The difference between “like” and “such as” is subtle, and they are often used interchangeably in informal English. But if you are writing technical material, such as a résumé of a set of complicated instructions, it pays to use the correct expression.
“Like” means “similar to, but not exact.”
“Such as” means “here’s an actual example.”
If you want to give your readers a general idea from which they can derive a pattern, use “like.” For example, you could write “…vehicular transportation like a dune buggy. Something that can handle rough terrain.”
But if you need to refer to something specific, use “such as.” So you might write “…you need a real truck, such as a Chevy S-10.” (An S-10 is a real truck, right?)
Don’t say “I write explanations like step-by-step instructions.” Do you write instructions or don’t you? If you do, use “such as.” With a comma after the “as.”
