Note that the behavior with the default FS=" " to skip and delimit using both blanks and newlines, used to be different in older Posix implementations, where blanks were used, but not newlines. mawk and gawk still support this older POSIX defined behavior, with special compatibility command line options.

compare:
Code:
$> echo "1.   222   333.
444.   555.666" | mawk '{print $1}' RS=.
1
222
444
555
666
$>

to
Code:
$> echo "1.   222   333.
444.   555.666" | mawk -W posix_space '{print $1}' RS=.
1
222

444
555
666

$>

Likewise for gawk with the --posix option.

RLM_DBM_PARSE(8)					      System Manager's Manual						  RLM_DBM_PARSE(8)

NAME
rlm_dbm_parse - transforms simple syntax into rlm_dbm format SYNOPSIS
rlm_dbm_parse [-c] [-d raddb] [-i inputfile] [-o outputfile] [-x] [-v] [-q] [username ...] DESCRIPTION
rlm_dbm_parse reads a file of the syntax defined below, and writes a database file usable by rlm_dbm or edits current database. INPUT FORMAT
rlm_dbm_parse reads a format similar to the one used by the files module. In incomplete RFC2234 ABNF, it looks like this: entries = *entry entry = identifier TAB definition identifier = username / group-name username = +PCHAR groupname = +PCHAR definition = (check-item ",")* LF ( *( reply-item ",") / ";" ) LF check-item = AS IN FILES reply-item = AS IN FILES * need definition of username and groupname As an example, these are the standard files definitions (files module). DEFAULT Service-Type == Framed-User Framed-IP-Address = 255.255.255.254, Framed-MTU = 576, Service-Type = Framed-User, Fall-Through = Yes #except who call from number 555-666 DEFAULT Auth-Type := Reject,Service-Type ==Framed-User, Calling-Station-ID == "555-666" #or call number 555-667 DEFAULT Auth-Type := Reject,Service-Type ==Framed-User, Calling-Station-ID == "555-667" To be a valid rlm_dbm input file, it should look like this: DEFAULT Service-Type == Framed-User # (1) Framed-IP-Address = 255.255.255.254, # comma, list cont'd Framed-MTU = 576, Service-Type = Framed-User, Fall-Through = Yes # , end of list Auth-Type := Reject,Service-Type ==Framed-User, # (2) Calling-Station-ID == "555-666" ; # ;, no reply items Auth-Type := Reject,Service-Type ==Framed-User, # (3) Calling-Station-ID == "555-667" ; # ditto This user (the DEFAULT user) contains three entries, 1, 2 and 3. The first entry has a list of reply items, terminated by a reply item without a trailing comma. Entries 2 and 3 has empty reply lists, as indicated by the semicolon. This is necessary to separate an empty line (which is ignored) from the empty list. Definition Fall-Through = Yes used in order to say module to check next record. By default Fall- Through = Yes. OPTIONS
-d raddb Use raddb as the radiusd configuration directory. -i inputfile Use file as the input file. If not defined then use standard input. -o outputfile Use file as the output file. -c Create a new database (empty output file before writing) -x Enable debug mode. Multiple x flags increase debug level. -q Do not print statistics (quiet). -v Print the version and exit. -r Remove a username or group name from the database. SEE ALSO
