For moving 6 months files from a hdfs location to another we can use the below script.

script should be run from your local linux location.

#!/bin/bash
hdfs dfs -ls /hive/warehouse/data.db/all_history/ |awk 'BEGIN{ SIXMON=60*60*24*180; "date +%s" | getline NOW } { cmd="date -d'\''"$6" "$7"'\'' +%s"; cmd | getline WHEN; DIFF=NOW-SIXMON; if(WHEN > DIFF){print $8}}' >> TempFile.txt
cat TempFile.txt |while read line
do
   echo $i
   hdfs dfs -cp -p $line /user/can_anns/all_history_copy/;
done

Line 2 : We are copying list of files which are of max 180 days to a TempFile. Then we iterate through this Temp file and if match is found then copy the file.

If you are writing the script from windows and copying to linux machine, sometimes it may not work showing syntax error. For avoiding the carriage return error, after copying the script to linux machine local path run the below command. sed -i 's/\r//' Then run the script >>> sh FileName.sh
