Simple Bash script for Linux I made for processing and zipping submission material for COMP 4521 at HKUST

comp4521.sh

#!/bin/bash

if [[ $# -ne 2 ]]; then
  echo "Usage: /path/to/comp4521.sh prefix project"
  echo "Where:"
  echo "- prefix is the file to prepend to all JavaScript programs"
  echo "- project is the project directory to apply the action to"
  exit 1
fi

if [[ ! -f "$1" ]]; then
  echo "First argument must be the name of a valid file"
  exit 1
fi

if [[ ! -d "$2" ]]; then
  echo "Second argument must be the name of a valid directory"
  exit 1
fi

tmpdir="$(mktemp -d)"
cp -r "$2/." "$tmpdir/"

for file in $(find "$tmpdir" -name "*.js"); do
  tmpfile="$(mktemp)"
  cat "$1" "$file" > "$tmpfile"
  mv "$tmpfile" "$file"
done

cwd="$(pwd)"
cd "$tmpdir"
zip -rm "$cwd/$2" .
cd "$cwd"
rmdir "$tmpdir"
