小技巧：

不用vim编辑文件：

~ cat > test.sh
echo "ENTER control+D to end editor"

使用control+D 结束编辑

 

随记

# 系统日志
cat /dev/null > /var/log/messages

# 当前用户UID
echo $UID
echo $SHELL  grep root /etc/passwd
# 当前用户
echo $USER
# 当前用户家目录
echo $HOME
# 当前目录
echo $PWD



# 使用vim代替vi
alias vi=vim

# 判断bash版本是否过旧，存在安全隐患
env x='() { :;}; echo be careful' bash -c "echo this is a test"

# 用户变量加载顺序
/etc/profile ~/.bash_profile ~/.bashrc /etc/bashrc

用户环境变量变量优先推荐 ~/.bashrc  ~/.bash_profile 

全局变量
/etc/bashrc 推荐
/etc/profile
/etc/profile.d/xxx.sh  登陆后即可显示c

登陆提示：
/etc/motd
或
/etc/profile.d/xxx.sh 


# 查看环境变量
set 显示全局变量 局部变量
env 显示全局变量
declare 全局变量 局部变量 函数 整数 
set -o 显示bash shell的所有参数配置信息

# 自定义环境变量的三种方式
export 变量名=value
变量名=value ;export 变量名
declare -x 变量名=value

declare 可定义变量的类型
unset 消除本地变量

# head,tail省略 -n参数
head -1 /etc/init.d/kafka
tail -3 aa.py
