File Processing Commands Worksheet

· What UID and PID have the highest amount of physical memory a process has used and is not swapped out? Show all processes and full output.

· If using a long listing and no process modifiers, what is the swap space amount for the bash command?

· When using top command, what command would you use to kill a process?

· If you were not using top command, what command would you use to kill a process?

· What command would you use to manually mount the standard CD-ROM device /dev/db1 at /media/disk?

· What command would you use to display the amount of available disk space on /dev/db1 in a human readable form?

· Type in the command grep – – help to access the help manual. Using this information and the information from the text, how would you write a command to find the pattern 111 in a file called myfile.txt?

 

TIPS/HINTS:

– Provide code and screenshot for each question,

– I often get the swap space for the full system as answer to #2.

– Once you get to “What command would you use to manually mount the standard CD-ROM device /dev/db1 at /media/disk?” you do not have to execute the commands. As a matter of fact, you’ll have trouble getting them to execute in the virtual environment.

– For output, I want to see a screen print or copy/paste of the actual output, not some descriptive text like “executed properly”. Without the output, I have no way of knowing if your commands actually worked correctly. This applies to all assignments in this class!
