Navigation mit "cd" und "pwd" | Linux Basics

Summary

In this video, the presenter teaches viewers how to navigate the file system in Linux using the command line. Starting with basic commands like 'pwd' to print the current directory and 'cd' to change directories, the video explains both absolute and relative path navigation. The presenter demonstrates the use of shortcuts such as '.' for the current directory and '..' for the parent directory, as well as using 'cat' to view file contents. Practical examples like moving files with 'mv' are included. The video wraps up with a teaser for the next episode on the Tab key's autocomplete feature.

Takeaways

• 😀 The `pwd` command shows the current directory's absolute path in the terminal.
• 😀 The `cd` command allows you to change directories, and using it without parameters takes you to your home directory.
• 😀 Absolute paths begin from the root directory (e.g., `/home/linBasics`), while relative paths depend on the current directory.
• 😀 The `..` command moves you up one level in the directory structure, and can be used multiple times to go further up.
• 😀 Shortcuts like `.` (current directory) and `..` (parent directory) can be combined to navigate more efficiently.
• 😀 You can view the contents of text files using the `cat` command in the terminal (e.g., `cat dog.txt`).
• 😀 The `mv` command is used to move files from one directory to another, and you can specify relative paths when moving files.
• 😀 Using the Tab key for auto-completion in the terminal helps reduce typing errors and speeds up navigation.
• 😀 Navigating directories in the shell is easy once you understand the basics like `cd`, `pwd`, and `ls`.
• 😀 The `ls` command lists the contents of a directory, and can be used to inspect files within the current directory.
• 😀 Proficiency in the shell makes navigating and managing files in Linux efficient and less prone to mistakes.

Q & A

What command is used to check the current directory in the Linux shell?

The command 'pwd' (Print Working Directory) is used to check the current directory in the Linux shell.

What does the 'cd' command do in the Linux shell?

The 'cd' command stands for 'change directory'. It is used to navigate between different directories in the shell.

What is the purpose of the 'tilde' symbol (~) in the shell?

The tilde (~) symbol represents the home directory in the Linux shell. It is a shortcut used to quickly navigate to the user's home directory.

What does the command 'cd ~' do?

The command 'cd ~' takes you to your home directory. It's a shortcut for navigating to the directory designated for your user profile.

What is the difference between absolute and relative file paths?

An absolute file path starts from the root directory and specifies the complete path, whereas a relative file path is specified from the current directory without starting from the root.

How do you navigate to a parent directory in the Linux shell?

To navigate to a parent directory, you can use the '..' command. This moves you one directory level up in the file system.

What command is used to list files in a directory?

The 'ls' command is used to list files and directories in the current directory.

How can you display the content of a text file in the shell?

You can use the 'cat' command to display the content of a text file in the shell. For example, 'cat filename.txt' will show the content of 'filename.txt'.

What is the purpose of the 'mv' command in the Linux shell?

The 'mv' command is used to move or rename files and directories. You specify the source and destination to move a file from one location to another.

How can you avoid typing long file paths repeatedly in the shell?

You can use the Tab key for autocompletion in the shell. This helps complete commands and file paths automatically, saving time and reducing typing errors.
