Chapter III - User's environments and /etc/profile

You have to set up the shell variables, as in

export ORACLE_HOME=...
export ORACLE_BASE=...
export ORACLE_SID=...
and so on.

>2. if the second - bash, what should i do to change shell from sh to bash?

You have to edit the file /etc/passwd

and modify the shell from the posix shell (usr/bin/sh) to bash

And edit the corresponding profile file.

(BTW, the correct punctuation is "/", not "\". "\" is used in windows paths and on Unix for escaping.)

If you use a real shell (sh/ksh), ~/.profile should already be set up. You then can customize it the way you want, as Horia suggested.

Horia and Dennis,
1. i checked passwd. The interpreter is /bin/bash
so why it didnt run the file .bash_pforile? or in passwd must be /usr/bin/bash?

2. my .bash_profile has these values:

# more .bash_profile
MANPATH=/usr/local/share/man:$MANPATH
EDITOR=vi
LESS="-efFKMX"
PS1='\u@\h \W\$ '
# DISPLAY=my_ip:666.0
ORACLE_BASE=/u01/app/oracle
ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1
ORACLE_SID=prod
ORACLE_HOSTNAME=oraprod
NLS_LANG=_.AL32UTF8
TMP=/tmp/$LOGNAME
TMPDIR=/tmp/$LOGNAME
#
PATH=/usr/local/bin:$PATH:$ORACLE_HOME/bin

export PATH MANPATH EDITOR LESS ORACLE_HOME ORACLE_SID ORACLE_HOSTNAME TMP TMPDI R NLS_LANG

test -f ~/.aliases && . ~/.aliases
dat=`date +%Y-%m-%d_%H%M`
umask 022

so if i want to sh/ksh i have to copy these values and paste in .profile or ..?

regards,
rustam

Hello,

The only situation when bash does not interpret the profile file, is when the binary itself is called with --noprofile option.

>or in passwd must be /usr/bin/bash?

You must know where your shell binary exists (if it is /bin/bash or /usr/bin/bash). But if you are able to log into the machine as this user, I believe /bin/bash is your binary used as the shell. (You can use `find` or `which` in order to find out the exact location)



>so if i want to sh/ksh i have to copy these values and paste in .profile or ..?

Yes, you must add the following variables into your .profile:

ORACLE_BASE=/u01/app/oracle
ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1
ORACLE_SID=prod
ORACLE_HOSTNAME=oraprod
NLS_LANG=_.AL32UTF8

export ORACLE_HOME ORACLE_SID ORACLE_HOSTNAME NLS_LANG

Does ~/.bash_profile exist?

Typically there is a tlink that sets /bin to /usr/bin, so both bash paths should be fine.

>export PATH MANPATH EDITOR LESS ...

If you don't have to worry about the Bourne shell, you may want to use:
export MANPATH=/usr/local/share/man:$MANPATH

>if I want to sh/ksh I have to copy these values and paste in .profile or ..?

You can just use ~/.profile and not ~/.bash_profile. Or only put your bash specific stuff in ~/.bash_profile.

Hi Horia and Dennis,
>> The only situation when bash does not interpret the profile file, is when the binary itself is called with --noprofile option.
how can i change noprofile option?

>>You must know where your shell binary exists (if it is /bin/bash or /usr/bin/bash).
bash exist in both directory.

>>I believe /bin/bash is your binary used as the shell.
How can i check current shell?

>> Does ~/.bash_profile exist?
Yeah, ~/.bash_profile exist and i typed content of this file above.

>> only put your bash specific stuff in ~/.bash_profile.
it was\is first way to solve problem, how?

[Dennis Handly]

>how can I change noprofile option?

It isn't likely that option is used at all.

>bash exist in both directory.

More accurately they ARE the same directory.

>How can I check current shell?

ps -fp $$
Or type an invalid command as see if the shell name is in the error message.

>> only put your bash specific stuff in ~/.bash_profile.
>it was/is first way to solve problem, how?

If you always use ~/.profile, it can work for ksh/sh/base. Then if you need some fancy extra stuff for bash, add it to ~/.bash_profile.

Hi Dennis,
the command # ps -fp $$
returned me ... COMMAND
... bash
i determined through the $swlist that bash was installed.

I just want to activate bash and use .bash_profile for my user. Are there specific command to activate bash interpreter? In the passwd file i have this argument.
...:/home/oraprd:/bin/bash

[Patrick Wallek]

>>In the passwd file i have this argument.
...:/home/oraprd:/bin/bash

Then that user will use the bash shell when they log in, if bash is really in the /bin directory.

NOTE: In HP-UX /bin is a link to /usr/bin. /bin/bash will work, if the link is present, but /usr/bin/bash is preferred.

Patrick,
bash exist in /bin, /usr/bin/
when i'm typing wrong command, i get error:
# iffconfig
bash: iffconfig: command not found

so it means my shell is BASH right now. But it doesnt work ~/.profile when i switch
between users.

Rustam
