ffrroomm -- Command

Generate list of numbers, for use in loop
ffrroomm _s_t_a_r_t ttoo _s_t_o_p [ bbyy _i_n_c_r ]

ffrroomm prints  a list of integers  on the standard output,  one per line.  It
prints   beginning  with   _s_t_a_r_t,  and   then  prints   successive  numbers
incrementing  by _i_n_c_r  (default, one)  the  previous number.   It continues
until the generated value matches or exceeds _s_t_o_p. Each of _s_t_a_r_t, _s_t_o_p, and
optional _i_n_c_r is a decimal integer with an optional leading `-' sign.

Typical uses of ffrroomm include generating  a file of numbers and generating a
loop index for the shell.   The following example creates special files for
eight terminal ports:

for i in `from 0 to 7`
do
    /etc/mknod /dev/hs0$i c 7 $i
done

_S_e_e _A_l_s_o
ccoommmmaannddss, kksshh, sshh

_D_i_a_g_n_o_s_t_i_c_s
ffrroomm prints an error message if the generated list is empty.
