+########## A ###########
+When you press [TAB], readline reads what you typed and sends it to bash for completion.
+Bash has inbuild function for add auto-completion results. So, Bash searches through those which are stored already for the give command. If it can't find a complete entry, it returns all the files in the current directory. We can also add entries to the completion.
+
+########## B ###########
+Relevant File for memory is '\proc\meminfo'
+
+The command we used to get the desired output : `cat meminfo | grep Mem | tr -d [:blank:] | cut -d ':' -f2`
+
+########## C ###########
+The command used to SSH to mars is `ssh {user-name}@mars.cse.iitb.ac.in`
+
+This command contains the '-X' argument where X represents X-server `ssh -X {user-name}@mars.cse.iitb.ac.in`
+After logging into mars server, to open -> `subl /tmp/lab03_inlab_C3.txt`
+
+We've done the password less authentication.
+
+########## D ###########
+
+We made an infinite loop (infiniteLoop.sh) 
+Command to run it in background is `chmod a+x infiniteLoop.sh` and `./infiniteLoop.sh &`
+
+To kill 'cell.sh', we used `kill -9 {process-id}`
+For process-id, we grepped through process using `ps aux | grep cell.sh`

+Reflection Essay :
+BASH - Bourne Again SHell
+We explored many aspects of BASH. We got an insight of how to search, edit, replace, delete with different
+ parameters. It was exciting to send POST requests, host server, tranfer files across machines. And, 
+also, ppm (Portable Pixmap) was uncompressed and inefficient. It was fun to crack zip file (kind of 
+brute force) passwords (:P).
+
+References : 
+Mostly Man Pages
+And The Linux Documentation Project Docs
+And Stackoverflow.
