Given that your shell history size is large enough, you may retrieve the
/path/to/some/directoryby reverse search Ctrl+r.
This is quicker and cleaner the overwriting existing Julia’s directory. For installed packages, ~/.julia/ with automatically take care of them. For instance, you have v1.0 and v1.1 in ~/.julia/compiled.
In practice, Pkg> st and Pkg> update in the new version will take care of everything.
