NAME¶
editmap - query and edit single records in database maps for sendmail
SYNOPSIS¶
editmap [
-C file] [
-N] [
-f] [
-q|-u|-x]
maptype mapname key [ "value ..." ]
DESCRIPTION¶
Editmap queries or edits one record in database maps used by the keyed
map lookups in
sendmail(8). 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. They may be
- dbm
- DBM format maps. This requires the ndbm(3) library.
- btree
- B-Tree format maps. This requires the new Berkeley DB library.
- hash
- Hash format maps. This also requires the Berkeley DB library.
If the
TrustedUser option is set in the sendmail configuration file and
editmap is invoked as root, the generated files will be owned by the
specified
TrustedUser.
Flags¶
- -C
- Use the specified sendmail configuration file for looking up the
TrustedUser option.
- -N
- Include the null byte that terminates strings in the map (for alias
maps).
- -f
- Normally all upper case letters in the key are folded to lower case. This
flag disables that behaviour. This is intended to mesh with the -f flag in
the K line in sendmail.cf. The value is never case folded.
- -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
- Deletes the specific key from the map. Exits with 0 on success or EX_IOERR
on failure.
