Why use $HOME over ~ (tilde) in a shell script?
Tilde expansion doesn’t work in some situations, like in the middle of strings like /foo/bar:~/baz

Of course, never fails. Found the solution about a minute after posting the above question… solution for those that may have had the same issue: ContextWrapper.getFilesDir() Found here.
~ is a bash-ism rather than a perl-ism, which is why it’s not working. Given that you seem to be on a UNIX-type system, probably the easiest solution is to use the $HOME environment variable, such as: if ( -e $ENV{“HOME”} . “/foo.txt” ) { print “yes ,it exists!” ; } And yes, I know …
I think os.path.expanduser(path) could be helpful. On Unix and Windows, return the argument with an initial component of ~ or ~user replaced by that user‘s home directory. On Unix, an initial ~ is replaced by the environment variable HOME if it is set; otherwise the current user’s home directory is looked up in the password …
I’ve run something like this in the past. LDAP is your best bet for centralized accounts. This is reasonably standard, and should be easy to set up. The client is merely a matter of installing a few packages (ldap-utils, libnss-ldap, and libpam-ldap), and editing /etc/pam.d/common-(everything). You’ll need to add a line like <type of file …
SSH can’t do that because SSH protocol does not include the requested hostname in the call. (HTTP is one of the few protocols that does include the requested hostname, which is how it can be used for virtual hosting.) There are a couple of other things you might try instead: You could create separate users …
It’s a Bash feature called “tilde expansion“. It’s a function of the shell, not the OS. You’ll get different behavior with csh, for example. To answer your question about where the information comes from: your home directory comes from the variable $HOME (no matter what you store there), while other user’s homes are retrieved real-time …
Since go 1.12 the recommended way is: package main import ( “os” “fmt” “log” ) func main() { dirname, err := os.UserHomeDir() if err != nil { log.Fatal( err ) } fmt.Println( dirname ) } Old recommendation: In go 1.0.3 ( probably earlier, too ) the following works: package main import ( “os/user” “fmt” “log” …
Is there something special with that directory or are you really just asking how to copy directories? Copy recursively via CLI: cp -R <sourcedir> <destdir> If you’re only seeing the files under the sourcedir being copied (instead of sourcedir as well), that’s happening because you kept the trailing slash for sourcedir: cp -R <sourcedir>/ <destdir> …
For individual folders (My Docyuments, My Pictures, etc., the “Special Folders”) I do the registry/GPO thing you alluded to. However, if I want to move the entire folder structure I cheat. Move the folder to a new location, and then create a junction pointing the old folder to the new folder. So all your programs …
