Move multiple files from command line

15, March 2011

Using find to copy or move multiple files

All the .txt files are located in directories and subdirectories of the ~/tmp folder and I want to copy them to ~/tmp2

To copy them, open a Terminal and use;

$ find ~/tmp -name ‘*.txt’ -exec cp ‘{}’ ~/tmp2 \;

This copies all the files in the original folders and sub folders and saves them to the ~/tmp2 folder.

or to move them,

$ find ~/tmp -name ‘*.txt’ -exec mv ‘{}’ ~/tmp2 \;

this deletes them from the original folders and sub folders and saves them to the ~/tmp2 folder.

Start up Sound

15, March 2011

Start up Sound:

This works on my Xubuntu Natty install. I found a .ogg sound file that I wanted to use as a start up sound so needed an command line ogg player to play it.

$ sudo apt-get install ogg123

Now create a script in /usr/bin as follows [replace mousepad with the text editor of your choice];

$ sudo mousepad /usr/bin/startup

Add the following to the file

#!/bin/sh
#### play sound at startup ####
## reduce volume ##
sleep 5
StartupNotify=false
/usr/bin/amixer -c 0 sset Master,0 60%
## play sound ##
/usr/bin/ogg123 /path_to_my/sartupsound.ogg
## increase volume again ##
/usr/bin/amixer -c 0 sset Master,0 85%

save the script and make it executable with.

$ sudo chmod +x /usr/bin/startup

Now add the script to the system start up, in Xubuntu open [Settings], [Settings Manager], [Session and Startup], [Application Autostart], and then the [Add] button. Add a name of your choice in the Name field, and the same in the Description field, then the path to your script in the Command field i.e /usr/bin/startup in this case the [ok] to finish. You will then get a startup sound next time you log on.

Shutdown Sound

Shutdown Sound:

This works on my Xubuntu Natty install. I found a .ogg sound file that I wanted to use as a shutdown sound so needed an command line ogg player to play it.

$ sudo apt-get install ogg123

now add a script as follow script to /etc/init.d as follows

In a Terminal, create the file with, [change mousepad to your favourite text editor]

$ sudo mousepad /etc/init.d/K99shutdownsound.sh

copy the following into the script

#!/bin/sh
#### play sound at startup ####
## reduce volume ##
amixer -c 0 sset Master,0 50%
## play sound ##
/usr/bin/ogg123 /path_to my/shutdown.ogg

save the script and make it executable.

$ sudo chmod +x /etc/init.d/K99shutdownsound.sh

now add a shortcut to /etc/rc0.d where shutdown scripts go and to /etc/rc6.d where reboot scripts go

$ sudo ln -s /etc/init.d/K99shutdownsound.sh /etc/rc0.d/K99shutdownsound.sh

$ sudo ln -s /etc/init.d/K99shutdownsound.sh /etc/rc6.d/K99shutdownsound.sh

Now I get a reboot and shutdown sound.
