Pull request overview

This PR completes the bash_basics assignment by adding the “create an empty file from user input” exercise implementation and including placeholder files used in the parallel/merge workflow portion of the assignment.

Changes:

• Added a prompt/read flow to capture a filename and create the file in 01-read_input.sh.
• Added empty placeholder files (test.txt, parallel.txt) likely used for the branching/merge exercises.

read filename should use read -r to avoid backslash escape processing, and touch $filename should quote the variable (and preferably use --) to prevent word-splitting/globbing and option-like filenames (e.g., a name starting with -) being misinterpreted.

[Copilot]

Using touch will not necessarily "create an empty file" if the file already exists (it will just update timestamps). If the exercise requires guaranteeing an empty file, add an existence check and/or truncate the file explicitly (while handling the risk of overwriting).

Suggested change

	touch $filename
	echo "Your file $filename was successfully created in the parallel universe!"
	if [ -e "$filename" ]; then
	echo "Warning: $filename already exists and will be emptied."
	fi
	: > "$filename"
	echo "Your empty file $filename was successfully created in the parallel universe!"
