To check for new files in the /var/www/uploads/ directory on a Unix or Linux system, you can use the find command with the -newer option.
For example, to find files in the /var/www/uploads/ directory that were modified within the last 24 hours, you can use the following command:
find /var/www/uploads/ -type f -newerBt "-1 day"
This will search the /var/www/uploads/ directory for regular files (-type f) that were modified within the last 24 hours (-newerBt "-1 day"). The -B option specifies that the time comparison should be made using the file's modification time, and the -t option specifies the time threshold.
To find files that were modified within the last week, you can use the following command:
find /var/www/uploads/ -type f -newerBt "-1 week"
To find files that were modified within the last month, you can use the following command:
find /var/www/uploads/ -type f -newerBt "-1 month"
You can also use the -newerXY option to specify a reference file, which will be used as the basis for the time comparison.
For example, to find files in the /var/www/uploads/ directory that were modified after the file /reference/file, you can use the following command:
find /var/www/uploads/ -type f -newerXY /reference/file
This will search the /var/www/uploads/ directory for regular files that were modified after the file /reference/file.
Keep in mind that the find command is recursive by default, so it will search all subdirectories of the specified directory for files that meet the specified criteria.
