我想检查是否在今天创建了一个目录。如果确实如此，则将其上载到hdfs上，但如果dierectory的修改日期不同，则输出为已在hdfs上复制的目录。

# !/bin/sh

export DATA_PATH=/data/1/sanket

# We will enter the directory where we want to check other directories

cd $DATA_PATH

# Details of directories will be transfered into no_of_files.txt

ls -lh $DATA_PATH/ >> temp/no_of_files.txt

# We will extract name of the file from above file.

nameoffile=$(awk '{print $9}' temp/no_of_files.txt)

# Now we want today's date.

echo $(date) >> temp/date.txt

# So the modifying date and todays date will be copied to a variable.

filedate=$(awk '{print $6 $7}' temp/no_of_files.txt)
todaydate=$(awk '{print $2 $3}' temp/date.txt)

export "nameoffile"
export "filedate"
export "todaydate"

rm -fr $DATA_PATH/temp/no_of_files.txt
rm -fr $DATA_PATH/temp/name_of_files.txt
rm -fr $DATA_PATH/temp/date.txt

# Directory on HDFS where we want to copy data

path=sanket_data

# First to check that modifying date of directory and today's date to match and if so

# then copy the data on HDFS, if they dont match then give error as file already copied.

if [[ "$filedate" == "$todaydate" ]]; then
for filename in $nameoffile; do
    #path=sanket_data
    #nameoffile=$(awk '{print $9}' temp/no_of_files.txt)
    #for filename in $nameoffile
    /usr/bin/hadoop fs -put $DATA_PATH/$filename /user/sanket/$path
    #echo $filename already copied!
    done
elif [[ "$filedate" != "$todaydate" ]]; then

    #/usr/bin/hadoop fs -put $DATA_PATH/$filename /user/sanket/$path
    echo $filename already copied!
    #hdfs dfs -put $filename /user/sanket/$path
fi
