INTRODUCTION TO UNIX ==================== LAB #3 Create a directory called "lab3". Change to this directoy and do all the work here. 1. Run the following command in the background. sleep 300 Find the process id (pid) of this command. Use "kill" command to terminate this process. 2. Create a file called "abc" with a few lines of text in it. type the command: cat abc abc2 This should output the contents of the of the file "abc" and generate an error message. Change the above command to output including error message to a file "abc.out1". Send the output to a file called "abc.out.2" and errors to the file "abc.err.2". 3. There is an option to the "cat" command that will number each line that is output from a file. Find this option and use it to create a file called "n2" that contains the same information as "abc", but has each line numbered. Use "abc" as input. 4. How would you view all the processes currently running on the system. 5. how would you output just the second line from the file you created in #2. 6. Run the following command.... sleep 300 suspend this command. Look at the output from the "jobs" command. Use the "bg" command to change the "sleep" command from "stopped" to "running". Look at the output from the "jobs" command. Use "kill %1" to terminate the sleep command.
