bash 中函数的多个名称/别名

Question

是否可以为同一个 bash 函数设置多个别名，而不必跨多个别名重新定义函数的内容？

Answer 1

您只需要为它定义别名，而不是在同一个函数体中声明多个函数：

# attach a bash shell to a running docker container
function dexb {
    docker exec -it "" /bin/bash
}

# attach a sh shell to a running docker container
function dexs {
    docker exec -it "" /sh
}

# Now instead of creating another function say 'dex' with the same 
# content as the function 'dexb'

# I'll just create an alias

alias 'dex'='dexb'
