別名

Question

我想能夠設置內的別名做這樣的事情：

> function gitb(){ git checkout -b $1; alias $1='git checkout $1'; } 
> gitb sample 
Switched to a new branch 'sample' 
> git checkout master 
Switched to branch 'master' 
> sample 
Switched to branch 'sample' 

但是，功能gitb並不像預期的那樣，因爲：

> alias sample 
alias sample='git checkout $1' 

，而不是

> alias sample 
alias sample='git checkout sample' 

有誰能告訴我如何實現我想要的嗎？

Answer 1

瞭解單引號和雙引號之間的區別。

function gitb() { git checkout -b $1; alias $1="git checkout $1"; }
