I made a decision to switch to Linux Mint from Ubuntu. After the successful installation I tried to install some of my favorite applications that include Dropbox, Ubutnu One and Google Chrome.
To install Google Chrome, I downloaded the from Google Chrome website and when I double clicked on it to install it gave me following error: [Read more…]
It happened to me a number of times. Usually, I am habitual of using Ctrl+S to save a text editor like Word, Gedit etc. What goes wrong is when I am editing in command line editor such as Vi and I press Ctrl+S or if I accidently press this combination of key. Because it makes the terminal dead, frozen, hanged.
Using Ctrl+S in Linux terminal locks the terminal output and it seems as if the terminal is frozen or hanged. It frustrates the most when it happens for the first time and user is simply unaware of the fact that he has accidently locked the terminal output.
To unlock the terminal output use Ctrl+Q. It will resume the terminal output and put it back to normal.
Hope it helped you. Cheers 
When you install a Perl module, which depends upon other module, in a private directory, you may encounter an error like this:
Can’t locate Perl_Module_Name.pm in @INC (@INC contains: blah blah)
As you can see, INC contains every other thing than the directory where your Perl module is installed.
Try adding the concerned directory in the Perl library path like this:
export PERL5LIB=Path_to_the_Perl_Module_libraryHope it solves your problem.
You want to copy all the contents of a directory (lets say source_dir) which contains lots of other files and subdirectories inside it to another directory (lets say target_dir). If you simply try cp command it may result in the following error:
command: cp source_dir target_dir
output: cp: omitting directory source_dir
If you try recursive copy (using option -r) the directory is copied inside the target directory which you may not be suitable if you want to duplicate the contents of the source directory.
command: cp -r source_dir target_dir
command: ls target_dir
output: source_dir
If you want to copy just the contents of the source directory as in duplicating all its contents use the following command:
command: cp -r source_dir/* target_dirThis command will copy all the content (not the directory itself) in the target directory.
