Bad Unit Test

All of these produce duplicated output:

temp
result = execCmd('npx for-each-file -debug=full -glob=test/test/**/*.txt -cmd="echo <file>"')
npx for-each-file -debug=full -glob=test/test/**/*.txt -cmd="echo <file>"
node src/bin/for-each-file.js -debug=full -glob=test/test/**/*.txt -cmd="echo <file>"
