Hiya...
I need to set a cron entry for root on an IRIX system.
How do I go about this? I already got my script that I want to run at midnight every day except Saturday. It is to perform an rdump to a Solaris Tape Server.

regards.

You can also type
crontab -e
and edit what appears including a line like the suggested in the comment by ozo.
Be sure to set the environmenr variable EDITOR like this Assuming your favorite editor is emacs, if not put vi or whatever you use):
EDITOR=emacs or setenv EDITOR emacs
I dont know how complicated is you script, but if it includes only one dump command you can include this directly in the crontab.

What version of IRIX are we talking about?
crontab -e
works with a sufficiently recent IRIX.
I'd pesonally prefer to edit in any version,
(but then that makes the answer harder to explain:-)

jlms, I'm curious, how did you determine that? I don't see how to tell from the question.
Did rickyr mention it in a previous question?
Or have you had personal contact with rickyr?

Hiya jlms...
Sorry, I should have said that I got IRIX 5.3. I tried what you said....
# crontab -e
      usage is:
      crontab [ file | -l -r ]
also tried...
# crontab root
      usage is:
      crontab [ file | -l -r ]
also tried...
# crontab root -l
      usage is:
      crontab [ file | -l -r ]

The script does the following....
for i in dumpvol1 dumpvol2
do
rdump......etc
done

Then the comment of ozo should be the right answer! Did you try it?

`man crontab` could tell you even more about the usage
But even in absence of a -e flag, I think I'd prefer to edit:

su
emacs /var/spool/cron/crontabs/root
crontab /var/spool/cron/crontabs/root
crontab -l

Hiya....
I did

#crontab -l > root.cron
#vi root.cron
--->edit file here<---
#cat root.cron | crontab

the last bit was from ozo's comment,
so you can come back for your points.
