GNU find is a powerful command-line utility that lets you search for files and folders in a hierarchical tree directory structure. It is the backend for all those utilities out there like the graphical searching in KDE or GNOME. However, find can be a little hard to handle at first by beginners.

In today's post I'm going to show how to use the command line find program to search for files. There are certainly different GUI tools available in Linux, such as Beagle, to search for files. The advantage of many of these systems is that they index the files on your system so that the searching is rather fast.

The guide aims first-time users and average Linux users and its goal is to make you learn your way around when using the Linux command-line interface (or CLI for short). It also encourages some habits which I believe that, although hard to learn at first, will make you more productive later on.

I decided to try and come up with my own one-liner to remove the old kernels from my system. In this post I'll take you through each portion of this one-liner step by step so you can see how it works.

To remove a file with dashes, slashes or other special characters, the easiest way is to access the file using its inode. To get the inode of a file, just do a ls -li. When you have that number, use find to delete the file using the following command.

It occurred to me that I was running 3 CPU-bound processes on the same machine and that the processes might be stepping on each other's toes. It's possible that if the server is running on core 4 one second and the producer is running there the next, the level 1 cache of that core could be ruined for the server the next time it ambles over there.

I've shown previously how to use the more command to view text output. Today I'll show how to do the same thing with the less command. You can run the command simply by opening a terminal window and entering...

Usually I focus on console programs that include an interface of some sort. But I need to get past that sometimes.
