Programming in C: Lesson 1, HW 1

Ran the program. Tried using a different escape character. Get the warning "unknown escape sequence"

# \o unknown escape sequence
~/code/c/kr/chap1 $ gcc helloworld.c

Learning Vim from the inside: Lesson 3, HW 2

Used the -R option of lid as shown in the code below:

   -R, --result=STYLE
          STYLE is one of `filenames', `grep', `edit' or `none'

Very nice output:

Learning Vim from the inside: Lesson 2, HW 1

Ran mkid from the vim dir so that I could query over all files in the codebase.

Thanks for introducing this. Had no idea about it. @dioltas thanks for examples.
