I recently find it easier to bite the bullet and write the command on the spot, rather than to try to locate some custom made three liner somewhere. Just writing the logic from scratch becomes effortless with a bit of practice. It helps me focus on the task-at-hand, rather than digging into memory if I solved an issue before, and if I stored it somewhere convenient, with an apropriate name.

After having successfully located the snippet, only too often I have discovered that it does not do exactly what I want right now. Then I am left with the choice of changing the past script to also fit the new purpose, without destroying the previous work.

All this mental effort to save yourself three lines of typing seems a questionable endeavor. I have come to love the throwaway scripts.
