Give us your poor, your tired, your huddled Admins... War Stories
I have been toying with the idea of posting a thread asking for your dumbest mistakes so that we may all learn from each other.
"A smart man learns from his own mistakes,
A wise man learns from others' mistakes"
I think I will start us off. I haven't had too many that were really bad, but here goes. I was playing around on a box as ROOT when I was looking in a certain directory to see what scripts where there.
I was catting them to look but I inadvertently executed one of them when I deleted the cat and left only the command and hit enter by mistake. I didn't notice my handywork right away though. About 15 minutes later, people called me saying they can't login. Anyway, 3 hours later I finally figured out that when I exe that script it changes the permissionsn on your home directory to 444. Well, for me that was /.
Once I fixed that everything was fine.
I had 4 hours of downtime charged to OE, operator error. BTW, this was on a production system at work! Doh!!!

The -ppre argument causes the command to scan for files with pre as the file prefix. You can specify up to 10 arguments. A without any pre following causes all files older than the specified time to be deleted. You must specify at least one argument. Options -ntime Delete all files whose age is more than time, in hours, (default is 72 hours) and that have the specified pre as their file prefix. -m Send mail to the owner of the file when it is deleted. -ssystem Delete files in all directories that are subdirectories of the per system spool directory that exists for system. If ALL is specified, then all system directories are processed. ALL is the default. -ddirectory Delete files that reside in the named directory. The default directory is The option over rides the option. The command typically starts the program. In earlier versions, a deleted work file (C.file) would result in mail to the owner of the work file, regardless of the option. Now, notification of deleted work files is sent to the user ID "uucp". If the option is used, mail is also sent to the owner. Examples Here are some example command lines: # uuclean -pLTMP. -pLOG. -n4 -d/usr/spool/uucp # uuclean -d/usr/spool/uucp/.XQTDIR -p -n # uuclean -smarkie -p -n84 The third example deletes all files for the system that are older than 84 hours.
