Learn how to use a host of Linux commands in these 2-minute video tutorials from Sandra Henry-Stocker, author of the Unix as a Second Language blog.
In this video transcript, Sandra Henry-Stocker discusses how to calculate factorials on a Linux system. She explains that factorials are the multiplication of numbers starting with a specified number and decreasing incrementally until reaching 1. To calculate factorials on Linux, you can use commands like "seq" and "bc." The "seq" command is used to generate a list of sequential numbers, and the "bc" command is used to perform the factorial calculations.
In this episode, Sandra Henry-Stocker, author of the "Unix as a Second Language" blog on NetworkWorld, explores the use of the "nohup" (no hangup) command in Linux.
In this episode, Sandra Henry-Stocker, the author of the "Unix as a Second Language" blog on NetworkWorld, introduces various ways to use the Linux date command. She demonstrates how to use the "date" command to display the current day of the week, date, time, and time zone.
In this Linux tip, we’re going to look at several ways to increment and decrement numeric variables in bash.
In this Linux tip, we’re going to look at a way that you can view every Nth line in a text file – whether every other line, every third line, every eleventh line or whatever you want to see.

In this Linux tip, we’re going to look at how you can get your command history to omit commands when you enter them more than once in a row.
In this Linux tip, we’re going to look at using the more command to view text files a selected number of lines at a time.
In this Linux tip, we’re going to look at the greater than and greater than x2 operators and how they work. The greater than operator will take the output of the command preceding it and put it into the file that follows it.
In this Linux tip, we’re going to look at setting up sudo privileges for users on Fedora. The key is to make them members of the “wheel” group.
In this Linux tip we will learn how to encrypt using Vim
In this Linux tip, we will look at how to move around on the Linux command line. There may be some tricks that you don’t know.
In this video, we're going to take a look at how you can search for commands in your command history -- in reverse order – and then rerun one.
In this video, we're going to take a look at the grep command and some of the things you can do with it.
In this Linux tip, we’re going to look at the netstat -s command that displays network statistics. The numbers reflect activity since the system’s last boot so some counts will change fairly frequently.
In this Linux tip, we’re going to look at the df -Th command. It provides details on your file systems but, unlike du -h, it adds the file system type – a good thing to take a look at from time to time and understand.
In this Linux tip, we’re going to look at the fortune command. Yes, fortune. It’s a command that will tell you your fortune though, I have to admit, it’s entirely random.
