Cat Laser Pointer Neat Stuff To Buy Cat "some text here." > myfile.txt possible? such that the contents of myfile.txt would now be overwritten to: some text here. this doesn't work for me, but also doesn't throw any errors. specifically interested in a cat based solution (not vim vi emacs, etc.). all examples online show cat used in conjunction with file inputs, not raw text. How would it be possible in the example below to skip the step of writing to file "test.txt", i.e. assign the cat result to an object, and still achieve the same end result? i thought i'd include.
