1. Create a single command to read a file called program.c and write a file called unreadable.c, by replacing all newlines and tabs with spaces, and replacing all multiple consecutive spaces with a single space. The result should still be a legal C program but not exactly readable.

2. Write a single shell command line, possibly consisting of multiple commands (separated by semicolons), that will create a file diffs.txt containing a list of all files found in my Documents directory that aren’t also found in yours. Assume your current working directory is your home directory.
