Modern Alternatives to Popular Linux Commands

Please be aware that these alternatives do not fully replace the widely-used traditional Linux commands. Instead, they serve as substitutions that offer comparable functionalities. Also some of the utilities given below are written in modern programming language (E.g. Rust).

Now let us discuss about 17 modern replacements for the legacy Linux commands.

1. Bat: Alternative to cat Command

Bat is a modern replacement for the traditional cat command. It offers syntax highlighting, line numbers, and Git integration for code review.

Install autojump in Linux:

$ sudo apt install autojump # For Ubuntu/Debian$ sudo dnf install autojump # For Fedora

To use autojump, you need to configure you shell to source /usr/share/autojump/autojump.sh on startup.

If you use Bash, add the following line to your ~/.bashrc (for non-login interactive shells) and your ~/.bash_profile (for login shells):

. /usr/share/autojump/autojump.sh

If you use Zsh, add the following line to your ~/.zshrc (for all interactive shells):

. /usr/share/autojump/autojump.sh

autojump Usage:

Please note that directories must be visited first before they can be jumped to.

j <partial_directory_name></partial_directory_name>

Example:

To quickly jump into the directory named pyapps, run:

$ j pya

Project Link: Autojump GitHub Repository

4. zoxide: Alternative to cd Command

zoxide is a command line directory navigation tool that remembers your frequently used directories. It allows you to quickly "jump" to these directories using minimal keystrokes. It's compatible with all major shells.

Install zoxide in Linux:

The recommended way to install zoxide is by using the following one-liner script:

$ curl -sS https://raw.githubusercontent.com/ajeetdsouza/zoxide/main/install.sh | bash

zoxide is also available in the default repositories of many popular Linux distributions, so you can install it using your distribution's default package manager.

$ sudo apt install zoxide # For Ubuntu/Debian 
$ sudo dnf install zoxide # For Fedora

To start using zoxide, you'll need to integrate it into your shell's configuration.

For the Bash shell, edit ~/.bashrc file and add the following line to the end:

eval "$(zoxide init bash)"

For Fish shell, edit ~/.config/fish/config.fish file and add the following line at the end:

zoxide init fish | source

For Zsh, add this to the end of ~/.zshrc file:

eval "$(zoxide init zsh)"

zoxide Usage:

z <partial_directory_name></partial_directory_name>

7. sd: Alternative to sed Command

sd is a modern version of sed that focuses on simplicity and ease of use. It allows for easy find-and-replace operations.

Install sd in Linux:

Make sure you have installed Rust on your system and use the cargo package manager to install sd like below:

$ cargo install sd

sd Usage:

sd 'pattern_to_replace' 'replacement' filename

• 'pattern_to_replace': The text you want to replace.
• 'replacement': The text you want to replace the pattern with.
• filename: The name of the file you want to perform the replacement on.

Example:

Here's a practical example of how you can use the sd command for find-and-replace operations on a text file:

Let's say you have a text file named example.txt with the following content:

Hello, this is an example text file.
It contains some sample text that we'll use for sd command demonstration.

You want to replace all occurrences of the word "example" with "illustrative". Here's how you can achieve this using the sd command:

$ sd 'example' 'illustrative' example.txt

In this example, the sd command searches for the pattern "example" and replaces it with "illustrative" in the example.txt file.

After running this command, the contents of example.txt will be modified to:

Hello, this is an illustrative text file.
It contains some sample text that we'll use for demonstration.

8. jq: Alternative to awk Command

jq is a command-line JSON processor that allows you to extract and manipulate data from JSON files.

Install jq in Linux:

$ sudo apt install jq # For Ubuntu/Debian$ sudo dnf install jq # For Fedora

The syntax of the jq command is as follows:

jq 'filter_expression' filename

• 'filter_expression': The filter expression that specifies the data you want to extract or manipulate from the JSON.
• filename: The name of the JSON file you want to process.

Example:

Here's a practical example of how you can use the jq command to manipulate JSON data:

Let's say you have a JSON file named data.json with the following content:

{
  "name": "Senthil Kumar",
  "age": 40,
  "email": "senthil@kumar.com",
  "address": {
    "street": "123 Main St",
    "city": "Namakkal",
    "country": "India"
  },
  "hobbies": ["reading", "traveling", "coding", "writing"]
}

You want to extract the value of the "email" field from this JSON data. Here's how you can achieve this using the jq command:

$ jq '.email' data.json

After running this command, you'll get the following output:

"senthil@kumar.com"

In this example, the .email argument passed to the jq command tells it to extract the value of the "email" field from the JSON data.

You can use jq to perform various operations on JSON data, such as filtering, mapping, aggregation, and more. It's a powerful tool for working with JSON in the command line.
