Xxd Command Not Found May 2026

Use find or whereis:

whereis xxd
# or
find /usr -name xxd 2>/dev/null

On macOS with Homebrew, xxd is often in /usr/local/bin/xxd or /opt/homebrew/bin/xxd (Apple Silicon). Add that directory to your PATH:

export PATH=$PATH:/opt/homebrew/bin

To make permanent, add that line to your ~/.bashrc or ~/.zshrc. xxd command not found

After following the platform-specific steps, run these simple tests:

# 1. Check if the binary exists
type xxd
On Debian-based systems (e.g., Ubuntu):
sudo apt-get update
sudo apt-get install vim-common

On Red Hat-based systems (e.g., CentOS):
sudo yum install vim-common

On macOS (with Homebrew):
brew install vim

sudo port install xxd

If you already have Vim installed via Homebrew (brew install vim), xxd should already be present.
Sometimes a fresh session solves path issues. Use find or whereis : whereis xxd #
