mksort - sort the standard input, allowing arbitrarily long lines
/usr/lib/smail/mksort [ -f ] [ file ... ]
Mksort takes lines as input, sorts them by the first field and writes
them to the standard output. The first field is delimited by whitespace
or by the colon character (:). The lines can be of any length, as long
as the entire input can be stored in memory. With -f the sort is
performed independent of case, so that the letter ``A'' compares equal to
the letter ``a'' and ``a'' is always less than ``B.''
If no input files are specified, the standard input is read. In
addition, if a filename of - is given, the standard input is inserted at
The mksort program can be used in combination with mkline(8) to produce
sorted files containing arbitrarily large aliases or paths which can then
be read by a smail(8) pathalias router or aliasfile director. The router
or director should be configured to use the bsearch file access protocol.
See smail(5) for more information on routers and directors.
As an example of the use of mksort with mkline consider a file, aliases,
containing the following aliasing information:
Postmaster: hustead # Ted Hustead, jr.
UUCP-Postmasters: tron, chongo # namei contacts
yamato # kremvax contact
tron: firstname.lastname@example.org (Ronald S. Karr)
yamato: email@example.com (Yamato T. Yankelovich)
chongo: firstname.lastname@example.org (Landon Curt Noll)
Given this file, the command mkline aliases | mksort -f will yield:
mkline(8), mkdbm(8), smail(5), smail(8), pathalias(8).
