Dear, engineer!
I'm writing this E-mail to you since I think I've found something
wrong in Ubuntu!
My Operating System here is Ubuntu Kylin
14.04.
I find a question about command 'paste' in command
line.
Support there is a file called "test.txt", and its content is the
next 2 lines:
ab
cd
If I run the command "paste test.txt", the content of this file will
be print at STDOUT. However, when I ran the command "paste test.txt >
test.txt" I found that the file "test.txt" became an empty file. Here comes the
question, what's going on? Can you help me?
Yours faithfully,
Quan Liu from Central South University!
