Things to do after installing Linux

Change the default editor

$ sudo update-alternatives --config editor
There are 3 choices for the alternative editor (providing /usr/bin/editor).

  Selection    Path               Priority   Status
------------------------------------------------------------
* 0            /bin/nano           40        auto mode
  1            /bin/ed            -100       manual mode
  2            /bin/nano           40        manual mode
  3            /usr/bin/vim.tiny   15        manual mode

Press <enter> to keep the current choice[*], or type selection number: 3
update-alternatives: using /usr/bin/vim.tiny to provide /usr/bin/editor (editor) in manual mode

To avoid this needing to type password for sudo, you can edit /etc/sudoers and add this command at the end of the file:

$ sudo visudo

Note if you want to change the default editor use

$ sudo update-alternatives --config editor

Use the safe command sudo visudo to edit and check the syntax of the edits, otherwise if you directly edit and make a mistake you computer might not work.

%admin ALL=(ALL) NOPASSWD: ALL

Save and exit. Finally, you will also need to create the admin group:

groupadd admin

and again, you need to be part of the admin group. So type this command in a shell:

# usermod -a -G admin <your username>

You should be able to use sudo without password.

To increase timeout for sudo

Defaults timestamp_timeout=1800   # increase the sudo timeout

sudo vi /etc/fstab

  [ -x /usr/bin/id ] || return
# Jeff remove user filter for root
#  ID=`/usr/bin/id -u`
#  [ -n "$ID" -a "$ID" -le 100 ] && return
  # for bash and zsh, only if no alias is already set
  alias vi >/dev/null 2>&1 || alias vi=vim

Change ll to include directory by editing /etc/profile.d/colorls.sh

#when USER_LS_COLORS defined do not override user LS_COLORS, but use them.
if [ -z "$USER_LS_COLORS" ]; then

  alias ll='ls -aFl' 2>/dev/null

and

unset TMP COLORS INCLUDE

alias ll='ls -aFl --color=auto' 2>/dev/null
