Introduction
The following is how I personally setup my Linux server.
When I first connect to a server, the first three things I do are setup vimrc, bash_profile, and screenrc (after installing screen, of course).
Why?
- vimrc: lets me understand and edit scripts better
- bash_profile: to make my bash console look better
- screenrc: lets my screen-using experience more satisfying
1. My ~/.vimrc looks as follows:
You can just copy and paste the text below.
Note that it's better to paste the text in after putting in the :paste command,
else you'll have to deal with deleting a shit lot of comment deleting and reformatting afterwards.
set nocp
" Vim5 and later versions support syntax highlighting. Uncommenting the next
" line enables syntax highlighting by default.
if has("syntax")
syntax on
endif
" ts=4 sts=4 sw=4 si et ai smarttab
" Customizing tabs
set shiftwidth=4 softtabstop=4 tabstop=4
set si et ai
" Press space to clear search highlighting and any message already displayed.
set hlsearch
nnoremap <silent> <Space> :silent noh<Bar>echo<CR>
" Change default DarkBlue comment_color to LightBlue
hi Comment ctermfg=LightBlue

2. My ~/.bash_profile looks as follows:
You can just copy and paste the text below.
Note again that it's better to paste the text in after putting in the :paste command,
else you'll have to deal with deleting a shit lot of comment deleting and reformatting afterwards.
# .bashrc
# Source global definitions
if [ -f /etc/bashrc ]; then
. /etc/bashrc
fi
# are we an interactive shell?
if [ "$PS1" ]; then
if [ -z "$PROMPT_COMMAND" ]; then
case $TERM in

if [ -e /etc/sysconfig/bash-prompt-xterm ]; then
PROMPT_COMMAND=/etc/sysconfig/bash-prompt-xterm

[ "$PS1" = "\\s-\\v\\\$ " ] && PS1="[\u@\h \W]\\$ "
# You might want to have e.g. tty in prompt (e.g. more virtual machines)
# and console windows
# If you want to do so, just add e.g.
# if [ "$PS1" ]; then
# PS1="[\u@\h:\l \W]\\$ "
# fi
# to your custom modification shell script in /etc/profile.d/ directory
fi
if ! shopt -q login_shell ; then # We're not a login shell
# Need to redefine pathmunge, it get's undefined at the end of /etc/profile
pathmunge () {
case ":${PATH}:" in
*:"$1":*)

*)
if [ "$2" = "after" ] ; then
PATH=$PATH:$1
else
PATH=$1:$PATH

# By default, we want umask to get set. This sets it for non-login shell.
# Current threshold for system reserved uid/gids is 200

3. My ~/.screenrc looks as follows (got it from a post made by Christian Wills - [email protected]):
You can just copy and paste the text below.
Note that it's better to paste the text in after putting in the :paste command,
else you'll have to deal with deleting a shit lot of comment deleting and reformatting afterwards.
# GNU Screen - main configuration file
# All other .screenrc files will source this file to inherit settings.
# Author: Christian Wills - [email protected]
# Allow bold colors - necessary for some reason
attrcolor b ".I"
# Tell screen how to set colors. AB = background, AF=foreground
termcapinfo xterm 'Co#256:AB=\E[48;5;%dm:AF=\E[38;5;%dm'
# Enables use of shift-PgUp and shift-PgDn
termcapinfo xterm|xterms|xs|rxvt ti@:te@
# Erase background with current bg color
# defbce "on"
# Enable 256 color term
term xterm-256color
# Cache 30000 lines for scroll back
defscrollback 30000
# New mail notification
# backtick 101 30 15 $HOME/bin/mailstatus.sh
hardstatus alwayslastline
# Very nice tabbed colored hardstatus line
hardstatus string '%{= Kd} %{= Kd}%-w%{= Kr}[%{= KW}%n %t%{= Kr}]%{= Kd}%+w %-= %{KG} %H%{KW}|%{KY}%101`%{KW}|%D %M %d %Y%{= Kc} %C%A%{-}'
# change command character from ctrl-a to ctrl-b (emacs users may want this)
#escape ^Bb
# Hide hardstatus: ctrl-a f
bind f eval "hardstatus ignore"
# Show hardstatus: ctrl-a F
bind F eval "hardstatus alwayslastline"
A quick linux console peek after editing the screenrc and opening up a screen session (to start a new session I put inscreen -R some_screen_name; to open a previous session I put in screen -x some_screen_name):
Since my server's language was configured as ko_KR.UTF-8, the weekday and month are shown in korean (토: Saturday, 월: Month)
Hope this helps! 😸
