/bin/sh does not read profile

Good evening Betram et al.

I've read the discussion thread as far as it went and would like
to share my own solution to a similar problem, mapped onto the
sh topic. Maybe it works.

A little background:

First of all, because my standard dialog shell is the system's
C shell, the files important are /etc/cshrc with the settings,
such as setenv, alias and path, furthermore /etc/csh.login to
be executed after login, and /etc/csh.logout, executed after
logout. Local to the user exist ~/.cshrc, ~/.login and ~/.logout
which are used if present.

In order to make X work properly with these settings, I have
a kind of "two stages mechanism" which consists of the files
~/.xinitrc and ~/.xsession. The first one is used by X (xdm)
to determine what to do after successful user login, e. g.
start some programs and then exec the window manager / desktop
environment.

Note that both files are chmodded executable:

	% ll .xsession .xinitrc
	-rwxr-xr-x  1 poly  pgm  807 Mar  3 02:46 .xinitrc*
	-rwxr-xr-x  1 poly  pgm   43 Apr 27  2006 .xsession*

The ~/.xsession doesn't do anything besides first incorporate
settings from ~/.cshrc and then execute ~/.xinitrc.

	#!/bin/csh
	source ~/.cshrc
	exec ~/.xinitrc

It is shebanged with the shell I want to use, which is the C shell.

If ~/.xsession is called, it's last action is to execute ~/.xinitrc.
If ~/.xsession is NOT called, ~/.xinitrc will be executed anyway.
It does the following:

	#!/bin/sh
	[ -f ~/.xmodmaprc ] && xmodmap ~/.xmodmaprc
	xrandr --size 1400x1050 &
	xrandr --fb 1400x1050 &
	xsetroot -solid rgb:3b/4c/7a

	# ... your initializations 'n stuff here ...

	exec wmaker

Note that this script is shebanged for sh again. Any X terminals
started now (with csh inside) have the settings from ~/.cshrc.



Mapped onto the initial sh problem, I'd suggest to create the
two files mentioned as follows:

~/.xsession:

	#!/bin/sh
	[ -f ~/.shrc ] && . ~/.shrc
	[ -f ~/.profile ] && . ~/.profile
	exec ~/.xinitrc

~/.xinitrc:

	#!/bin/sh
	[ -f ~/.shrc ] && . ~/.shrc
	[ -f ~/.profile ] && . ~/.profile
	my_init_stuff_1
	my_init_stuff_2
	my_init_stuff_3
	exec my_wm_startup

Now any instance of sh started should be aware of the settings.



Finally, please note that I'm not a guru for sh (or bash) because
I do use sh only for scripting, and bash never. :-)
