unix support?

[mbauhardt]

Hey, it looks like the history ctrl-r depends on the GNU version of sed/sort/uniq

sed: unknown option -- z
Usage:  sed [-aElnru] command [file ...]
        sed [-aElnru] [-e command] [-f command_file] [-I[extension]]
            [-i[extension]] [file ...]
uniq: unknown option -- z
usage: uniq [-cdu] [-f fields] [-s chars] [input_file [output_file]]
sort: unknown option -- z
usage: sort [-bdfHilmnrSsu] [-k kstart[,kend]] [-o output] [-R char] [-T dir]
             [-t char] [file ...]
   or: sort -C|-c [-bdfilnru] [-k kstart[,kend]] [-o output] [-R char]
             [-t char] [file]
sort: unknown option -- z

any chance to migrate it to support non-gnu version of these tools?

I'm on NetBSD 9.1 (GENERIC)

Indeed it does. Let me try to make this functionality portable.

I'll try to see what I can do in pure mksh, and then move to portable versions of external tools that should be as widely available as possible.

I ported your idea into as a kind of prototype in my dotfiles but with fzy and not fzf on a netbsd.

function __fzy_history__ {
  history 1 | sort -k2 | uniq -f1 | sort -k1nr | sed 's/[[:space:]]/\t/' | fzy -l 25 | sed 's/^[0-9\t]*//'
}

it is working okayish, but I believe the newes dupclicates are removed from the final list, and not the oldest ones.
