Solution

The correct command sequence to accomplish this task is:

find /path/to/logs -type f -name "*.log" -mtime +7 -exec rm {} \;

Here's a step-by-step explanation:

  1. find /path/to/logs -type f -name "*.log": This command will find all files (-type f) with the extension .log in the directory /path/to/logs.

  2. -mtime +7: This option will filter out the files that were last modified more than 7 days ago.

  3. -exec rm {} \;: This option will execute the rm command on each file that matches the previous conditions. The {} is a placeholder for the current file, and \; indicates the end of the -exec command.

This command sequence is efficient because it only spawns one rm process per file, and it handles errors well because find will not pass non-existing files to rm.
