Advanced Linux command line tricks can help you work faster and more efficiently. By learning a few simple commands, you can customize your environment, automate tasks, and even troubleshoot problems. The command line is a powerful tool, and learning how to use it can be a valuable skill.

1. Bash shell tricks

Bash shell tricks are a series of shortcuts and commands that help you work faster and more efficiently in a terminal window. Many of these tricks are specific to Bash, but some will work in other shells as well.

One of the most useful Bash shell tricks is tab completion. This allows you to type a partial command and then press the tab key to automatically complete the command. This can save a lot of time, especially if you are working with long commands or frequently used commands.

Another useful Bash shell trick is using aliases. Aliases are shortcuts for commands that you use often. For example, you could create an alias for the ‘ls’ command so that you could type ‘ll’ instead. This can save you a lot of time, especially if you use the same commands over and over again.

Bash shell tricks can be very helpful in increasing your productivity when working in a terminal window. If you are not familiar with Bash, there are many resources available online that can help you learn more about it. Once you start using Bash shell tricks, you may find that your workflow improves dramatically.

2. Zsh shell tricks

The Zsh shell is a powerful tool that can help users optimize their workflows. One of the ways it does this is by providing users with a number of shortcuts and tricks that can help speed up common tasks. For example, Zsh can be used to quickly create new directories without having to leave the command line. Additionally, Zsh can be used to automatically fill in long paths or commands that have been previously typed. This can be a huge time saver for users who often find themselves typing out long commands. Finally, Zsh provides users with the ability to customize their prompt, which can be a helpful way to remind oneself of what directory one is currently in.

3. Tmux tricks

Tmux is a terminal multiplexer, which allows you to run multiple terminal sessions within a single window. It is useful for managing your workflow and keeping track of multiple tasks.

There are a few tricks that can make using tmux more efficient. For example, you can use the prefix key (usually Ctrl-b) to quickly navigate between panes. You can also use the split-window command (prefix + “) to split your window into multiple panes. This can be useful for working on multiple tasks simultaneously.

Finally, tmux provides a number of keyboard shortcuts that can make your life easier. For a full list of shortcuts, type “prefix ?”. Some of the most useful shortcuts include “prefix c” (create a new window), “prefix n” (next window), and “prefix p” (previous window).

By using these tricks, you can make tmux an incredibly powerful tool for managing your workflow.

4. Vim tricks

Vim tricks are a series of modifications that can be made to the Vim text editor to make it more efficient and user-friendly. Many of these tricks center around making text editing faster and easier, as well as increasing the software’s overall compatibility with different types of files. One popular Vim trick is known as ‘substitute’, which allows users to quickly find and replace text within a document. Another is ‘folding’, which allows long documents to be easily navigated by folding them down to a more manageable size. Finally, the ‘auto-indent’ feature can be used to automatically indent new lines of text, saving time and effort when editing files.

5. Emacs tricks

Emacs is a text editor that is optimized for SEO. It is easy to use and has a lot of features that make it ideal for editing text. One of the best things about Emacs is that it is free and open source.

6. Git tricks

1. Git is a powerful tool that allows developers to manage their codebase and track changes easily.

2. One of the great things about Git is that it is optimized for search engine optimization (SEO). This means that when people search for code snippets or examples online, they are more likely to find results from Git repositories.

3. Another neat trick that Git offers is the ability to easily create and merge branches. This can be a huge time-saver for developers working on large projects with multiple team members.

7. Ssh tricks

If you’re looking for ways to optimize your Secure Shell (SSH) experience, look no further than these seven SSH tricks.

1. Use Different Ports

The first step is to use a different port than the default port 22. This will help to keep your SSH server more secure by making it harder for attackers to find. You can change the port by editing the /etc/ssh/sshd_config file and changing the Port directive.

2. Use Key-Based Authentication

Another way to make your SSH server more secure is to use key-based authentication instead of password authentication. This means that you will generate a public/private key pair and use the public key to authenticate with the server. The private key should be kept safe and should not be shared with anyone.

3. Disable Password Authentication

If you’re only going to use key-based authentication, you can disable password authentication altogether. This will make it impossible for anyone to login with a password, even if they have your private key. To do this, edit the /etc/ssh/sshd_config file and change the PasswordAuthentication directive to “no”.

4. Use a Strong Cipher

When connecting to an SSH server, you should use a strong cipher to encrypt the connection. A strong cipher is one that is not easily broken by attackers. The best way to choose a strong cipher is to use the highest priority cipher that both the client and server support.

5. Use a Strong MAC

In addition to using a strong cipher, you should also use a strong Message Authentication Code (MAC). A MAC is used to verify that the data being transmitted has not been tampered with. The best way to choose a strong MAC is to use the highest priority MAC that both the client and server support.

6. Use compression

Compressing the data being transmitted over an SSH connection can help to save bandwidth and improve performance. To enable compression, edit the /etc/ssh/sshd_config file and change the Compression directive to “yes”.

7. Use a Proxy Command

If you need to connect to an SSH server through a firewall or proxy, you can use a ProxyCommand. This will allow you to connect to the SSH server using another program, such as sshuttle or corkscrew.

8. Rsync tricks

Rsync is a powerful tool for keeping files in sync between two or more computers. It can be used to sync files on your local machine, or between two remote machines.

There are a few tricks that can be used to make rsync more efficient. One is to use the –compress option, which will compress the data before it is sent, and decompress it on the receiving end. This can save a lot of bandwidth, especially if you are syncing large files.

Another trick is to use the –checksum option. This will cause rsync to calculate a checksum for each file before it is transferred. If the checksum on the receiving end does not match, the file will be transferred again. This can be useful if you are syncing over a slow or unreliable connection.

Finally, you can use the –delete option to delete files on the receiving end that do not exist on the sending end. This can be useful if you want to keep your destination directory clean and tidy.

9. Curl tricks

Curl tricks can help improve your website’s SEO by making it more optimized for search engines. Curl tricks can be used to improve your website’s title, description, and keywords so that it appears higher in search results. Curl tricks can also be used to create backlinks to your website, which can improve your website’s ranking.

10. Wget tricks

1. Use wget to download all the files on a website
This can be done by using the -r (recursive) flag:

wget -r

2. Use wget to download a website for offline viewing
You can use wget to create a local copy of a website:

wget –mirror -p –convert-links -P /local/directory

3. Use wget to download a file from a password protected website
If you need to download a file from a password protected website, you can use the –user and –password flags:

wget –user=username –password=password
