I am trying to set
exec-shield protection on Linux as described here but getting the following error on Ubuntu Linux server version 12.04 LTS:
sysctl -w kernel.exec-shield=1
error: “kernel.exec-shield” is an unknown key

I recently switched from OS X to Ubuntu. When I run the ‘vim file.c’ command at terminal, I see an error message that read as follows:
The program ‘vim’ can be found in the following packages:
* vim
* vim-gnome
* vim-tiny
* vim-athena
* vim-gtk
* vim-nox
Try: apt-get install <selected package>
How do I fix this problem and why vim is not a default text editor on Ubuntu Linux? How can I install full-fledged vim text editor in Ubuntu Linux?

I am a new Unix / Linux user. I am using
whatis command to find man pages. But, I noticed that some man pages have a common names. For example, when I run
whatis printf:
Outputs:
printf (1) - format and print data
printf (1p) - write formatted output
printf (3) - formatted output conversion
printf (3p) - print formatted output
printf [builtins] (1) - bash built-in commands, see bash(1)
How do I access overlapping man pages and what is the meaning of (1), (1p), (3), and so on?
