[ILUG] zsh and useless uses of cat...

[kevin lyda]

ok, started on zsh this weekend (more free time and all that, natch).
features i've likes so far:

i think recently redhat has started putting /bin in the path prior to
/usr/bin.  this is annoying since it hides /usr/bin/vi from /bin/vi.
so i do this:

    typeset -U path               # makes sure all elements are unique
    for f in $path; do
	if [[ $f != /bin ]]; then
	    tmp=($tmp $f)
	fi
    done
    path=($tmp /bin)
    unset tmp

this puts /bin at the end.  where it belongs in my opinon.  any zsh
wizards know a better way?

prompts are always fun.  this gives user at host(time or ding on the hour)%
on the left hand side, the current dir on the right.

    PS1='%n@%m(%(t.Ding.%D{%l:%M%P}))%# '
    RPS1='%B[%~]%b'

lastly there's the multios option.  ah.  so instead of this:

    cat foo bar | some.cmd
    grep foo bar | tee foo.in.bar | less

you can do:

    some.cmd < foo < bar
    grep foo bar > foo.in.bar | less

and finally there's autocd.  instead of cd .. , you can just do .. .

kevin, typing just that little bit less...
