LinuxでPBCOPYおよびPBPASTEコマンドの使用方法

Since Linux and Mac OS X are Unix-based systems, many commands will work on both platforms. However, some commands are unique and might not be available on both platforms, for example pbcopy and pbpaste commands. These commands are exclusively available only on macOS platform.

Those who have switched from macOS to Linux might feel the absence of this command pair and would likely prefer to continue using them in Linux system. Worry not! If you've moved from macOS to Linux and are missing the pbcopy and pbpaste, I have a solution for you to bring similar functionality to Linux.

In this brief tutorial, I will explain how to replicate the functionalities of pbcopy and pbpaste and use Pbcopy and Pbpaste commands on a Linux system.

What are pbcopy and pbpaste Commands?

Pbcopy and Pbpaste are two command-line utilities on macOS that allow you to copy and paste text to and from the clipboard. They are similar to the familiar keyboard shortcuts ⌘+C and ⌘+V, but they can be used from within the terminal.

The pbcopy command will copy the standard input into clipboard. You can then paste the clipboard contents using pbpaste command wherever you want.

Here are some examples of how to use pbcopy and pbpaste:

Copy the text "Hello world!" to the clipboard:

pbcopy echo "Welcome to OSTechNix blog!"

Paste the contents of the clipboard into a new file:

pbpaste > mynewfile.txt

Copy the output of the command ls to the clipboard:

ls | pbcopy

While pbcopy and pbpaste are specifically available on macOS systems, there are a number of Linux alternatives to pbcopy and pbpaste, such as xclip and xsel.

Heads Up: The symbol ⌘, also known as the looped square, is the symbol for the command key on Apple keyboards.

What are xclip and xsel Commands?

Xclip is a command line interface to X selections i.e. Clipboard. Xclip reads the data from one or more files and makes the data available as an X selection for pasting the data into X applications.

Xsel is also a command line X11 selection and clipboard manipulation tool. It is used to access X clipboard and selection buffers in Linux and Unix-like operating systems.

For more details on xclip and xsel usage in Linux, please refer the following guide.

How To Access Clipboard Contents Using Xclip and Xsel In Linux

Using xclip or xsel programs, we can easily imitate the functionality of pbcopy and pbpaste commands in Linux.

Install xclip and xsel in Linux

Both xclip and xsel packages available in the default repositories of most Linux distributions. Please note that you don't have to install both utilities. Just install any one of the above utilities.

To install them on Arch Linux and its derivatives, run:

$ sudo pacman -S xclip xsel

On Fedora:

$ sudo dnf install xclip xsel

On Debian, Ubuntu, Linux Mint:

$ sudo apt install xclip xsel

Once installed, you need to create aliases for pbcopy and pbpaste commands.

Create Aliases for pbcopy and pbpaste

We can replicate the functionality of pbcopy and pbpaste commands using xclip and/or xsel commands via shell aliasing. Let us see how to do that!

1. Edit your ~/.bashrc file:

$ vi ~/.bashrc

2. If you want to use xclip, paste the following lines:

alias pbcopy='xclip -selection clipboard'
alias pbpaste='xclip -selection clipboard -o'

3. If you want to use xsel, paste the following lines in your ~/.bashrc file.

alias pbcopy='xsel --clipboard --input'
alias pbpaste='xsel --clipboard --output'

4. After adding the above lines, press ESC and :wq to save and close the file.

5. Next, run the following command to update the changes in ~/.bashrc file.

$ source ~/.bashrc

6. The ZSH users paste the above lines in ~/.zshrc file and update the changes using command:

$ source ~/.zshrc

Use Pbcopy and Pbpaste Commands on Linux

As mentioned already. the pbcopy command will copy the text from stdin into clipboard buffer. For example, have a look at the following example.

$ echo "Welcome To OSTechNix!" | pbcopy

The above command will copy the text "Welcome To OSTechNix" into clipboard. You can access this content later and paste them anywhere you want using pbpaste command like below.

$ echo `pbpaste`
Welcome To OSTechNix!

Here are some other use cases.

I have a file named file.txt with the following contents.

<strong>$ cat file.txt</strong> 
Welcome To OSTechNix!

You can directly copy the contents of a file into a clipboard as shown below.

$ pbcopy < file.txt

Now, the contents of the file is available in the clipboard as long as you updated it with another file's contents.

To retrieve the contents from clipboard, simply type:

<strong>$ pbpaste</strong> 
Welcome To OSTechNix!

You can also send the output of any Linux command to clip board using pipeline character. Have a look at the following example.

$ ps aux | pbcopy

Now, type "pbpaste" command at any time to display the output of "ps aux" command from the clipboard.

$ pbpaste

There is much more you can do with Pbcopy and Pbpaste commands. I hope you now got the basic idea about these commands.
