LinuX Command Line Tips
Why do you need to learn the command line anyway? Well, let me tell you a story. Not long ago we had a problem where I work. There was a shared drive on one of our file servers that kept getting full. I won’t mention that this legacy operating system did not support user quotas; that’s another story. But the server kept getting full and stopping people from working. One of the software engineers in our company spent the day writing a C++ program that would look through the directories of all the users and add up the space they were using and make a listing of the results. Since I am forced to use the legacy OS while I am on the job, I installed a version of the bash shell that works on it. When I heard about the problem, I realized I could do all the work this engineer had done with this single line:
du -s * | sort -nr > $HOME/space_report.txt
Graphical user interfaces (GUIs) are helpful for many tasks, but they are not good for all tasks. I have long felt that most computers today do not use electricity. They instead seem to be powered by the “pumping” motion of the mouse! Computers were supposed to free us from manual labor, but how many times have you performed some task you felt sure the computer should be able to do? You ended up doing the work by tediously working the mouse. Pointing and clicking, pointing and clicking.
I once heard an author remark that when you are a child you use a computer by looking at the pictures. When you grow up, you learn to read and write. Welcome to Computer Literacy 101. Now let’s get to work.
