UNIX命令行中类似Matlab的命令历史记录检索 [英] Matlab-like command history retrieval in unix command line

问题描述

在Matlab中，有一个我非常喜欢的功能.假设我键入了命令very-long-command，然后输入了几个命令.然后，如果以后再次需要长命令，只需键入very并按向上箭头键，我的长命令就会出现.它找到以very开头的最后一条命令.我无法在UNIX命令行中执行相同的操作，当我尝试执行此操作时，它会忽略我键入的内容，并按时间顺序返回到最后一个命令.有办法吗?

In Matlab, there is a very nice feature that I like. Suppose I typed the command very-long-command and then a few several commands afterwards. Then later if I need the long command again, I just type very and press the up arrow key, my long command appears. It finds the last command that starts with very. I couldn't do the same in unix command line, when I try to do it, it disregards whatever I typed, and goes back to the last commands in chronological order. Is there a way to do it?

推荐答案

在bash中，点击 ctrl - r 可以进行历史搜索:

In bash, hitting ctrl-r will let you do a history search:

$ echo 'something very long'
something very long
$ # blah
$ # many commands later...
(reverse-i-search)`ec': echo 'something very long'

在上面的代码段中，我在# many commands later...之后的下一行中击 ctrl - r ，然后键入 e c ，这使我回到了echo命令.此时，按 Enter 将执行命令.

In the above snippet, I hit ctrl-r on the next line after # many commands later..., and then typed ec which brought me back to the echo command. At that point hitting Enter will execute the command.
