shell 工具函数

 平时管理 linux 系统，一遍又一遍重复命令，太枯燥了。于是自己封装了一些好用的函数。

不想直接修改 /etc/bash.bashrc 文件，于是通过 source 引入我自定义的 bashrc.sh 文件。

$vim  /etc/bash.bashrc

# 最后加上引用文件

source /e/develop/shell/bashrc.sh#!/bin/bash

#!/bin/bash

#环境变量
programs=/usr/local
php=$programs/php
zookeeper=$programs/zookeeper
redis=$programs/redis
JAVA_HOME=$programs/java8


PATH=$PATH:$JAVA_HOME/bin:$php/bin:$zookeeper/bin:$redis/bin

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

alias dir-mod="sudo chmod -R"
alias reload="source /etc/bash.bashrc"
alias command-list="compgen -ac"

### 解压文件 ###
alias tar-programs="sudo tar -C $programs -xvf"

### 切换目录 ###
alias cd-programs="cd /usr/local"
alias cd-download="cd ~/Downloads"

alias search="apt search"
alias install='sudo apt install -y'
alias upgrade='sudo apt upgrade -y'
alias purge='sudo apt-get purge'
alias update="command 'sudo apt update && apt list --upgradable'"
alias autoclean="command 'sudo apt-get autoremove && sudo apt-get autoclean'"


#解压到 Downloads 目录，并删除压缩包，切换到Downloads 目录
function tar-download(){

    local file="$1"
    
    cd ~/Downloads  ＆＆ ／
    tar -C ~/Downloads -xvf $file && /
    trash ./$file && /
}

#写入日志
function log(){
    local file="$1"
    local text="$2"
    if [ -n "$text" ]; then
        text=$file
        file='debug'
    fi
    echo -e "$text" >> /tmp/"$file.log";
}

function red(){ echo -e "33[31m$133[0m";}
function green(){ echo -e "33[32m$133[0m";}

function command(){
    local command="$1";local param1="$2"; local param2="$3"
    red ">> $command $param1 $param2"
    eval $command $param1 $param2
}

# 打印参数列表
function args(){

    local index=1
    for arg in $@; do
        echo "arg${index}: '$arg'"
        let index+=1
    done

}
