emacs 21.3.1 not loading .emacs

emacs 21.3.1 not loading .emacs

[pranavtiwari]

On my Unix machine, emacs is not loading .emacs.

If I start emacs as:

 % emacs -u $USER

emacs starts up correctly with my .emacs loaded. However, if I start it
without -u option, it ignores my .emacs.

Can someone suggest what the problem could be?

thx,

Maybe emacs is aliased to something else?
For instance, I have df aliased. I can see it by
$ alias df
alias df='df -h'

What do these commands tell you:
C-h v user-login-name
C-h v user-real-login-name
C-h v user-init-file
C-h v init-file-user

Does the problem persist when you start emacs as:
emacs --debug-init

root (wrong)

Where is this picked up from? Help says "The user's name, taken from
environment variables if possible.".  My $USER is set correctly. What
other variable could it be trying to use?

> C-h v user-real-login-name

pranav (correct)

> C-h v user-init-file

nil (i assume default will be meaningful)

> C-h v init-file-user

root

Yes it does.

BTW, when I start emacs with -u pranav, the values are:

user-login-name : root (wrong)
user-real-login-name: pranav (correct)
user-init-file: /users/pranav/.emacs
init-file-user: pranav

user-init-file in the normal case is suspect. Given that .emacs is not
being read, how is it supposed to be set before reading the init file?

The value of the user-login-name variable should be the same as the
result of the user-login-name function; is it?

,----[ C-h f user-login-name RET ]
| user-login-name is a built-in function.
| (user-login-name &optional UID)
|
| Return the name under which the user logged in, as a string.
| This is based on the effective uid, not the real uid.
| Also, if the environment variable LOGNAME or USER is set,

|
| If optional argument UID is an integer, return the login name of the user
| with that uid, or nil if there is no such user.

Again, see the corresponding function:

,----[ C-h f user-real-login-name RET ]
| user-real-login-name is a built-in function.
| (user-real-login-name)
|
| Return the name of the user's real uid, as a string.
| This ignores the environment variables LOGNAME and USER, so it differs 
from
| `user-login-name' when running under `su'.

My guess is that you logged in as root, then su'ed to pranav without the
- argument.

No, it's more complicated than that.  It gets set to t by the
command-line function in startup.el, then reset either to the actual
file name (by a call to load) or to nil (if load can't find the file).

It's not, see the command-line function in startup.el.
