I would like to run `echo $PATH` bash command, see the result and optionally capture it in a string or array of strings. I started with:

```julia
julia> run(`echo $PATH`)
ERROR: UndefVarError: PATH not defined
julia> run(`echo \$PATH`)
$PATH

```

which doesn’t work.

Probably this is what you are looking for?

```julia
julia> ENV["PATH"]

julia> my_variable = ENV["PATH"]

```

You need to invoke a shell that interprets the `$` for you:

```julia
run(`bash -c "echo \$PATH"`)

```
