Check These Out
Only tested on Linux Ubunty Hardy. Works when file names have spaces. The "-maxdepth 2" limits the find search to the current directory and the next one deeper in this example. This was faster on my system because find was searching every directory before the current directory without the -maxdepth option. Almost as fast as locate when used as above. Must use double quotes around pattern to handle spaces in file names. -print0 is used in combination with xargs -0. Those are zeros not "O"s. For xargs, -I is used to replace the following "{}" with the incoming file-list items from find. Echo just prints to the command line what is happening with mv. mv needs "{}" again so it knows what you are moving from. Then end with the move destination. Some other versions may only require one "{}" in the move command and not after the -I, however this is what worked for me on Ubuntu 8.04. Some like to use -type f in the find command to limit the type.
Benchmark a SQL query against MySQL Server.
The example runs the query 10 times, and you get the average runtime in the output. To ensure that the query does not get cached, use `RESET QUERY CACHE;` on top in the query file.
Converts any number of seconds into days, hours, minutes and seconds.

If you know the URL of a file on a SharePoint server, it's just a matter of logging in with your AD credentials to get the file with cURL
I like the fact the Patola's version uses only ones and zeros, but I also like the sparse output of the other versions. This one combines both of those features and eliminates some unnecessary cruft.
You can vary the sparseness by changing "$(($RANDOM % 5))" to another number. The number in this term "$(($RANDOM % 4))" controls how frequently the numbers are output bold.
For slow flash memory (cheap thumb drive), ext4 is the fastest stable file system for all use cases with no relevant exception:
http://www.linuxplanet.com/linuxplanet/tutorials/7208/1
Since we can usually dispense with the benefits of a journal for this type of storage, this is a way to achieve the least awful I/O-speed.
Disabling the journal for an existing ext4 partition can be achieved using
$ tune2fs -O ^has_journal /dev/sdXN
Note that it is often recommended to format removable flash media with ext2, due to the lack of a journal. ext4 has many advantages over ext2 even without the journal, with much better speed as one of the consequences. So the only usecase for ext2 would be compatibility with very old software.
Little faster alternative.
This option makes a copy of your current db and via ssh it transfer to the server you specify and upload the database to the specific User & Password you specify (Note the db User & Pass, can be different from the one you use in the other server)
If you are going to use "localhost" as your main db remove (-h) and youst add "localhost"
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"
