Must be completed by November 30th, 2010.
Fix/Complete The script below, sample webpage at http://tinyurl.com/23jgwtu
# Your script will be used to organize a collection of MP3 files.
# Files to be processed are expected to reside in a single directory
# (no sub-directories).
…
# Your script, must create subdirectories for each artist and
# create symbolic links to each song in appropriate directories.
# The script usage will be as follows:
# momo source_directory [destination directory]
# If the destination directory is not provided, the present working directory
# is the destination.
# The name of the file/link will be based on album and song name
# in the following format: Album – SongTitle.mp3
# Additional information:
# – All song metadata will be based on information in ID3v1 tags
# – Assume that all .mp3 files in the source directory have a valid ID3v1 tag
# (ID3v1 details can be found on-line: http://en.wikipedia.org/wiki/ID3#ID3v1)
# – .mp3 extensions can have any combination of upper- and lower-case letters
# – Assume that you have read permission for the source directory
# and write permission for destination
# – Ignore files in the source directory that do not have the .mp3 extension
# – Display an error message and exit with status 1 if no parameters are given
# – Display an error message and exit with status 2 if source is not a directory
# – Display an error message and exit with status 3 if destination
# does not exist or is not a directory
# In addition to creating a directory/file structure, your script must create
# a valid XHTML report file containing the output of the tree command,
# showing the above structure. The report will also show a footer section
# showing the source directory path, date/time when report was created
# and number of artist and songs organized.
# Your script will produce a single line of output to the shell
# (other than possible error messages), containing two numbers, separated by
# a single space: number of artists processed and number of songs processed.
### TO DO: Check if at least one parameter is supplied, exit on error
if [ $# ]
then
exit
fi
### TO DO: Check if first parameter is a directory, exit on error
# Set the destination to default (pwd) if no destination is provided
if [ $# -lt 2 ]
then
set “$1” .

### TO DO: Check if destination exists and is a directory, exit on error
