linux alias 命令別名並輸出其原始命令

alias 功能固然好用，但在快捷方便的同時，隱藏了原始命令的結節。久而久之，不記得原始命令是什么了，因些，我想到了實現原命令輸出，以作為提示。先看效果圖吧。

 

 

/etc/bash.bashrc 文件追加代碼如下：

#環境變量
PASSWORD=root
PROGRAM=/usr/local
PACKAGE=/e/package

PHP=$PROGRAM/php
ZOOKEEPER=$PROGRAM/zookeeper
REDIS=$PROGRAM/redis


PATH=$PATH:$PHP/bin:$ZOOKEEPER/bin:$REDIS/bin

#history 配置
export HISTSIZE=1000; HISTTIMEFORMAT='%F '; HISTCONTROL="ignoredups"
export HISTIGNORE="ls:ll:pwd:history"

alias reload="source /etc/bash.bashrc"
alias command-list="compgen -ac"
alias on="execute 'reboot'"
alias off="execute 'poweroff'"

### 切換目錄 ###

alias search="execute 'apt search'"
alias update="execute 'sudo apt update && apt list --upgradable'"
alias upgrade="execute 'sudo apt -y upgrade'"
alias dpkg-list="dpkg --list | grep"
alias remove="execute 'sudo apt -y --purge remove'"
alias autoremove="execute 'sudo apt autoremove && sudo apt autoclean'"
