Пробовал со скриптом «Ниже», тоже работало нормально
Пожалуйста, запустите скрипт после 12:00
#!/bin/bash
d=`date +%Y-%m-%d -d "1 days ago"`
#echo $d
echo "Below are list of files present"
find . -maxdepth 1 -type f -iname "*.txt" -newermt $d| sed "s/\.\///g"
count=`find . -maxdepth 1 -type f -iname "*.txt" -newermt $d| sed "s/\.\///g"| wc -l`
if [ $count -eq 9 ]
then
echo "Total Number of file exsists in present directory is $count"
zero_sizefile=`find . -maxdepth 1 -type f -iname "*.txt" -newermt $d -size 0| wc -l`
if [ $zero_sizefile > 0 ]
then
echo "Below are zero sized files"
find . -type f -iname "*.txt" -newermt $d -size 0
else
echo "No files are zero sized files"
fi
else
echo "All files doesnt exists"
fi
Вот так:
$ awk -F, 'NR==FNR {a[$5 FS $6]; next} ($1 FS $2) in a' file1 file2
