In reverse-i-search (Ctrl+R ) ,Any method to switch between similar commands in history
提问by Arun
I think an example will be good to understand my question.
我认为一个例子会很好地理解我的问题。
...
scp file1 [email protected]:/home/user1/linuxfiles/samplecode/important
...
...
scp file1 [email protected]:/home/user1/linuxfiles/samplecode/important/tested
...
...
Assume that is the order of commands in history. If I am doing Ctrl+Rand type scpit will show the last executed scpcommand ( ie the line ending with 'tested') .
假设这是历史命令的顺序。如果我正在执行Ctrl+R并键入scp，它将显示最后执行的scp命令（即以“tested”结尾的行）。
But I want to locate the scp command ending with 'important'. So is there any way in this reverse-i-searchto view all commands starting with scp, to choose the appropriate one?
但我想找到以“important”结尾的 scp 命令。那么有什么方法reverse-i-search可以查看所有以 scp 开头的命令，选择合适的命令吗？

Keep pressing Ctrl-Rand it will traverse your history.
继续按Ctrl-R它会遍历你的历史。

If your search terms are a bit more complicated/ not contiguous, another option is to grep among the historyresults, e.g.:
如果您的搜索词有点复杂/不连续，另一种选择是在history结果中使用grep ，例如：
history 300 | grep scp | grep important$
This will return a list of commands in your history that match, such as:
这将返回历史记录中匹配的命令列表，例如：
3323 scp file1 [email protected]:/home/user1/linuxfiles/samplecode/important
3325 scp file1 [email protected]:/home/user1/winfiles/samplecode/important
And you can then execute the relevant command with !3325.
然后您可以使用!3325.
I sometimes find this useful when running a lot of similar commands and may have to press Ctrl+Rmany times to get back to the exact command.
我有时会发现这在运行许多类似的命令时很有用，并且可能必须多次按Ctrl+R才能返回到确切的命令。

There is great alternative to Ctrl+R
有很好的替代品Ctrl+R

安装https://github.com/dvorka/hstr
run it with hh
运行它 hh
it shows a list of you all the last commands executed (contents of ./bash_history)
它显示了您最后执行的所有命令的列表（./bash_history 的内容）
if you start typing the list will be filtered based on what you type
如果您开始输入，列表将根据您输入的内容进行过滤
you can use Up/Downarrows to select the desired command and select it with Enter
您可以使用Up/Down箭头选择所需的命令并使用Enter
