I don't know if it's bug or not.
I'm trying to use "filter -kng", specifying an alias which is the one that contains the filter command :

alias ex filter -kng file ex /pcre/

I use a "if ($1 !isnum)" statement coupled with an "else" statement to determine whether I do call the alias manually or the filter command does,
and I'm confused seeing that "echo $1" displays the whole line and not only the number that the 'n' filter flag adds.
Instead, using $token($1,1,32) displays the number only.ks.

It has always worked like that and rightfully so imo; by storing the entire line in $1, multiple spaces are preserved (they wouldn't be if the line was tokenized to $1-).

If you don't care about multiple spaces, then you may want to consider just using /tokenize to split it into parts.

ok thx
