小脚本方便编译执行golang

# 编译并执行当前目录下的简单golang程序, 之后清理可执行文件
# example:
# $ g hello.go
# or
# $ g hello
g() {
	PARAM=$1
	filename_without_extension=${PARAM%.go*}
	# echo $filename_without_extension

	if [ -f "$filename_without_extension.go" ]
	then
 		/usr/local/go/bin/go build "$filename_without_extension.go"; 

 		# 有报错时不会输出可执行文件
 		if [ -f "$filename_without_extension" ]
 		then
			/bin/ls -alFh ./"$filename_without_extension"
			./"$filename_without_extension";
			rm ./"$filename_without_extension";
 		fi
	else
 		echo "当前目录没找到: $filename_without_extension.go"
	fi
}
