Fix stat file path to absolute file path

[zchee]

I as much as possible to follow to Linux (also GNU), I have installed coreutils with --with-default-names in Homebrew. Also, stat is shell built-in command of zsh.

If using the stat of coreutils or zsh,

# in zsh built-in stat,
stat: bad file descriptor

# in coreutils stat,
stat: cannot read file system information for ‘%u’: No such file or directory

that error will occur.

So, it was changed stat command path to an absolute path.

What do you think?

I'm fine with using the absolute paths on principle - though I tend to write a shell script with a specific (minimal) shell in mind. This script's shebang is /bin/sh. Do you have /bin/sh invoking zsh, or otherwise somehow run prepare_iso.sh via zsh normally?

@timsutton Oh, I missed. /bin/sh shebang was enabled.

set -x in script, and result,

This problem caused by stat command flag difference of OS X default and GNU coreutils. Not zsh. Sorry.

Thanks for clarifying - still a good idea to use absolute paths for UNIX utils that differ from GNU versions. Merging!
