自动定时在每猛砸执行的命令和show提示？ [英] Automatically timing every executed command and show in Bash prompt?

问题描述

我经常会发生忘记明确preFIX处决时间命令，最好我会在接下来的外壳看到提示多少实时的最后一个命令了（在每个命令）。

I often happen to forget to explicitly prefix executions with the "time" command, ideally I would see in the next shell prompt how much real time the last command took (on every command).

我已通过的bash文档冲刷，但找不到相关的任何东西。

I already scoured through the bash documentation, but couldn't find anything related.

推荐答案

您可以这样做：

$ bind '"\C-j": "\C-atime \C-m"'

或者把这个在你的〜/ .inputrc文件：

"\C-j": "\C-atime \C-m"

然后当你想要做的睡眠时间1 您可以输入睡眠1 和preSS <大骨节病>控制 + <大骨节病>Ĵ而不是<大骨节病>输入。

Then when you want to do time sleep 1 you'd type sleep 1 and press Ctrl+J instead of Enter.

我不建议在bind命令调换Ĵ和 M （或在.inputrc文件文件） 。每次你preSS <大骨节病>输入你会得到时间添加这可能是pretty恼人的，并会导致错误打字时多行命令。

I would not recommend swapping the j and m in the bind command (or in the .inputrc file). Every time you'd press Enter you'd get time added which could be pretty annoying and would cause errors when typing a multi-line command.

您可以添加到您的〜/ .bashrc中来使时间更紧凑的输出：

You could add this to your ~/.bashrc to make the output of time more compact:

export TIMEFORMAT='r: %R, u: %U, s: %S'
