问题
I would like to call different other scripts, depending on whether a paramter is given or not:
"paramtest": "if [ -z $1 ]; then echo Foo $1; else echo Bar; fi",
npm run paramtest
should give "Bar".
npm run paramtest -- whatever
should give "Foo whatever".
However in practice I only get: (The parameter is added to the whole line, not 'passed in')
> if [ -z $1 ]; then echo Foo; else echo Bar; fi "whatever
sh: 1: Syntax error: word unexpected
What can I do better?
Essentially I am after running full test suite / only individual test with the same command...
"test" : "if [ -z $1 ]; then mocha ./test/**/*.test.js; else mocha $1
