Hello Kevin!

What you need to do in shell is:
unset TEST

(unset )

Good luck.

you can use:

unset test

to unset a variable. you don't really need to unset this variable unless you are going to have your script read for this variable again. Basically by this I mean if you have your script do something and print the date along with your action.... and want the action to repeat... but with the current date printed each time with it.

you can also unset multiple variables at the same time if you wish to.

unset test1 test2 test3

omg you are doing that only for get some points ....

[John Collier]

Malleron,

I don???t know about you, but I don???t see that post as being nothing more than an attempt to get some points. I personally feel that John was simply expanding on the issue above and beyond what the previous replies revealed. I know that there is a high possibility that some new ???Sys Admin in Training??? may very well be helped by the additional information provided as they search the forums for answers and/or knowledge.

Even if I am incorrect in my thoughts, I am personally more appalled at your attempt to slam a person publicly for any reason.

This is supposed to be a professional forum with professional people. Personally, I don???t feel that you are exhibiting very professional behavior when you make comments like that about other forumers.

That is, of course, just my own personal thoughts on the subject.


Have a nice day???


PS. I am not expecting, nor do I want, any points for this post. Please assign it a 0 (zero).

John,

You're seeing the cleaned up version of this thread. I don't even remember who it was but somebody had replied like 20 times and gotten 10 points for each one. And it was obvious that they weren't a "stuck submit key" syndrom, either, because there were other answers interspersed.

That's what the reference was about.

[John Collier]

If that is truly the case, then I retract my statement.

I can only comment on what I see when I arrive, not what was there that I have never seen.

Please forgive me???

[John Meissner]

unset etc....

unset test

this can be done for multiple variable at the same time.
