# $NetBSD: README,v 1.1 2011/01/07 15:05:58 pgoyette Exp $ # @(#)README 8.8 (Berkeley) 7/31/94 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. |
