Dollar sign get removed from process.argv on transpilation

process.argv script argument dollar sign $

Expected Behavior

Keep $ in process.argv when it correctly passed to script argument.

Actual Behavior

When creating a script that takes arguments, and if an argument is passed with a $, it disappear from it in process.argv.

Steps to reproduce the problem

1. Create a script that logs process.argv
2. Run the script with an argument containing a $

Minimal reproduction

dollar.ts:

console.log(process.argv);

execution (in bash terminal):

> npx ts-node ./scripts/dollar.ts --test='$7test'
[
  '/Users/me/project/scripts/node_modules/.bin/ts-node',
  '/Users/me/project/scripts/dollar.ts',
  '--test=test' // <---  '$7' disappeared
]

In pure JS, there is no issue with the same script:

> node ./scripts/dollar.js --test='$7test'
[
  '/Users/me/project/scripts/node_modules/.bin/ts-node',
  '/Users/me/project/scripts/dollar.ts',
  '--test=$7test' // <--- all good !
]

Converted to discussion because this is probably not a ts-node issue. We've received a ton of issues that are caused by all the moving parts outside of ts-node's control, for example: npm, npx, the shim script that is created by npm / npx, your shell, etc. If you're using 3 things at once, then you don't really know which one is causing the problem.

@cspotcode Thanks I didn't think about npx side effect.
I just tried and you are right, it is him causing the issue:

node_modules/.bin/ts-node dollar.ts --test='$123'
[
  '/Users/olivier/Projects/Sagacify/dollar/node_modules/.bin/ts-node',
  '/Users/olivier/Projects/Sagacify/dollar/dollar.ts',
  '--test=$123'. // $ still there
]

But with npx:

❯ npx ts-node dollar.ts --test='$123'
[
  '/Users/olivier/Projects/Sagacify/dollar/node_modules/.bin/ts-node',
  '/Users/olivier/Projects/Sagacify/dollar/dollar.ts',
  '--test=23' // $1 disappeared
]
