The editmap command queries or edits one record in a database maps used by the keyed map lookups in sendmail(1M). Arguments are passed on the command line and output (for queries) is directed to standard output.

Depending on how it is compiled, editmap handles up to three different database formats, selected using the maptype parameter. See OPERANDS.

If the TrustedUser option is set in the sendmail configuration file and editmap is invoked as root, the generated files are owned by the specified TrustedUser.

The following options are supported:

-C file

Use the specified sendmail configuration file (file) to look up the TrustedUser option.

-f

Disable the folding of all upper case letters in the key to lower case. Normally, all upper case letters in the key are folded to upper case. This is intended to mesh with the -f flag in the K line in sendmail.cf. The value is never case folded.

-N

Include the null byte that terminates strings in the map (for alias maps).

-q

Query the map for the specified key. If found, print value to standard output and exit with 0. If not found then print an error message to stdout and exit with EX_UNAVAILABLE.

-u

Update the record for key with value or inserts a new record if one doesn't exist. Exits with 0 on success or EX_IOERR on failure.

-x

Delete the specific key from the map. Exit with 0 on success or EX_IOERR on failure.

The following operands are supported:

key

The left hand side of a record.

Each record is of the form:

key value

key and value are separated by white space.

mapname

File name of the database map being created.

maptype

Specifies the database format. The following maptype parameters are available:

dbm

Specifies DBM format maps.

btree

Specifies B-Tree format maps.

hash

Specifies hash format maps.

value

The right hand side of a record.

Each record is of the form:

key value

key and value are separated by white space.
