Sends the microphone input from PC1 to the speakers of PC2. Do the same in reverse to have an actual conversation ;) ... maybe with another port tough

I know there are a lot of random password generators out there, but I wanted something that put out something besides hex. Set count equal to the number of bytes you want.

Dashboard is OS X utility application. When you hit F12, Dashboard springs forward, dimming the background, some people have claimed memory or performance problems. In my case, I just don't use it, there may be other reasons you?d rather not have Dashboard available.

Change YES to NO to restore the previous functionality.

In Mac OS 9, the "New Folder" keyboard shortcut was Command+N, but in Mac OS X this was changed to "New Finder Window" instead, with "New Folder" taking the more awkward shortcut of Command+Shift+N. This command reverses their mappings.

Mac OS X 10.5 (Leopard) introduced a new, 3D, reflective Dock. For those of us who prefer the Dock to be a little less distracting, this command is the answer. The Dock will be rendered in the same style as when pinned to the left- or right-hand side of the screen. Replace YES with NO to restore the 3D Dock.

If you need to delete all redundant ".svn" directories from a given path and all its subdirectories, use this command !

Particulary useful if you want to upload to an ftp server, but don't use svn or if you need to update/backup some source code to another directory.

You can also try "svn export . /new/path/without/svn/dirs" (also from the CLI)

2009-02-17 22:53:07
User: starchox
Functions: wget

-p parameter tells wget to include all files, including images.

-e robots=off you don't want wget to obey by the robots.txt file

-U mozilla as your browsers identity.

--random-wait to let wget chose a random number of seconds to wait, avoid get into black list.

Other Useful wget Parameters:

--limit-rate=20k limits the rate at which it downloads files.

-b continues wget after logging out.

-o $HOME/wget_log.txt logs the output

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"

If you are using an xterm emulation capable terminal emulator, such as PuTTY or xterm on Linux desktop, this command will replace the title of that terminal window. I know it is not nice to have seventeen terminals on your desktop with title PuTTY, you can not tell which one is connected to which server and doing what.

Even though the string between the quotes is typed as literals, it needs a little more finesse to make it work. Here is how it is done key-by-key:

echo "( ctrl-v then ctrl-[ )0;Enter_Title_String_Here( ctrl-v then ctrl-g )"( enter )

ctrl-v : means hold down ctrl key and hit v at the same time like you are pasting in windoze ; also please don't type the parentheses, i.e., ( and )

ps -ef | grep $USERNAME | awk {'print $2'} | xargs kill [-9]

This is a 'killall' command equivalent where it is not available.

Prior to executing it, set the environment variable USERNAME to the username, whose processes you want to kill or replace the username with the $USERNAME on the command above.

Side effect: If any processes from other users, are running with a parameter of $USERNAME, they will be killed as well (assuming you are running this as root user)

[-9] in square brackets at the end of the command is optional and strongly suggested to be your last resort. I do not like to use it as the killed process leaves a lot of mess behind.

Show you the list of files of current directory sorted by date youngest to oldest, remove the 'r' if you want it in the otherway.

You'll want to use this for passwordless logins. Same as ssh-copy-id, if you don't have it on your system.

find /home -uid 1056 -exec chown 2056 {} \;

find . -size +10240k -exec ls -l {} \; | awk '{ print $5,"",$9 }'|sort -rn > message.out
2009-02-17 19:39:56
User: rommelsharma
Functions: awk find ls
5

This command specifies the size in Kilobytes using 'k' in the -size +(N)k option. The plus sign says greater than. -exec [cmd] {} \; invokes ls -l command on each file and awk strips off the values of the 5th (size) and the 9th (filename) column from the ls -l output to display. Sort is done in reversed order (descending) numerically using sort -rn options.

A cron job could be run to execute a script like this and alert the users if a dir has files exceeding certain size, and provide file details as well.

Use ^D instead of exit.

Also ^D ends input stream when you use terminal for typing into standard input.

Dumps a MySQL database over a compressed SSH tunnel and uses it as input to mysql - i think that is the fastest and best way to migrate a DB to a new server!

If you use symlinks a lot, especially nested symlinks, this puts you back on the absolute path to command-line-fu-nirvana. (Note the backticks around pwd).
