CompTIA Linux+ XK0-006 (V8) Practice Question

You are writing a Bash wrapper script that must pass all of the positional parameters it receives on the command line to an underlying command without altering word boundaries.

Example wrapper invocation:

./deploy.sh "stage one" --tag=v1.2 *.rpm

Inside the script you currently have:

#!/bin/bash
deploy-tool "$PLACEHOLDER"

Which Bash special parameter expansion should replace PLACEHOLDER so that each original argument (including quoted strings and wild-card patterns) is preserved as its own separate word when deploy-tool executes?

  • "$*"

  • $#

  • $0

  • "$@"
