UNIX for Dummies Questions & Answers

Hiya... I've got a script on AIX 4.2 that sends an email, with an attachment, that has always worked happily in the past and has chosen today to stop working. It now throws up an error "/tmp/Rs13492: The file access permissions do not allow the specified action"

The /tmp/RsXXXXX file name indicates to me that it's a temporary file created by mailx as part of the sending process, and I can't think of any reason why it might not work today when it worked last week.

The line of script that appears to be triggering the issue is:
uuencode $filename REV.CSV | mailx -s "$subjectline" address@domain.co.nz

Does anyone have suggestions of what I should be looking for? The RsXXXXX file disappears immediately from /tmp so I can't check the file permissions of it... but it seems like there might be something more fundamentally weird as the mailx command itself appears to be the one failing, rather than a user account trying to access the file mentioned. Any help/ideas would be greatly appreciated... if you need any more info about the problem reply and I'll provide all I can.

What happens when you manually call uuencode and mailx and send some dummy file to your account?
Check if your /tmp still has following permissions:

Code:

drwxrwxrwt      bin      bin

Or if the script is called from another user (cron?) than before?

Thanks for confirming I was right to post in the newbies forum

I had checked that there were universally readable and writeable files in /tmp but didn't actually look at the folder itself which had drwxr-xr-x. Changing the permissions back has worked.
