问题描述
在〜/ .bash_profile中定义了别名,例如。 alias vaguppro ='vagrant up --provision
In ~/.bash_profile aliases are defined, eg. alias vaguppro='vagrant up --provision
我想要的是的回声在终端中键入
。 vaguppro
后,请vagrant up --provision
What I want is an echo of vagrant up --provision
after typing vaguppro
in the terminal.
类似于when一种是在终端中键入 ls -hal
,然后再次键入!ls
。在执行之前,终端中会出现 ls -hal
的回声。
Similar to when one types ls -hal
in the terminal, then again type !ls
. There's an echo of ls -hal
in the terminal before execution.
某些解决方案
vaguppro='vagrant up --provision'
alias vaguppro='echo $vaguppro && $vaguppro'
或下面的andlrc函数解决方案。
or andlrc's function solution below.
推荐答案
您可能会发现此快捷方式很有用:
You may find this shortcut useful:
shell-expand-line (M-C-e)
Expand the line as the shell does. This performs alias and his‐
tory expansion as well as all of the shell word expansions. See
HISTORY EXPANSION below for a description of history expansion.
换句话说,如果您写 vaguppro
然后在bash的默认Emacs模式下按 + + ,它将在当前行中扩展别名并将其转换为浪费--provision
。然后,您可以按Enter键照常运行。
In other words, if you write vaguppro
and press ++ in bash' default Emacs mode, it will expand aliases in the current line and turn it into vagrant up --provision
. You can then press enter to run as usual.
