Homework1 write-up, as written by a fellow student in the class


1. After logging in, I made the directory, homework:
        % mkdir homework
2. To make the subdirectory homework1:
        % cd homework
        % mkdir homework1
3. To copy the file:
        % cd homework1
        % cp /tmp/eeb553/kunitz_inhibitors.fa .
4. To make an alternate copy, two_seqs.fa:
        % cp kunitz_inhibitors.fa two_seqs.fa
5. To edit two_seqs.fa:
        % pico two_seqs.fa
        -Here, I placed the curser on the first character of the first line
        and used ^K to cut all but the last two sequences. I used the ^x 
        function to quit, saving the file two-seqs.fa
6. To rename kunitz_inhibitors.fa:
        % mv kunitz_inhibitors.fa kun.fa
7. To count the number of sequences in kun.fa using grep and wc and to print the 
        results (the number of lines containing ">") to the file kunitz_count:
        % grep ">" kun.fa | wc -l > kunitz_count
