i put the line "source ~/.profile" in my .bashrc;
when i loaded xterm i got a blank screen with no login prompt;

here's the .profile file; notice that it also includes the "export..."
lines for
.inputrc:


~/.profile:
--------------snip----------------
# the default umask is set in /etc/profile
#umask 022

# if running bash
if [ -n "$BASH_VERSION" ]; then
    # include .bashrc if it exists
    if [ -f ~/.bashrc ]; then
        . ~/.bashrc
    fi
fi

# set PATH so it includes user's private bin if it exists
if [ -d ~/bin ] ; then
    PATH=~/bin:"${PATH}"
fi

export INPUTRC=/etc/inputrc
export INPUTRC=/home/hodgson/.inputrc

imputerate replies:
 to clear up a point: i live in emacs with an elaborate set of
keyboard
customizations [inspired in part by the old Wordstar principle: use
geometry instead of mnemotics];

i have them set in my .emacs file;

i also put a small batch of them in .inputrc, so that i would have the
same experience writing on the command line as i do writing in an
emacs
buffer [i also write email messages in gnus];

so, i'm still up a tree about how to get xterm/bash to read .inputrc;

imputerate:
 BUT the variable which has changed is not that my shell is bash, but
that my terminal emulator is xterm [instead of gnometerm];
   [NB on the slackware box, xterm/bash DOES retain the readline
customizations]

joel answered:

imputerate:
if i take my eccentric customizations out of inputrc, then they will
only be in .emacs, which neither xterm nor bash is apt to read; is
this not so?

imputerate writes:
yes; i think so too; i have only face and background for xterm and
emacs in .Xresources, but i wonder if .Xdefaults is also sourced by
some of xterm/bash, anyway for root.

can someone direct me to a discussion of the priorities which obtain
among all these config files; for, example, i understand from several
posts here and there that .Xresources preempts .emacs; thanks,
imputerate
