List all files created today:
To list all files created today using the shell, you can use the find command with the -type f option to search for files only and the -ctime 0 option to search for files created within the last 24 hours.
Here’s the command you can use:
find /path/to/directory -type f -ctime 0
Replace /path/to/directory with the path to the directory where you want to search for files. If you want to search for files in the current directory, you can use . instead of the path.
This command will list all files that were created within the last 24 hours in the specified directory.
