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>

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

alias junk="delay-arguments mv _ ~/.Trash"

延迟参数脚本：

# Example:
# > delay-arguments echo 1 _ 3 4 2
# 1 2 3 4
# > delay-arguments echo "| o n e" _ "| t h r e e" "| f o u r" "| t w o"
# | o n e | t w o | t h r e e | f o u r

RAW_ARGS_COUNT="$#"

for ARG in "$@"; do
  #echo $ARG
  if [[ "$ARG" == "$ARG_DELAY_MARKER" ]]; then
    SKIPPED_ARGS=$((SKIPPED_ARGS+1))
  fi
done

for ((I=0; I<$RAW_ARGS_COUNT-$SKIPPED_ARGS; I++)); do
  ARG="${RAW_ARGS[$I]}"
  if [[ "$ARG" == "$ARG_DELAY_MARKER" ]]; then

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>

函数和别名都可以使用其他函数和别名所示的参数。此外，我想指出几个其他方面：

1.函数在自己的作用域中运行，别名共享作用域

在需要隐藏或暴露某些内容的情况下，了解这种差异可能很有用。它还表明，函数是封装的更好选择。

function tfunc(){
    GlobalFromFunc="Global From Func" # Function set global variable by default
    local FromFunc="onetwothree from func" # Set a local variable

}

alias talias='local LocalFromAlias="Local from Alias";  GlobalFromAlias="Global From Alias" # Cant hide a variable with local here '
# Test variables set by tfunc
tfunc # call tfunc
echo $GlobalFromFunc # This is visible
echo $LocalFromFunc # This is not visible
# Test variables set by talias
# call talias
talias
echo $GlobalFromAlias # This is invisible
echo $LocalFromAlias # This variable is unset and unusable 

输出：

bash-3.2$     # Test variables set by tfunc
bash-3.2$     tfunc # call tfunc
bash-3.2$     echo $GlobalFromFunc # This is visible
Global From Func
bash-3.2$     echo $LocalFromFunc # This is not visible

bash-3.2$     # Test variables set by talias
bash-3.2$     # call talias
bash-3.2$     talias
bash: local: can only be used in a function
bash-3.2$     echo $GlobalFromAlias # This is invisible
Global From Alias
bash-3.2$ echo $LocalFromAlias # This variable is unset and unusable

2.包装脚本是更好的选择

在我身上发生过几次，当通过ssh登录或涉及切换用户名或多用户环境时，找不到别名或函数。源点文件有一些提示和技巧，或者这个有趣的别名：aliassd='sudo'让这个后续的别名aliasinstall='sd-apt-get-install'按预期工作（注意sd='udo'中的额外空间）。然而，在这种情况下，包装脚本比函数或别名更有效。包装器脚本的主要优点是它在预期路径（即/usr/loca/bin/）下是可见的/可执行的，其中作为函数/别名需要在其可用之前获取。例如，您将一个函数放在~/.bash_profile或~/.bahrc中用于bash，但稍后切换到另一个shell（即zsh），则该函数不再可见。因此，当您有疑问时，包装脚本始终是最可靠和可移植的解决方案。
