Why

[atef_3]

when I append :/sbin/usr to variable PATH in .profile file for any user (other than root) ,I became able to run all the commands
but from root user shell
then run command (su - username)
then run any command
but when I enter to computer under other user
I can not run any command ?

Hi

Change the .profile by the following entry and remove your entry

PATH=$PATH:/sbin/usr

then login su or direct login

If you are using CDE, have a look at

.dtprofile

...
#
# If $HOME/.profile (.login) has been edited as described above, uncomment
# the following line.
#
# DTSOURCEPROFILE=true

I did not understand ur problem :(
Please elaborate...

[atef_3]

Under user other than root ,To run commands such as (ping,telnet,....)
I must change variable PATH . So I changed .profile as
(PATH=$PATH:/usr/sbin:.)
But there are two cases :-
1)-Under user other than root I must
run .profile to run commands (ping,...)
2)-Login to user via root when run
command (su - username)
I can run commands (ping,...)directly
without need to run .profile

(Why ????)

Thank you,,

Hi

the other solution is SUDO

You can run such commands without su is sudo.

This will be very much effective to trace.

First, it would be nice if you chose subjects
more informative than "Why" or "Route".

> I can not run any command ?

What does this mean? What, exactly, do you
do, and what, exactly, happens when you do
it?

> [...] So I changed .profile as

Whose .profile? You didn't actually use the
parentheses ("()"), did you? What _is_ your
PATH in all these cases?

echo $PATH

> [...] when I enter to computer under other
> user

You mean like Telnet, and log in as a
non-root user?

ls -l .profile

What is the user's shell? (Changing .profile
may not do much for a C shell user.)

(To me, it isn't worth doing that, so I always use the absolute path.)

>So I changed .profile as (PATH=$PATH:/usr/sbin:.)

That seems right.

>1)-Under user other than root I must run .profile to run commands (ping,...)

Of course. You must either re-login or you must source .profile to get the changes there.

>2)-Login to user via root when run command (su - username)

This (-) will read .profile. So will using login.

>I can run commands (ping,...) directly without need to run .profile

If you change .profile, you must somehow read it. But you only need to do this once, per login session.
