<>如何用shell脚本判断hive数据库是否导入dt分区的数据？
目标：将goals中所有的表名判断一遍，是否在hive的ods层中
tmp="part-" # 这里只取了"part-"这个字段 #遍历文本文件，获取表名称 for i in `cat /home/goals.txt` do
#获取hdfs上的以dt为时间分区的内容 temp1=`hadoop fs -ls /idp/src/ods/${i}/dt=$1`
#判断是否为空：这里用了grep来找出temp1字符串中是否有tmp("part-")这个子串 result=$(echo $temp1 | grep
"${temp0}") #创建每天执行任务的日志 cd /date touch $1.txt #判断是否有当日数据，都将结果输入创建的日志里 if [[
"$result" != "" ]] then echo "是" >> $1.txt else echo "否" >> $1.txt fi done
<>如何用python去除文件目录下所有文件的首行?
1.为何使用python去除？shell脚本同样能实现，看具体的需求，shell适合单个文件，python便于遍历整个文件夹。
2.如何使用删除首行功能？搭积木式，将搜索到的遍历功能和删除首行功能放在一起。
#conding=utf8 import fileinput import os # 获取目录下的全部文件 g = os.walk(r"/test") for
path,dir_list,file_list in g: for file_name in file_list: join = os.path.join(
path, file_name) #逐个删除文件的第一行 for line in fileinput.input(join, inplace=1): if
not fileinput.isfirstline(): print(line.replace('\n',''))
总结：我们在面对工作中编写程序的挑战，1.可以先试着完善功能，比如借鉴网络上其他人的实现方式。2.实现单个的测试，完成后再去做批量操作。3.最后再思考能否继续进一步优化。总之，我们采用小步快跑的方式完成开发挑战。
