      4 Fairly large files (the command files) are built in this directory during
      5 the 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
      7 variable TMPDIR to a directory where the files can be built.

     10 The script file consists of lines with an initial character which is
     11 the command for that line, or an initial character indicating a key
     12 or data entry for a previous command.
     13 
     14 Legal command characters are as follows:
     15 
     16 c: 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.
     20 e: 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.
     23 f: set the flags for the next command
     24 	+ no value zero's the flags
     25 g: do a get command
     26 	+ must be followed by [kK]
     27 	+ writes out the retrieved data DBT.
     28 o [r]: dump [reverse]
     29 	+ dump the database out, if 'r' is set, in reverse order.
     30 p: do a put command
     31 	+ must be followed by [kK][dD]
     32 r: do a del command
     33 	+ must be followed by [kK] unless R_CURSOR flag set.
     34 S: sync the database
     35 s: do a seq command
     36 	+ must be followed by [kK] if R_CURSOR flag set.
     37 	+ writes out the retrieved data DBT.
     38 
     39 Legal key/data characters are as follows:
     40 
     41 D [file]: data file
     42 	+ set the current data value to the contents of the file
     43 d [data]:
     44 	+ set the current key value to the contents of the line.
     45 K [file]: key file
     46 	+ set the current key value to the contents of the file
     47 k [data]:
     48 	+ set the current key value to the contents of the line.
     49 
     50 Blank lines, lines with leading white space, and lines with leading
     51 hash marks (#) are ignored.
     52 
     53 Options 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 
     65 Dbtest requires two arguments, the type of access "hash", "recno"
     66 or "btree", and the script name or "-" to indicate stdin.
