[SOLVED] Terminal emulator & GRUB coloring

[anon222]

Perhaps we could change some colors

Code:

leafpad $HOME/.bashrc

Them adding this to the end

Code:

if [ $USER = 'root' ]; then
    PS1="\[\033[01;31m\]$USER@$HOSTNAME\[\033[0;00m\] \[\033[01;32m\]\w\\$\[\033[0;00m\] "
else
    PS1="\[\033[01;33m\]$USER@$HOSTNAME\[\033[0;00m\] \[\033[01;32m\]\w\\$\[\033[0;00m\] "
fi

Perhaps white bold would better match the current theme

Code:

if [ $USER = 'root' ]; then
    #If user is root just print the hostname in yellow
    PS1="\[\033[01;33m\]$HOSTNAME\[\033[0;00m\] \[\033[01;32m\]\w\\$\[\033[0;00m\] "
else
    PS1="\[\033[01;97m\]$USER@$HOSTNAME\[\033[0;00m\] \[\033[01;32m\]\w\\$\[\033[0;00m\] "
fi

Misko, that is a great idea. Having root as either bold or a different color just makes sense.

I like that idea too, Misko.

I'm surprised people have not been doing this within their profiles.  I've had my terminal colors and PS1 set for years across distros.

Great idea, Misko, especially considering newcomers to Linux would be a bit overwhelmed in having to figure that out.

I have configured it myself. BUT I definitely would prefer it coming out of the box this way.

In addition to this and even more important for me would be to implement that broken links are shown in a different color like this:


The last couple of days I have extensively worked with softlinks and it was a huge hassle with the default setting not showing valid and broken links in different colors.

Thanks, riser, for sharing!

Misko, that is a great idea. Having root as either bold or a different color just makes sense.

It's logical.

I like that idea too, Misko.

I think it would be helpfull. Some other distros use this by default.

I'm surprised people have not been doing this within their profiles.  I've had my terminal colors and PS1 set for years across distros.

LL-user everything is customizable. Those who remember DOS would easily adapt.
I think those os us who use the terminal more often would like to have some colors.
Those who don't probably think it's too geeky.
Thanks for your suggestion. We'll see about that.

I'm just using the default color settings. So the setup only needs one step, i.e. putting the following code into /etc/bash.bashrc:

Code:

if [ -f $HOME/.dir_colors ]; then
  eval $(/usr/bin/dircolors -b $HOME/.dir_colors)
elif [ -f /etc/DIR_COLORS ]; then
  eval $(/usr/bin/dircolors -b /etc/DIR_COLORS)
else
  eval $(/usr/bin/dircolors -b)
fi

[anon222]

I like that. No need for the eval here though.

Code:

if [ -f $HOME/.dir_colors ]; then
  /usr/bin/dircolors -b $HOME/.dir_colors
elif [ -f /etc/DIR_COLORS ]; then
  /usr/bin/dircolors -b /etc/DIR_COLORS
else
  /usr/bin/dircolors -b
fi

Have started working on LL 2.6, here is what I have for the root prompt, with a caution:

Hi Jerry,

Good idea to give an additional heads up.

I just did a test installation of Fedora and very much like their approach, a one time, extended warning at the beginning:
