In relation to this
node I'd like to point out that these one-liners aren't always the ones that I use to accomplish a task. For example there are several head(1)
variations. However, I never use these, I always use the system commands instead.
In addition it doesn't contain all of the one-liners that I ever use. There are many of the variety "print all lines greater than 72 characters" or "print the third field of every line" that I can easily reproduce and which I don't have to record.
Instead this list contains some longer one-liners that I might not remember, such as the module version one, and a lot of quirky variations that might be useful in golf or elsewhere. As such it serves me more as a sketchbook of ideas for future work than as a completed reference.
