golang学习的点点滴滴：flag包解析命令行参数

import(
	"fmt"
	"flag"
)

funcmain(){
	varin*string=flag.String("in","infile","inputinfile...")
	varout*string=flag.String("out","outfile","inputoutfile...")
	varop*string=flag.String("op","op..","ops...")

	//命令行使用xxx.exe-inthisisin-outthisisout-opthisisops
	flag.Parse()//解析

	ifnil!=in{
		fmt.Println("inFile:",*in,"outFile:",*out,"op:",*op)
	}
}
