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.

Re: [SOLVED] Terminal emulator & GRUB coloring - gold_finger - 05-04-2015

I like that idea too, Misko.

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!

It's logical.

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

LL-user everything is customizable. Those who remember DOS would easily adapt. Wink

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. Smile

Thanks for your suggestion. We'll see about that.

Re: [SOLVED] Terminal emulator & GRUB coloring - LL-user - 05-05-2015

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

Re: [SOLVED] Terminal emulator & GRUB coloring - anon222 - 05-05-2015

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:
