Now I get it. Paper backup of data that one can later type in with less likelihood of error, with an expansion ratio nearly as good as the usual 3:4 of base 64.

BTW you can do the same thing with any Appimage.

For example Spacebear's Webcord(discord electron).

i have decided that these commands are a bad idea. the do work. but minor mistakes in usage can lead to many problems. they can be used in scripts OK, but so can mkdir. the big problem is mistyping the directory name. it will do as you say, not as you want. the mistyped name is likely to not exist. but it will be created, anyway, and your moved object will disappear from you, only to show up when you discover the directory with the funny name.

it is nice to be able to test if the directory is actually there. but mv can already do that with the -t option in front of the directory name.
