9. Find out what shell I am using on Ubuntu
Please note that $SHELL is the shell for the current user but not necessarily the shell that is running at the moment. Try the following examples: (base) ashish@ashish-Lenovo-ideapad-130-15IKB:~$ echo $SHELL /bin/bash (base) ashish@ashish-Lenovo-ideapad-130-15IKB:~$ sh $ echo $SHELL /bin/bash $ ps -p $$ PID TTY TIME CMD 24437 pts/1 00:00:00 sh $Errors You Will Notice When Some of The Commonly Known Shells Are Not Available on Your System

Use the ps command with -p {pid} option. The following command selects the processes whose process ID numbers appear in pid. Use the following command to find out which shell you are in: $ ps -p $$ $ ps -p $$ PID TTY TIME CMD 24437 pts/1 00:00:00 sh $10. Getting Your RAM Information
