The pgrep command is used to find processes by various criteria, such as user name, group name, process ID, command name, etc. The -u option specifies the user name or user ID to match. Therefore, the command pgrep -u bob will show all processes owned by the user bob. The output will be a list of process IDs, one per line. To show more information about the processes, such as command name, arguments, state, etc., the -l, -a, and -f options can be used. For example, the command pgrep -l -u bob will show the process ID and the command name for each process owned by bob. References:

The cron job syntax consists of five fields that specify the time and date of execution, followed by the command or script to run. The fields are: minute, hour, day of month, month, and day of week. Each field can have a specific value, a range, a list, a wildcard (), or a step value. The wildcard () means any possible value for that field. The option B sets the minute field to 0 and the hour field to *, which means the script will run at the 0th minute of every hour, regardless of the day, month, or weekday. This is equivalent to once per hour. The other options are either invalid syntax or do not match the desired frequency. For example, option A sets all fields to *, which means the script will run every minute of every hour of every day, month, and weekday. Option C sets the minute field to * and the hour field to 0, which means the script will run every minute of the 0th hour, or once per day at midnight. Option D has a typo (o instead of *) and option E sets the day of month field to o, which is not a valid value. References:

The correct configuration line for sending all messages from the auth facility to a remote syslog server is auth.* @logger.example.org. In syslog configuration, the auth.* specifies the facility and priority, where auth is the facility for security/authorization messages, and * represents all priorities. The @ symbol is used to indicate that the messages are to be sent to a remote server, followed by the hostname of the remote syslog server. References:
