在两个Difiefrent变量中查找Unix文件的用户名(WHO更新)和最后更新的时间

Question

我有文件 file1.txt，我想知道谁以及何时在两个不同的变量中更新。也是在其他变量中创建的时间。我尝试了下面的命令，毫无目的

find /unix_work -mtime -1 -ls
find /unix_work -type f -mmin -2
grep -H /unix_work/file1.txt /home/*/.bash_history
stat file1.txt

Answer 1

我找到了一个解决方案：

birth_stat_file1=`stat file1.txt --format="%W"`
birth_stat_file2=`stat file2.txt --format="%W"`
FROM_EMAIL=[e-mail]
To_EMAIL=[e-mail]
while true
do
    last_change_stat_file1=`stat file1.txt --format="%Z"`  
    user_name_file1=`stat file1.txt --format="%U"`
    last_change_stat_file2=`stat file2.txt --format="%Z"`  
    user_name_file2=`stat file2.txt --format="%U"`
    if (( $last_change_stat_file1 > $birth_stat_file1 )); then
        echo "mail from here !!!!!!!!!!"
        echo "$user_name_file1 file has changed at $last_change_stat_file1..." | mailx -r $FROM_EMAIL -s "File1.txt has changed" $To_EMAIL
    fi
    if (( $last_change_stat_file2 > $birth_stat_file2 )); then
        echo "mail from here !!!!!!!!!!"
        echo "$user_name_file2 file has changed at $last_change_stat_file2..." | mailx -r $FROM_EMAIL -s "File2.txt has changed" $To_EMAIL
    fi
    birth_stat_file1=$last_change_stat_file1
    birth_stat_file2=$last_change_stat_file2
    sleep 30  #change time in seconds to fix hits
    echo "hit [CTRL+C] to stop this loop!"
done
