|
|
|
|

|
|
|
c: compare a record
|
|
|
|
|

|
|
|
|
|
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.
|
|
|
|
|

|
|
|
|
|
+ writes out the retrieved data DBT.
|
|
|
|

|
|
|
|
|

|
|

Options to dbtest are as follows:
|
|
|
|
|
|
|
|
|
|
-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.
|
|
|
|
|
|
|
|
|
|
Dbtest requires two arguments, the type of access "hash", "recno" or
|
|
|
|
|
"btree", and the script name.
