Question
For each command give me the ENTIRE COMMAND SEQUENCE. If I ask you 'What command would I use to move the file one.txt to the parent directory and rename it to two.txt?", the answer is NOT 'mv'. That is only part of the command.
11. I just created the following shell script in the file "runme.sh": #!/bin/sh find / -type f -name *.tmp -size +10k -size -20k -exec rm {} ; I save the file attempt to run it, and received the error bash: ./runme.sh: Permission denied. Show me the command that solves the problem. (5 pts) 12. Create a command that will search for files under /etc that contain the keyword "PAM" and return a COUNT of the number of files found. That's all I want to see, a number which is a representation of the amount of files found - nothing else. (5 pts) 13. Create a command that will identify files under /usr/bin that are greater than 10 kilobytes and less than 900MB. (5 pts) 14. Create a command that will run the script runthis.sh 33 minutes from now. (5 pts) 15. I've run 24 commands in the background from a terminal. Some of these I know will take some time to complete. How would I find out what commands have not completed yet? (5 pts)
