1 /CONTENT
/CONTENT[=offset-specifier]
/ENV_FROM[=offset-specifier]
/SUBJECT[=offset-specifier]
The /CONTENT, /ENV_FROM, and /SUBJECT qualifiers are used to
specify which frequently occurring fields should be displayed. By
default, only Subject: fields are shown (/SUBJECT). Use /ENV_FROM
to display frequent envelope From: fields or /CONTENT to display
frequent message contents. Any combination of /CONTENT, /ENV_
FROM, and /SUBJECT may be specified. However, only one of each
may be used.
The /CONTENT, /ENV_FROM, and /SUBJECT qualifiers accept the
optional qualifiers START=n and LENGTH=n. These qualifiers
indicate the starting offset and number of bytes in the field
to consider. The defaults are /CONTENT=(START=1,LENGTH=256),
/ENV_FROM=(START=1,LENGTH=2147483647), and
/SUBJECT=(START=1,LENGTH=2147483647). Use of these qualifiers
is useful when, for example, trying to identify occurrences of a
spam message which uses random text at the start of the Subject:
line.
2 /DATABASE
/DATABASE
/DIRECTORY_TREE
Controls whether the message files scanned are only those with
entries in the queue cache database, /DATABASE, or all message
files actually present in the channel queue directory tree,
/DIRECTORY_TREE.
When neither /DATABASE nor /DIRECTORY_TREE is specified, then the
"view" selected with the VIEW command will be used. If no VIEW
command has been issued, then /DIRECTORY_TREE is assumed.
3 /MIN_COUNT
/MIN_COUNT=n
By default, a string must occur at least 2 times, /MIN_COUNT=2,
in order to be displayed.
4 /THREADS
/THREADS=n
/NOTHREADS (default)
The /THREADS qualifier may be used to accelerate searching on
multiprocessor systems by dividing the work amongst multiple,
simultaneously running threads. To run n simultaneous searching
threads, specify /THREADS=n. The value n must be an integer in
the range 1-8. The default is /NOTHREADS.
5 /TOP
/TOP=n
By default, the top 20 most frequently occurring fields are
shown, (/TOP=20).
6 /VERBOSE
/VERBOSE
/NOVERBOSE (default)
The /VERBOSE qualifier may be used to request that the utility
print out information about what it is doing as it operates.
