the last person who posted used the most roundabout way to concatinate files, there's a reason there's a "conCATinate" command...

extension to tali713's random fact generator. It takes the output & sends it to notify-osd. Display time is proportional to the lengh of the fact.

Though without infinite time and knowledge of how the site will be designed in the future this may stop working, it still will serve as a simple straight forward starting point.

This uses the observation that the only item marked as strong on the page is the single logical line that includes the italicized fact.

If future revisions of the page show failure, or intermittent failure, one may simply alter the above to read.

The file lastfact, can then be examined whenever the command fails.

Will edit *.db files in the same directory with todays date. Useful for doing a mass update to domains on a nameserver, adding spf records, etc.

Looks for a string starting with 200 or 201 followed by 7 numbers, and replaces with todays date. This won't overwrite Ip's but i would still do some double checking after running this.

Make sure your server's date is correct, otherwise insert your own serial number.

should usually follow this command.

Bash scrip to test if a server is up, you can use this before wget'ing a file to make sure a blank one isn't downloaded.

Just after you type enter, you have 3 seconds to switch window, then "texthere" will be "typed" in the X11 application that has focus. Very useful to beat your score at games such as "How fast can you type A-Z".

The `export` is unnecessary if it's only applicable to the one command.

Like the given command, but combines _DISPLAY=":0.0"_ with _export DISPLAY_ to get _export DISPLAY=":0.0"_ and only imports if DISPLAY is set successfully.

This command will transcode a MythTV recording. The target device is a Google Nexus One mobile phone. My recordings are from a HDHomerun with Over The Air content. Plays back nicely on the N1.

Col 1 is swapped sum in kb

This is a handy way to circumvent the "Maximum line length of 2048 exceeded" grep error.

Once you have run the above command (or put it in your .bashrc), files can be searched using:

Shows how many Windows and Linux devices are on your network.

May add support for others, but that's all that are on my network right now.

Remove security from PDF document using this very simple command on Linux and OSX. You need ghostscript for this baby to work.

A shell function using perl to easily convert Unix-time to text.

Put in in your ~/.bashrc or equivalent.

Tested on Linux / Solaris Bourne, bash and zsh. using perl 5.6 and higher.

We can list the new disk with

The empty file /forcefsck causes the file system check fsck to be run next time you boot up, after which it will be removed.

This works too:

Produces secure passwords that satisfy most rules for secure passwords and can be customized for correct output as needed. See "man pwgen" for details.

This is a bit hacky, but if you're setting up a bunch of new LUNs, it can save a bunch of time. Also check out sfdisk. The fdisk will fail if, for example, a partition table already exists.

Works only on Linux.

Last option (n) turn name of service resolving (/etc/services) off.

or you can add "-x" to get a typical hexdump like output
