I use a bash script to install an app on Mac OS X Lion.

  • 0

I use a bash script to install an app on Mac OS X “Lion”. First I copy the app bundle into place, then attempt to install postgres into the app bundle. The data path for the postgres db needs to be in “~/Library/Application Support/myappfolder/data/”.

Now the problem (appears to be) that the script stumbles because the OS says the path is not found. Backing up the path names I get to “~/Library/” and it still fails. The script is run with admin privileges.

To put this another way, from the terminal, this works:

   me: cd ~/Library

but this does not:

   me: mydir="~/Library/"
   me: cd $mydir

I know things have changed in 10.7, but I haven’t found the answer at the dev center yet.

    I don’t think this is Lion-specific. When you use quote marks, you are causing the ~ character to be treated literally, instead of as an alias for $HOME. So it’s looking for an actual directory with a tilde in the name, which doesn’t exist.

    Try using mydir="$HOME/Library" instead to see if that fixes the problem.
