The purpose of this script is to change the name of files/directories with spaces in the name to have a dash(-). So if a file/directory were named "A B", the new name would be A-B. The script will work on a directory specified on the command line and replace the spaces in the names for all files/directories underneath that directory.

Modify the script below following instructions in the script.

The options to the script are as follows:

-f the -f says to only rename files

-d the -d says to only rename directories

Both -d and and -f may be specifed.

the name of the directory that you will be processing.

For example:

Given the following

$ ls C D/ dirs.tar fix-spaces*

And the directory "C D" contained the following structure

./C D ./C D/E F ./C D/E F/G H ./C D/E F/G H/J K ./C D/E F/G H/J K/a b ./C D/E F/G H/a b ./C D/E F/a b ./C D/a b

After the script was run,

fix-space -f -d "C D"

the directory structure would be as follows:

C-D C-D/E-F C-D/E-F/G-H C-D/E-F/G-H/a-b C-D/E-F/G-H/J----K C-D/E-F/G-H/J----K/a-b C-D/E-F/a-b C-D/a-b
