Mount .sparseimage from .bash_profile

I need to mount a .sparseimage from .bash_profile but I don't get how to do it. I tried:

alias of22='hdiutil attach "Documents/OF.sparseimage" -mountpoint "$HOME/OpenFOAM" > /dev/null ; . $HOME/OpenFOAM/OpenFOAM-2.2.0/etc/bashrc'

but this gives me:

hdiutil: attach failed - no mountable filesystem

if I double-click on it or I put it in Startup Items it works (but i need also to source the bashrc after the mount)

What's the problem?

Solution 1:

The open(1) command can do it:

/usr/bin/open /full/path/to/OF.sparseimage

Solution 2:

In fact, the command you use will mount the disk image, but there are two problems I see.

Before I get into those I want to clarify to all readers (as I had this problem), the following command will mount a disk image:

hdiutil attach image_name.sparseimage -mountpoint mount_point

where you specify image_name.sparseimage and mount_point to your liking.

Here are the problems with your specific case that I see:

1) You are not mounting it in the bash_profile. You are creating an alias. You must run the alias first to mount the disk image (with of22 in your case).

2) Seems like you've done #1 because you get the error message "no mountable filesystem". This is probably because the disk image is using a relative path, which means you must run of22 from the parent directory (which seems to be your home directory in this case).

Try changing the command to

hdiutil attach "$HOME/Documents/OF.sparseimage" -mountpoint "$HOME/OpenFOAM"

Notice the addition of "$HOME".
