I’ve been burnt before using ! and forgetting what command I typed previously, thus invoking the wrong command line.
!! is handy for the sudo example, but beyond that, I tend to prefer pressing the up arrow to cycle through the history rather than picking the first item. Eg:
!ssh
vs
ssh[up]
It’s the same number of key strokes but less error prone
- CoastalCoder 2mo agoAgreed. I especially cringed at the author's example of mixing that with "sudo".
- refp 2mo agothe "mixing of sudo"-example is using `!!`, which as explained is the immediately previous command, a little confused how that translates to the "execute command somewhere in the history" argument?
- CoastalCoder 2mo agoI suppose it depends on the kinds of mistakes to which one is prone.
- pcblues 2mo agoThat's mixing human memory with root access. Worse than AI :) I have lost more to mistakes than bugs over 30 years.
- refp 2mo agoWorth noting that `ssh[up]` isn't available by default in bash nor zsh — though it wouldn't surprise me if helpers such as oh-my-zsh enables it for you. `ssh[up]` is certainly an awesome feature — though (perhaps sadly) not default behavior. > I've been burnt before using ! and forgetting what command I typed previously If you want to make sure you do not execute commands you did not intend to, the section linked below is a great start: - https://refp.se/articles/your-shell-and-the-lazy-exclamation-mark#i-dont-trust-my-exclamation-mark-fu-just-yet-any-advice https://refp.se/articles/your-shell-and-the-lazy-exclamation... You may also look into `magic-space` which makes the expansion of event-designators happen inline, I thought about including it but the article felt long even without it. Thanks for reading the article, I hope it was a worthwhile read even with alternate workflows elsewhere!
- hnlmorg 2mo agoThanks for the tips. These days I don’t use sh derivatives as my primary shell and the shell I do use has a few features to make command search more ergonomic and safer. But these are useful tips nonetheless
