At command

Wendy Stein — Thu, 11 Sep 2003 13:18:02 GMT

I am running this command:

$ at -f script.sh now

script.sh contains:

$mailx -s "Job Completed" $username<$filename

If $filename contains more than 378 characters in it, then the user will receive an e-mail with NO the subject line AND another e-mail goes to the user who ran the script with the following message :

/var/tmp/mailxCAA.....: file too large
**************************************
Cron: The previous message is the standard output and standard error of one of your at commands.

If I run this script without using 'at', it is fine. If the file sent is 377 or less characters, it is also fine. Once I go over 378 characters, I consistently get the error.

Is there some limitation when using the at command and sending an e-mail ?????

Hi,
did you try the following ?

cat $filename | mailx -s "Job Completed" $username

I know that's quite the same, but the redirection is used in another way, and i used this always with no problem.

Yes I have and this gives me the same results.

I have just run the same script against a file with 11776 lines and 2109500 characters and it worked fine. What version of sendmail are you using? are all patches applied to your version of Unix?

Wendy,

I don't have any insights for you, but, reading the responses so far, I'm sensing some confusion about what the actual question is.

Are you saying that the actual name of the file contains over 378 characters (I pity the poor person who has to type that out) or the contents of the file exceed 378 characters?

Is it possible that you are filling up /var/tmp ?

Re: At command

Wendy Stein — Thu, 11 Sep 2003 14:46:58 GMT

Ok... I am not filling /var/tmp up,
The filename is 5 characters, but the contents are > 378 characters and
I am running version 8.8.6 of sendmail .....

I have solved my own problem. Thanks to all that gave suggestions. The problem was the /var/adm/cron/.proto file with the ulimit.
I changed the ulimit value and now it is fine.

Wendy, what did you change the ulimit parameter to be? how did you find out about the .proto file?

I found a resolution using the search in hp technical knowledge base and got to this

http://www2.itrc.hp.com/service/cki/docDisplay.do?docLocale=en_US&docId=200000065678246

I put this code in but still had a problem so I just hardcoded the ulimit in the .proto file to 4194303.
