Harmonizing the bash startup scripts

[lmello]

I noticed certain things about Salix (the coloring scheme in the boot sequence, for example) that I'd learned from Darrell Anderson's Slackware guide. The most useful part is, IMHO, the part about bash startup scripts and how you can 'harmonize' your shell environment. Why not include a similar set of scripts in /etc/skel for the next Salix release?

I added a few useful statements from Debian to make these:

Code: Select all

# /etc/bashrc
#
#####################################################################
#
# Basic bash startup files explanation:
#
# /etc/profile    ==> System-wide initialization file containing 
#                     global/system environment variables and 
#                     startup programs
#
# /etc/bashrc     ==> System-wide aliases and functions, and some 
#                     modifications to /etc/profile (to help 
#                     maintain /etc/profile as original as possible)
#
# ~/.bash_profile ==> Local/Personal environment variables and 
#                     startup programs called only during login
#
# ~/.bashrc       ==> Anything local/personal and peculiar to the 
#                     user
#
# Login command programmatically sources /etc/profile and then ONLY
# ~/.bash_profile OR ~/.bash_login OR ~/.profile, in that search 
# order
#
# Logout command programmatically sources ~/.bash_logout
#
# Non-login consoles such as xterm/konsole programmatically sources 
# ~/.bashrc
#
# /etc/bashrc is not sourced programmatically and must be sourced 
# manually
#
# Local setup: 
#
# ~/.bash_profile sources ~./bashrc and executes bash_login
# ~/.bashrc sources /etc/bashrc
# ~/.bash_logout executes bash_logout
#

# Needed to get "man" to work properly in Unicode locales:

# Evaluate terminal size and dynamically resize screen

# Don't put duplicate lines in the history:

fi

# Source /usr/local/bin/bash_login

	/usr/local/bin/bash_login

# --- Local/Personal startup programs ---

Code: Select all

# ~/.bash_logout
#
# see /etc/bashrc for a complete description how all bash source files
# are related and used on this box

# Source /usr/local/bin/bash_logout
if [ -x /usr/local/bin/bash_logout ]; then
	/usr/local/bin/bash_logout

Small things that make the difference - colorized grep output, vim and most as default pager and editor, all very well commented to make life easier for the terminal newbie

Nice

Seems a good idea. I will test them at home.
In fact I already use something like this, but not written as general/good as this.

When using the /etc/bashrc template provided above I get a message regarding the file /etc/profile.d/bash_completion.sh that doesn't exist. I just commented out the offending line.

W-What, you don't have bash-completion from /extra? That's a serious offence!

[maximus]

Yep, that was it! Cheers

You can grab my configuration files directly from here.

Well, should I apply for a ticket in the bugtracker?

These lines:
. /etc/profile.d/bash_completion.sh
. /etc/profile.d/coreutils-dircolors.sh
need a check if file exists.

And for non vim experienced users probably nano or mcedit is a much simpler to use editor.

EDIT: I'd also prefer the more standard looking PS1='\u@\h:\W\$ '

EDIT2: SuSE uses a red root prompt. Done by this:

Code: Select all

        # Colored root prompt (see bugzilla #144620)
        if test "$UID" -eq 0 -a -t ; then
            _bred="$(path tput bold 2> /dev/null; path tput setaf 1 2> /dev/null)"
            _sgr0="$(path tput sgr0 2> /dev/null)"
            PS1="\[$_bred\]$PS1\[$_sgr0\]"
            unset _bred _sgr0
        fi
