4Fairly large files (the command files) are built in this directory during
5the test runs, and even larger files (the database files) are created in
6"/var/tmp". If the latter directory doesn't exist, set the environmental
7variable TMPDIR to a directory where the files can be built.

10The script file consists of lines with an initial character which is
11the command for that line, or an initial character indicating a key
12or data entry for a previous command.
13
14Legal command characters are as follows:
15
16c: compare a record
17 + must be followed by [kK][dD]; the data value in the database
18 associated with the specified key is compared to the specified
19 data value.
20e: echo a string
21 + writes out the rest of the line into the output file; if the
22 last character is not a carriage-return, a newline is appended.
23f: set the flags for the next command
24 + no value zero's the flags
25g: do a get command
26 + must be followed by [kK]
27 + writes out the retrieved data DBT.
28o [r]: dump [reverse]
29 + dump the database out, if 'r' is set, in reverse order.
30p: do a put command
31 + must be followed by [kK][dD]
32r: do a del command
33 + must be followed by [kK] unless R_CURSOR flag set.
34S: sync the database
35s: do a seq command
36 + must be followed by [kK] if R_CURSOR flag set.
37 + writes out the retrieved data DBT.
38
39Legal key/data characters are as follows:
40
41D [file]: data file
42 + set the current data value to the contents of the file
43d [data]:
44 + set the current key value to the contents of the line.
45K [file]: key file
46 + set the current key value to the contents of the file
47k [data]:
48 + set the current key value to the contents of the line.
49
50Blank lines, lines with leading white space, and lines with leading
51hash marks (#) are ignored.
52
53Options to dbtest are as follows:
54
55 -d: Set the DB_LOCK flag.
56 -f: Use the file argument as the database file.
57 -i: Use the rest of the argument to set elements in the info
58 structure. If the type is btree, then "-i cachesize=10240"
59 will set BTREEINFO.cachesize to 10240.
60 -o: The rest of the argument is the output file instead of
61 using stdout.
62 -s: Don't delete the database file before opening it, i.e.
63 use the database file from a previous run.
64
65Dbtest requires two arguments, the type of access "hash", "recno"
66or "btree", and the script name or "-" to indicate stdin.
