Final answer:
None of the commands kill, bg, or fg are used for obtaining process information. The ps command is appropriate for process information, while kill, bg, and fg are used for process control.
Step-by-step explanation:
Process information in the current shell cannot be directly obtained by using kill, bg, or fg commands. These commands are used for process control: kill is used to send signals to a process, often to terminate it; bg resumes a suspended job in the background; and fg brings a job to the foreground. To obtain information about the processes, you can use the ps command or top command for real-time process monitoring.
