According to the FreeBSD man pages, both these systems have bc. So
this shellscript should work:
function seq -d "Print a sequnce of numbers"
set -l from 1
set -l step 1
set -l to 1
switch (count $argv)
case 1
set to $argv[1]
case 2
set from $argv[1]
set to $argv[2]
case 3
set from $argv[1]
set step $argv[2]
set to $argv[3]
case '*'
printf (_ "%s: Expected 1, 2 or 3 arguments, got %d\n")
seq (count $argv)
return 1
end
for i in $from $step $to
if not echo $i | grep '^-\?[0-9]*\(\|.[0-9]\+\)$' >/dev/null
printf (_ "%s: '%s' is not a number\n") seq $i
return 1
end
end
echo "for( i=$from; i<$to ; i+=$step ) i;" | bc
end
It handles most the things regular seq does. I guess it could be
included with fish inside a test for a regular seq.
