Using Unix Tutorial website
Who should use Unix Tutorial
This website was created with Unix beginners in mind, and this means that majority of the topics are basic-to-intermediate difficulty level.
If you’re an advanced Unix user or systems administrator, I can’t promise to entertain you much – that being said, you’re free to contact me with your questions and suggestions as I don’t want to limit the material to basics only.
Command Line Examples on Unix Tutorial
All the examples shown on Unix Tutorial pages are meant to be copy-and-paste friendly, with a caveat: you shoul only copy the command part after shell prompt.
For regular-user friendly commands, prompt delimiter is $ sign, for commands executed by root the prompt delimiter is #.
This means in the following example below you should only copy the sudo apt-get install openssh-server part (that I do my best to highlight with bold font).
ubuntu$ sudo apt-get install openssh-server [sudo] password for greys: Reading package lists... Done Building dependency tree Reading state information... Done Suggested packages:
Shell script examples on Unix Tutorial
WARNING: only one-line examples can be safely reused in Unix command line. Shell script examples need to be copied and saved as a plain text file before they can be used. You should not attempt to copy-and-paste a shell script example into your command line to avoid confusion.
For shell script examples, it is assumed that once you create a plain text file and paste the text of a script, you’ll then change the permissions on this file to make it executable.
If you saved a script as /tmp/exampe.sh file, this is the command to make it executable:
ubuntu$ chmod a+x /tmp/example.sh

OS flavors and release versions
Since topics are not limited to a particular flavor or release of Unix-like OS, anything release-specific is usually accompanied with explanations.
Generally, the flavor of an OS used for each example is shown in the command line prompt.
This is, for example, Ubuntu:
ubuntu$ echo "Hello, world!" Hello, world!
And that’s how CentOS command will be presented:
centos$ echo "Hello, world!" Hello, world!
I also have examples from MacOS.
If different hardware architectures are used in a particular post, it will most certainly be highlighted as well.
