del files
not reversable
>del /p file.txt # delete file.txt with confirmation
>del /P *.txt # it will delete all files in current dir with confirmation. Omitting it might cause fatal damage.
command chaining (order matters)
below command will make dir and point to it.
>mkdir "hello world" && cd "hello world"
sequential execution
suppose there is not folder 
with the name aryan k. The second command will run regardless of first command execution.
>cd "aryan k" & echo "" > file.txt
# it will create file.txt in current folder
conditional execution
You can control your command if faliure.
>cd "hello" || echo "not exist" # incase of hello not exist it will print "not exist"
part two is coming
