+TaskA-
+	printf- for subtask 5
+	export -subtask 3
+	alias for subtask 4
+	bash uses regex search in readline library. The Readline library includes functions to maintain a list of previously-entered command lines, to recall and perhaps reedit those lines, and perform history expansion on previous commands.
+
+TaskB-
+The executable file is task2.sh
+We are using the following command-
+grep 'Mem' /proc/meminfo | tr -d " " | cut -d':' -f2
+
+TaskC-
+For ssh to mars account-
+	ssh kartiks@mars.cse.iitb.ac.in
+for subtask 3
+	ssh -p 22 -X kartiks@mars.cse.iitb.ac.in
+	subl /tmp/lab3_inlab_C3.txt
+for subtask 4
+	press enter when asked for "file in which to save the key"
+	press y if asked for overwrite
+	press enter when asked for passphrase both time
+	then enter your cse password and login by running the command : ssh <cse-username>@mars.cse.iitb.ac.in
+TaskD-
+Subtask 3
+	For running a script file in background just run the file by using command : ./<script-file-name>.sh & e.g. ./infiniteLoop.sh &
+	the & in last tells the shell to run the program in background. We figured it out by googling how to run a process in background and got answer at http://askubuntu.com/questions/562911/how-to-execute-a-task-in-background
+Subtask 4
+	for killing a background process command used is : pkill <process name> e.g. pkill infiniteLoop.sh
+	We figured this by searching pkill on google.
+Subtask 5
+	for killing cell.sh command used is : pkill -9 cell.sh
+	We figured this out firstly by searching what to do when ctrl+c don't work in ubuntu then we got the answer at http://superuser.com/questions/243460/what-to-do-when-ctrl-c-cant-kill-a-process then used pkill instead of kill to kill the process by its name.

+Reflection Essay-
+	1) learned to use grep,sed,cut,unzip,awk,ls,find,rm,cat,ncat,mv,echo commands in bash
+	2) learned to write while and for loops in bash script files. Also if and case statements.
+	3) It was an awesome task we enjoyed a lot doing the tasks, Cheers to the problem setters.
