Shell Scripting / Bash Tricks

Stop fighting overquoted command line arguments

🧩 The Challenge

You finally write a script that needs to pass a command with flags into an SSH session or a wrapper, but your carefully escaped quotes just vanish into the ether, leaving you with a broken mess. I’ve wasted an entire afternoon once trying to get a remote find command to execute correctly because Bash ate my backslashes.

💡 The Fix

Start using printf %q to escape your arguments perfectly before you hand them off to another command. It saves you from the nightmare of nested quoting rules that nobody actually memorizes.

my_args=$(printf "%q " "$@")
ssh remote_host "do_something $my_args"

⚙️ Why It Works

This utility generates a string that is properly escaped for shell input, which essentially means it wraps everything in the necessary quoting so the shell interprets the string as a single, literal argument rather than expanding it prematurely.

🚀 Pro-Tip: Always double-quote your variables, even when you think you’re being clever.
