Check if file was created more than 10 minutes from now

Question

In my script i want to check if file named "Flag" was created more than 10 minutes from now, and if it was, delete it.

Got something like this:

ZMIENNA=`find /home/maciej/testy/ -mmin +10 -name Flag`
if [ -N $ZMIENNA ]
then
        rm /home/maciej/testy/Flag
fi

Thank you for replying.

Why do you use -N? This option test if the file "is modified since it was last read". Maybe you want to check if the string ZMIENNA is not empty? The is -n lowercase and add "" to protect the string ZMIENNA — terence hill, Nov 20 '15 at 09:09

You can just use find to delete a file, for example to delete file1 in the current folder:

find . -name file1 -mmin +10 -exec rm {} \;

According to the manual the option -mmin of find is based on the last modification date:

 -mmin n
        File's data was last modified n minutes ago.

As stated by this post : How to get file creation date/time in Bash/Debian? the creation time is not stored as file metadata on POSIX systems.
