取消删除在bash删除命令 [英] undelete the deleted command in bash

问题描述

如果你写了一个很长的命令，说 CD /非常/长/路径，然后你做的Ctrl + C或Ctrl + U键（如果游标在结束），然后你意识到你想要的命令后面，有没有什么办法让全线回，而无需重新输入。有没有什么绝招来改变的.bashrc 让的.bash_history 跟踪键pressed在外壳上，而不是刚过进入被击中。

If you have written a really long command, say cd /very/long/path, and then you do ctrl+c or ctrl+u (if the cursor is at the end), and then you realise that you want the command back, is there any way to get the full line back without re-typing. Is there any trick to change .bashrc so that bash_history keep track of keys pressed on the shell and not just after the enter is hit.
