Linux - 如何把一个脚本注册为命令，成为系统的新命令

cd && mkdir -p cmd

cd ~/cmd
vim vlog

#!/bin/bash



# 判断参数是否非空
if [ -z "$1" ]
then
  echo 'Error Param , value 1 - 2'
  exit 1
fi

if [ $1 == 1 ]
then
	echo "我是1 "
elif [ $1 == 2 ]
then
	echo "我是2 "
fi


# 注册命令

# chmod +x ~/cmd/vlog.sh
# export PATH=~/cmd:$PATH

chmod +x ~/cmd/vlog
export PATH=~/cmd:$PATH
