command-line (positional) output selector
Sometimes it happens that I work with IDs from entity identifier lists. They have very long ids, there are many of them, but it’s possible to hash them easily with grep resulting a set of cca. 20 from which I can choose visually the one I’m really interested in, although don’t want to type the whole ID for the grep. I used to copy the particular identifier to the clipboard and paste it to the next command line. With this solution below I can explore these sets and work with them without copy-paste (which frequently involved touching the mouse and moving hands away from the keyboard).
