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

- The script file consists of lines with an initial character which is
- the command for that line, or an initial character indicating a key
- or data entry for a previous command.
-
- Legal command characters are as follows:
-
- c: compare a record
- + must be followed by [kK][dD]; the data value in the database
- associated with the specified key is compared to the specified
- data value.
- e: echo a string
- + writes out the rest of the line into the output file; if the
- last character is not a carriage-return, a newline is appended.
- f: set the flags for the next command
- + no value zero's the flags
- g: do a get command
- + must be followed by [kK]
- + writes out the retrieved data DBT.
- o [r]: dump [reverse]
- + dump the database out, if 'r' is set, in reverse order.
- p: do a put command
- + must be followed by [kK][dD]
- r: do a del command
- + must be followed by [kK] unless R_CURSOR flag set.
- S: sync the database
- s: do a seq command
- + must be followed by [kK] if R_CURSOR flag set.
- + writes out the retrieved data DBT.
-
- Legal key/data characters are as follows:
-
- D [file]: data file
- + set the current data value to the contents of the file
- d [data]:
- + set the current key value to the contents of the line.
- K [file]: key file
- + set the current key value to the contents of the file
- k [data]:
- + set the current key value to the contents of the line.
-
- Blank lines, lines with leading white space, and lines with leading
- hash marks (#) are ignored.
-
- Options to dbtest are as follows:
-
- -d: Set the DB_LOCK flag.
- -f: Use the file argument as the database file.
- -i: Use the rest of the argument to set elements in the info
- structure. If the type is btree, then "-i cachesize=10240"
- will set BTREEINFO.cachesize to 10240.
- -o: The rest of the argument is the output file instead of
- using stdout.
- -s: Don't delete the database file before opening it, i.e.
- use the database file from a previous run.
-
- Dbtest requires two arguments, the type of access "hash", "recno"
- or "btree", and the script name or "-" to indicate stdin.
