Proper method for addressing a user's home directory











up vote

I am making a dialog menu for an Ubuntu VPN that is calling up other scripts like this:



cd

cd myrepo/gui

./filetocall.sh


The first cd is to ensure the directory for the second cd is always home.



Is there a better method I can use to address this in one line? (Without specifically naming the user in the path, so it can be installed and used on a few devices?)






command-line bash home-directory

~ (tilde) or $HOME can be used for getting the current user's home directory, so you could do:



cd ~/myrepo/gui

cd "$HOME/myrepo/gui"


Or even execute it directly:



~/myrepo/gui/filetocall.sh

"$HOME"/myrepo/gui/filetocall.sh

    If filetocall.sh expects the CWD to be ~/myrepo/gui then executing it directly could cause issues. Doing the cd and the executable call in two steps would prevent that.

    @KevinJohnson That's true, though I would consider that to be a bug in filetocall.sh.

Use the same method used by login, which avoids being fooled by redefinitions of $HOME: 



homedir="$(getent passwd $( /usr/bin/id -u ) | cut -d: -f6)"

cd "$homedir"
