Yes I did:
$ cat ~/.shrc
# shell settings
umask 022
set -o emacs
# environment
export BROWSER=lynx
export CVS_RSH=ssh
export HISTSIZE=1000
export HISTFILE=~/.history
export LESS="-g -i -M"
export PAGER=less
export PS1="\...@\h:\W\$ "
export XENVIRONMENT=~/.Xresources
export LC_ALL=C
# aliases
unalias -a
alias ls='ls -p'
alias ll='ls -lAp'
alias mtr='mtr -t'
(In fact, I just converted to ksh from bash,
where lot of automatic shit needed to be got rid of.
The automatic aliases of ksh are pretty useful OTOH.)
Anyway, 'hash' is just an alias, as is e.g. 'suspend'.
Why is it that 'hash' is described as a separate command
in the 'Command execution' section, but 'suspend' is not?

Now I appreciate the nonintended insider point
of 'type' being just an alias for 'whence -v' :-)
Thank you
