Lionel Sambuc 84d9c625bf Synchronize on NetBSD-CVS (2013/12/1 12:00:00 UTC)
- Fix for possible unset uid/gid in toproto
 - Fix for default mtree style
 - Update libelf
 - Importing libexecinfo
 - Resynchronize GCC, mpc, gmp, mpfr
 - build.sh: Replace params with show-params.
     This has been done as the make target has been renamed in the same
     way, while a new target named params has been added. This new
     target generates a file containing all the parameters, instead of
     printing it on the console.
 - Update test48 with new etc/services (Fix by Ben Gras <ben@minix3.org)
     get getservbyport() out of the inner loop

.Sh NAME
.Nm seq
.Nd print sequences of numbers
.Sh SYNOPSIS
.Nm
.Op Fl w
.Op Fl f Ar format
.Op Fl s Ar string
.Op Fl t Ar string
.Op Ar first Op Ar incr
.Ar last
.Sh DESCRIPTION
The
.Nm
utility prints a sequence of numbers, one per line
.Pq default ,
from
.Ar first
.Pq default 1 ,
to near
.Ar last
as possible, in increments of
.Ar incr
.Pq default 1 .
When
.Ar first
is larger than
.Ar last ,
the default
.Ar incr
is -1.
.Pp
All numbers are interpreted as floating point.
.Pp
Normally integer values are printed as decimal integers.
.Pp
The
.Nm
utility accepts the following options:
.Bl -tag -width Ar
.It Fl f Ar format
Use a
.Xr printf 3
style
.Ar format
to print each number.
Only the
.Cm A ,
.Cm a ,
.Cm E ,
.Cm e ,
.Cm F ,
.Cm f ,
.Cm G ,
.Cm g ,
and
.Cm %
conversion characters are valid, along with any optional
flags and an optional numeric mimimum field width or precision.
The
.Ar format
can contain character escape sequences in backslash notation as
defined in
.St -ansiC .
The default is
.Cm %g .
.It Fl s Ar string
Use
.Ar string
to separate numbers.
The
.Ar string
can contain character escape sequences in backslash notation as
defined in
.St -ansiC .
The default is
.Cm \en .
.It Fl t Ar string
Use
.Ar string
to terminate sequence of numbers.
The
.Ar string
can contain character escape sequences in backslash notation as
defined in
.St -ansiC .
This option is useful when the default separator
does not contain a
.Cm \en .
.It Fl w
Equalize the widths of all numbers by padding with zeros as necessary.
This option has no effect with the
.Fl f
option.
If any sequence numbers will be printed in exponential notation,
the default conversion is changed to
.Cm %e .

.Sh HISTORY
The
.Nm
command first appeared in
.Tn "Plan 9 from Bell Labs" .
A
.Nm
command appeared in
.Nx 3.0 .
This command was based on the command of the same name in
.Tn "Plan 9 from Bell Labs"
and the
.Tn GNU
core utilities.
The
.Tn GNU
.Nm
command first appeared in the 1.13 shell utilities release.
.Sh BUGS
The
.Fl w
option does not handle the transition from pure floating point
to exponent representation very well.
The
.Nm
command is not bug for bug compatible with the
.Tn "Plan 9 from Bell Labs"
or
.Tn GNU
versions of
.Nm .
