To list files by modification time using the ls command in Linux, you can use the -t option along with the command. The -t option causes the files to be sorted by modification time, with the most recently modified files listed first. Here is an example command:
ls -lt
This will display a list of all files in the current directory, sorted by modification time with the most recently modified files listed first. If you want to display additional details about the files, you can also use the -l option along with -t. For example:
ls -ltl
This will display a detailed list of all files in the current directory, sorted by modification time with the most recently modified files listed first. The detailed list will include information such as file permissions, owners, groups, and timestamps.
