49 utility prints a sequence of numbers, one per line
56 as possible, in increments of
67 All numbers are interpreted as floating point.
69 Normally integer values are printed as decimal integers.
73 utility accepts the following options:
75 .It Fl f Ar format , Fl -format Ar format
92 conversion characters are valid, along with any optional
93 flags and an optional numeric minimum field width or precision.
96 can contain character escape sequences in backslash notation as
101 .It Fl s Ar string , Fl -separator Ar string
107 can contain character escape sequences in backslash notation as
112 .It Fl t Ar string , Fl -terminator Ar string
115 to terminate sequence of numbers.
118 can contain character escape sequences in backslash notation as
121 This option is useful when the default separator
124 .It Fl w , Fl -fixed-width
125 Equalize the widths of all numbers by padding with zeros as necessary.
126 This option has no effect with the
129 If any sequence numbers will be printed in exponential notation,
130 the default conversion is changed to
136 Generate a sequence from 1 to 3 (included) with a default increment of 1:
137 .Bd -literal -offset indent
144 Generate a sequence from 3 to 1 (included) with a default increment of -1:
145 .Bd -literal -offset indent
152 Generate a sequence from 0 to 0.1 (included) with an increment of 0.05 and padding
154 .Bd -literal -offset indent
161 Generate a sequence from 1 to 3 (included) with a default increment of 1,
162 a custom separator string and a custom terminator:
163 .Bd -literal -offset indent
164 # seq -s "-->" -t "[end of list]\\n" 1 3
165 1-->2-->3-->[end of list]
168 Generate a sequence from 1 to 2 (included) with an increment of 0.2 and
169 print the results with two digits after the decimal point (using a
172 .Bd -literal -offset indent
173 # seq -f %.2f 1 0.2 2
188 command first appeared in Version\~8
196 This command was based on the command of the same name in
197 Plan 9 from Bell Labs and the GNU core utilities.
200 command first appeared in the 1.13 shell utilities release.
204 option does not handle the transition from pure floating point
205 to exponent representation very well.
208 command is not bug for bug compatible with other implementations.
