正如其他人已经指出的，使用函数应被视为最佳实践。

然而，这里有另一种方法，利用xargs：

alias junk="xargs -I "{}" -- mv "{}" "~/.Trash" <<< "

注意，这会对流的重定向产生副作用。

这个问题被问错了。您不会创建一个接受参数的别名，因为别名只是为已经存在的对象添加第二个名称。OP想要的功能是创建新功能的功能命令。您不需要对函数进行别名，因为函数已经具有名称。

我想你想要这样的东西：

function trash() { mv "$@" ~/.Trash; }

就是这样！您可以使用参数$1、$2、$3等，或者只使用$@

完善上面的答案，您可以获得与别名类似的单行语法，这对于shell或.bashrc文件中的特殊定义更为方便：

bash$ myfunction() { mv "$1" "$1.bak" && cp -i "$2" "$1"; }

bash$ myfunction original.conf my.conf

不要忘记右右括号前的分号。同样，对于实际问题：

csh% alias junk="mv \\!* ~/.Trash"

bash$ junk() { mv "$@" ~/.Trash/; }

Or:

bash$ junk() { for item in "$@" ; do echo "Trashing: $item" ; mv "$item" ~/.Trash/; done; }

下面是我的~/.bashrc中的三个函数示例，它们本质上是接受参数的别名：

#Utility required by all below functions.

有一次我做了一些有趣的项目，我仍然在使用它。它显示了一些动画，而我通过cp命令复制文件，因为cp没有显示任何内容，这有点令人沮丧。所以我取了这个别名

alias cp="~/SCR/spiner cp"

这是spiner脚本

#!/bin/bash

#Set timer
T=$(date +%s)

#Add some color
. ~/SCR/color

#Animation sprites
sprite=( "(* )  ( *)" " (* )( *) " " ( *)(* ) " "( *)  (* )" "(* )  ( *)" )

#Print empty line and hide cursor
printf "\n${COF}"

#Exit function
function bye { printf "${CON}"; [ -e /proc/$pid ] && kill -9 $pid; exit; }; trap bye INT

#Run our command and get its pid
"$@" & pid=$!

#Waiting animation
i=0; while [ -e /proc/$pid ]; do sleep 0.1

    printf "\r${GRN}Please wait... ${YLW}${sprite[$i]}${DEF}"
    ((i++)); [[ $i = ${#sprite[@]} ]] && i=0

done

#Print time and exit
T=$(($(date +%s)-$T))
printf "\n\nTime taken: $(date -u -d @${T} +'%T')\n"

bye

看起来像这样

要具体回答有关创建别名以将文件移动到垃圾箱文件夹而不是删除文件的问题，请执行以下操作：

alias rm="mv "$1" -t ~/.Trash/"

当然，你必须先创建dir~/.Trash。

然后只需发出以下命令：

$rm <filename>
$rm <dirname>
