Disclosure: While I feel that this is a valid topic for New Linux User, I must disclose that I am the founder of the Linux World Net blog network.
Now, onto the nitty gritty.
There are so many people out there blogging in the Linux space, but they’re scattered hither and yon. Linux World Net is my […]
Found the Tux image gallery on LWN today while trolling through Linux Questions.
Some neat ones in there :)

I think this is the last command in the redirection series. I’ve written about redirection and piping, which are great tools to either send command output somewhere other than normal, or to make the output of one command the input of another. What if you wanted to do two things with the output of a […]
I’ve discussed redirection which is the process of telling a command line application to either write its output or take its input from a stream other than what it normally would. The ls command normally writes its output to the screen, for example, but by using redirection you can redirect that output to a file […]
Recirection is a technique that can be used with command line applications in most (all?) Unix-like operating systems. There are three standard interfaces that any command line application can make use of: the standard input, the standard output, and the standard error. We’re not going anywhere near the standard error today, but the other two […]
I find this particular wildcard operation to be so cool that it needs its own entry. I’ve already written about the more common BASH wildcard tokens, but this next one uses the {brace} character to expand entire file names like so:
touch file_{one,two,three}
This command will create (or update the timestamp on them if they exist) the […]
We’re all familiar with some of the more common wildcard characters like * and ?, but most shells offer a lot more than that.
First off, there’s some invisible magic that most of us probably don’t care about, but should be mentioned. When your hacking away at the command line, you’re actually operating within a ’shell’. […]
There are two options at your disposal to remove directories depending on whether you want to remove a single directory or an entire tree: rm -d or rmdir -p.
rm -d foo will remove the foo directory even if it is not empty. However, you must be root to use this command.
rmdir -p foo will remove […]
Wget is an “unattended downloader” application. What does this mean? Well, you can use wget to grab files off the network using the http, https, ftp, and possibly some other protocols It’s designed to be non-interactive meaning that it doesn’t require any user intervention once launched. A simple command like:
wget http://www.somehost.com/files/somefile.tar.gz
will download somefile.tar.gz to my […]
The mkdir command is one of the staples of file management on any GNU/Linux system. As it (kinda) sounds, mkdir makes directories. A typical command that I use is:
mkdir somedir
Some things that I didn’t know about mkdir is that you can assign permissions at creation time and you can create a tree of subdirectories right […]
