marks (#) are ignored.

61Options to dbtest are as follows:
62
63 -d: Set the DB_LOCK flag.
64 -f: Use the file argument as the database file.
65 -i: Use the rest of the argument to set elements in the info
66 structure. If the type is btree, then "-i cachesize=10240"
67 will set BTREEINFO.cachesize to 10240.
68 -o: The rest of the argument is the output file instead of
69 using stdout.
70 -s: Don't delete the database file before opening it, i.e.
71 use the database file from a previous run.
72
73Dbtest requires two arguments, the type of access "hash", "recno"
74or "btree", and the script name or "-" to indicate stdin.
