how should i remove/delete environments

[rustam_2]

Hi all,
I have environments which were set through CLI
$export .....

I havent configured .bash_profile file, my environments just for this session for now.
Now i need to remove/delete one of the environments. there is not man for export, i couldnt find in other manuals syntax of export.

Would you explain, how can i remove/delete environments with CLI.

Regards,
rustam

Use the command 'unset'.

For example:

$ export ME=you
$ echo $ME
you
$ unset ME
$ echo $ME

$

Thanks, Patrick
i could delete. and now i know this useful command. by the way, i have these environments:
ORACLE_HOME="/u01/app/oracle/product/10.2.0/db_1"
ORACLE_SID="test"

when i typed
$echo ORACLE_HOME
i got
ORACLE_HOME
but not value of ORACLE_HOME

the same with ORACLE_SID
$echo ORACLE_SID
ORACLE_SID

is it wrong?

[Kapil Jha]

are you checking these from oracle user, these variables set for oracle user to startup oracle.

When you echo an environment variable you must preface it with the $ symbol. Notice my examples above.

echo $ME

or

echo ${ME}

The export and unset command do NOT require the $ though.

The bash man page contains information on the export and unset commands (or more accurately shell built-ins).

man

Look for "parameter" and/or "variable".

man

Look for "parameter" and/or "variable".

In the mean time, ...

echo $ORACLE_HOME

[Johnson Punniyalingam]

you have missed " $ " $$-> my 2 cents

# export TERM=vt100
# echo $TERM

Thanks for all.
I could and read a lot about environments. Later i will come back this thread to discussing about .profile for static environments.

If you have a different topic, why not start
a different thread? The cost is low.

Shalom rustam,

There are a lot of scripts to help manage environments, posted to various ITRC threads.

There are helpful tools that can assist the learning process and possibly resolve your issue.
