Perfect! I love regular syntax! For example, Lojban uses a method of saying phonemes to describe words, like Hebrew, so the number 100,508,290 is just an utterance rather than a sentence. panono k'io munobi k'io resono Rather than One hundred million, five hundred and eight thousand, two hundred and ninety. consistent, simple, fast, unambiguous. numbers are a common occurrence, so they should be fast to speak, So when the extremely common occurrence of me forgetting to include sudo for a command that requires escalated privileges, I expect that task made easier. As an alternative, think of it like this. the specific operation of "put the whole previous command in this place surrounded by new text" is actually a common idiom in calculation programs. Commonly called "ans". Mathmatica actually marks the results of all its computations with a tag (I think t[n]) so you can recall arbitrarily. That's not to say I'm a stick in the mud, if "sudo !!" sucks, make it better! How about something that turns a command into a postfix command? Or actually having a hotkey recall the previous command? Maybe a hotkey that looks at the text in the argument then searches up the history to replace? so if I type sudo rm^U it takes 'rm' and searches up history, replacing it with the first match, "sudo rm -rf ~/opt/java"? Lots of possibilities!
