Adding a Date Element to a Backup
|
|
|
|
|
Whenever I backup a file I like to add a date to the end instead of just BackUp or BU. This is how I do it.
Lets say the file is named foo.bar, simply:
cp foo.bar{,.`date +%F`}
And foo.bar.<yyyy>-<mm>-<dd> will appear in the current folder

Registering the ssh protocol
You need to tell Firefox which program it should use for that particular protocol.
Linux, Mac OS:
Firefox gets its protocol information from its hidden settings.
- In the Location bar, type about:config, and press Enter/Return.
* The about:config "This might void your warranty!" warning page may appear. Click I'll be careful, I promise!, to continue to the about:config page.
- Right-click Hold down the Ctrl key while you click anywhere in the grid, choose New, then String.
- In the Enter the preference name prompt, type in:
network.protocol-handler.app.<my protocol>
(replacing myprotocol with the protocol you want to register) and press OK.
- In the Enter string value prompt, type the path to the program you want the protocol to start and press OK.
Now that the protocol has been registered, try the link again. You may get an External Protocol Request dialog. Click Launch Application. The program you chose should now start.
* Still not working? Make sure that the path you put in the preference is correct. Due to a bug in Firefox, entering an incorrect path will give you the same error message.
Here's the protocol for ssh:
Preference Name: network.protocol-handler.app.ssh
Value: /usr/bin/nautilus

My SPAM folder gets out of hand in a hurry, so here is what I do to keep it under control.
This assumes that all of your spam folders are under a vmail directory, this could be adjusted to suit any base directory.
Move to your /etc/cron.weekly folder, and create a file called clean-spam-folder.sh
cd /etc/cron.weekly
touch clean-spam-folder.sh
chmod guo+x clean-spam-folder.sh
Now add the following to the file you've just created
#!/bin/bash
BASEDIR=/home/vmail
for i in `find $BASEDIR -iname *spam`
do
echo "Moving to $i";
cd $i;
echo "Currently Contains:";
ls;
logger -s -t ClearSPAM "Clearing $i with \"rm -rdf ${i}/*\"";
rm -vrdf ${i}/* | logger -s -t ClearSPAM
echo; echo;
done
This will also log what is done to your syslog.
Done...
