You can use the 'at' command to schedule a job to run in the future (once), or use the 'crontab' command to schedule jobs to run periodically on a time and date basis. Look at the 'man' commands to see how the actual scheduling parameters are specified.
The basic 'who' command lets you see the time of last system boot; list of users logged-in; the current run level, etc.
There are several variants of the 'make' command, and you should use the 'man make' or 'info make' command to see what your platform is using. In general, the make command requires a makefile, sometimes a target, and can use optional variable parameters, such as: make -f myMake.mk which is the simple version of calling 'make'. The targets and dependencies of the myMake.mk are in that file. The complexities of using the 'make' command with targets, etc., is too complex to answer here.

Go to the Command prompt and run "help" command to see the command list..
Ironically, the command to see who is logged into the system is who. You can also see who is logged on using the wcommand.
The VOL - DOS command displays the disk volume label and serial number, if they exist. See the related link for more information.

That depends on what you want to know. If you want to know how much disk space is being used, use the df command. If you want to see what files systems are mounted, use the mountcommand. If you want to see SMART information about a particular drive, use smartctl.
