more complex ones. All those commands work on Linux, macOS, WSL, and anywhere you have a UNIX environment. I hope the contents of this book will help you achieve what you want: get comfortable with Linux folder / : 14 cd /etc This command works on Linux, macOS, WSL, and anywhere you have a UNIX environment 15 pwd Whenever you feel lost in the filesystem, call the pwd command to know where you are: bash_profile if you use the Bash shell, depending on the use case. Be careful with quotes if you have variables in the command: using double quotes the variable is resolved at definition time, using single

folder / : cd /etc This command works on Linux, macOS, WSL, and anywhere you have a UNIX environment 5. pwd Whenever you feel lost in the filesystem, call the pwd command to know where you are: bash_profile if you use the Bash shell, depending on the use case. Be careful with quotes if you have variables in the command: using double quotes the variable is resolved at definition time, using single quotes terminal. We can append the output to a file: echo "hello" >> output.txt We can interpolate environment variables: echo "The path variable is $PATH" Beware that special characters need to be escaped with

without saving Becoming root user Using sudo command !! trick Setting up hostname Environment variables Setting up environment variable values locate command Finding date/time in different timezones Bash history $ sudo hostnamectl hostname fastbox Environment variables Environment variables are a way to pass data on to applications. We can set values of different variables, which any application can then access access. There are various variables which decide how the shell will behave. To see all the variables, use the printenv command. $ printenv ... long output You can execute the same command once as normal

One important option during the installation is whether or not to install a graphical desktop If you choose not to select the“Desktop environment”task, you will only have a relatively basic, com- mand line driven system. Installing the Desktop environment task is optional because in relation to possible but is only ad- vised for experienced users. It is possible to run a graphical desktop environment on older or low-end systems, but in that case it is recommended to install a window manager that
