Using the bourne shell /bin/sh write the utility called trash that satisfies the following specifications: Usage: trash -l | -p | { filename }* trash is a replacement for the rm utility. Rather than removing files, trash moves files into a subdirectory called .trash in your home directory. When there is a valid file to move, if .trash doesn't exist, it is created. if .trash exists, the -l option lists the current contents. if .trash exists, the -p option removes the directory and all files in it. Your script should handle any number of files.
