.TH SEQ 1
.SH NAME
seq \- print sequences of numbers
.SH SYNOPSIS
.B seq
[
.B -w
]
[
.BI -f format
]
[
.I first
[
.I incr
]
]
.I last
.SH DESCRIPTION
.I Seq
prints a sequence of numbers, one per line, from
.I first
(default 1) to as near 
.I last
as possible, in increments of
.I incr
(default 1).
The loop is:
.sp
.EX
  for(val = min; val <= max; val += incr) print val;
.EE
.sp
The numbers are interpreted as floating point.
.PP
Normally integer values are printed as decimal integers.
The options are
.TP "\w'\fL-f \fIformat\fLXX'u"
.BI -f format
Use the 
.MR print (3) -style
.I format
.IR print
for printing each (floating point) number.
The default is 
.LR %g .
.TP
.B -w
Equalize the widths of all numbers by padding with
leading zeros as necessary.
Not effective with option
.BR -f ,
nor with numbers in exponential notation.
.SH EXAMPLES
.TP
.L
seq 0 .05 .1
Print
.BR "0 0.05 0.1" 
(on separate lines).
.TP
.L
seq -w 0 .05 .1
Print
.BR "0.00 0.05 0.10" .
.SH SOURCE
.B \*9/src/cmd/seq.c
.SH BUGS
Option
.B -w
always surveys every value in advance.
Thus
.L
seq -w 1000000000
is a painful way to get an `infinite' sequence.
