Escape special shell characters when using os.Getenv

[weiten...@gmail.com]

I tried to `escape` dollar sign when using os.Getenv; 

I found that golang doesn’t do exactly what I expect (for example `$$var_one` —> print `$var_one`). 

Any suggestion?

my temporary solution requires copying code from golang os pkg https://play.golang.org/p/nnsK9llwvr

There is no escaping mechanism built in to os.Expand.

One workaround would be to define an environment variable containing a dollar sign: https://play.golang.org/p/InJx2_EWB2

Another is to substitute an unused character or string and replace it after expansion: https://play.golang.org/p/j8Oa3dgdoH
