Using the boxes Command to Create ASCII Art Boxes on Unix/Linux

The boxes command is a text filter that can draw ASCII‑art frames around input text or code, useful for creating email signatures, comment blocks, or decorative output in scripts and editors.

Installation on Debian/Ubuntu can be done with the apt-get package manager: $ sudo apt-get install boxes Typical output shows the package being downloaded and installed, confirming the new boxes binary is ready for use.

Installation on RHEL/CentOS/Fedora requires enabling the EPEL repository and using yum: # yum install boxes The command displays dependency resolution, download size, and installation progress, ending with a “Complete!” message.

Installation on FreeBSD can be performed via the ports collection or the pkg_add utility:

cd /usr/ports/misc/boxes && make install clean

# pkg_add -r boxes

Once installed, basic usage is as simple as piping text through boxes: echo "This is a test" | boxes The -d option selects a specific design (e.g., boxes -d dog), while -l lists all available styles defined in /etc/boxes/boxes-config.

In vim or vi , the command can be invoked as an external filter. For example, positioning the cursor on a line and typing 3!!boxes will replace that line with the boxed version of its content.

Additional examples show how to embed the current date, wrap comment blocks in source files, and create elaborate ASCII art using predefined patterns.
