Inline Shell Script with a For Loop

Often I'm asked how to traverse a list of items in a file. You can easily go through a list of items using a for loop. Here's an example of copying selected contents of originalDir to destinationDir via the command line.

#sh
#for i in `cat /home/esofthub/mylist.dat`
#do
#cp -pr /originalDir/$i /destinationDir/.
#echo $i done
#done

sh – shell

cat – lists each item in the list one iteration at a time

cp – the copy utility for a local workstation (plain files and directories, no symbolic links)

-pr – these options preserve the permission, "p" and copies recursively, "r"

echo – lists the item copied

wbar: a quick luanch bar( similar to avant and cairo dock)

wbar is a quick-launch bar (not a dock) that has an appearance similar to Avant Window Manager and Cairo Dock. It is GTK (Gnome) based but can work in all desktop environments. It does not require a compositing manager to be installed and is therefore quicker and more suitable for low-end hardware systems. It is the default in the Google gOS desktop and is available as a .deb package from Google. Download and install (from the command-line Terminal): wget http://wbar.googlecode.com/files/wbar_1.3.3_i386.deb sudo dpkg -i wbar_1.3.3_i386.deb Start wbar with custom start options (e.g. by pressing alt+F2). Here is an example: wbar -isize 48 -j 1 -p bottom -balfa 40 -bpress -nanim 3 -z 2.5 -above-desk Here is another example: wbar -above-desk -pos bottom -isize 60 -nanim 1 -bpress -jumpf 0.0 -zoomf 1.5 For a full list of command-line startup options, see: wbar --help Tip: If you want the "wave" effect just increase the -nanim value. I like the icons to just pop up so I do...
