Metadata Extraction Tool

There seems to be an bug in the format of linux start scrips:

When I try to start extract.sh :

bash: ./metadata.sh: /bin/sh^M: bad interpreter: No such file or directory

After converting the shell scrips with the following utility I was able to
start them:

dos2unix extract.sh
dos2unix metadata.sh

If the file has been edited on a Windows machine it can sometimes Add CR/LF
(VM) characters on the end of each line, so #!/bin/sh becomes #!/bin/shVM
and as the ctrl-v/ctrl-m characters are special, and hidden by default on
most editors, it can create a really hard to find problem. To remove the
extra CR characters that UNIXish machines don't like, simply use the
dos2unix command:

* []dos2unix <infile> <outfile>

If your OS doesn't have dos2unix, then you can use:

* []cat <infile> | tr -d ``\r'' > <outfile>
