Q) A command that is entered on the command line consisting of one process or a series of processes using a pipe is considered a 'token' and can me managed as one entity.

A) Answer is True.
Explanation:
1) When shell parses a command on the command line it breaks them into tokens and validates if they are the right commands being used.
2) The commands which are considered as tokens by shell will be verified if it is a valid internal or external command.
3) If it does not find command as internal or external it will throw "command not found" error.

Q) The previous lead job has the character:

A) Answer is "-".
Explanation:
1) The "+" sign next to a job number indicates current job which is nothing but last command stopped while it is running as foreground earlier.
2) The previous job is always marked as "-" sign.
3) In order to refer current job we can use "%" or "%+" and to indicate previous job it is represented as "%-"

Q) The following field contains the state of the process (when you run the ps -aux command). For example, S, R, or I (sleeping, running, idle)

A) Answer is "STAT".
Explanation:
1) The STAT column indicates the state of process.
2) The process state can be sleeping, running, Idle, interruptible sleep etc
