Mario you boss! :-D

Real thumbs up!

YES! Thank you!

tanks

Thanks, bro!

why not use the /etc/skel/.bashrc file?

Thanks!
Came here for this:
PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '

Thank you, I don't know why the hell Cubuntu have replaced this one with their crap bashrc file!!

Thanx... my profile is back in shape :D

indeed. just use that

Thanks you

You're awesome. Thanks.

This is excellent. Thanks!

Thank you !!

Thank you! I'm sure I did what most of the others above me did...I overwrote my .bashrc file (yes, I'm a noob). I'm not great at keyboarding. Thanks for the helpful copy and paste ease you provided.

Thank you!

Can you provide a source for this? Of course it is good nonetheless, but it would be good to have some other place to find similar things (such as official Ubuntu repository). Gist is somehow unofficial.

How can replace this file? Actually i have done some changes in bashrc file and due to I'm not able to edit it can anyone suggest me

Have you tried going in through terminal and trying sudo nano .bashrc?
have you checked the owner/permissions of the file? ls -al
if you are not the owner, or the permissions are not "-rw-r--r-- (your UN) (Your UN)"
To fix permissions: sudo chmod 644 .bashrc ?
To fix the Owner: sudo chown (Your UN) .bashrc

if none of that works... perhaps delete it and make a new .bashrc file? (Not sure how well that would or wouldn't work) But it is probably a permissions issue. Hopefully you can get it worked out.

BTW, Mario, thank you for posting this, very helpful.

thanx !!

why is the color of the username and computer name white??? Please answer my question:)

AsidikAlJr, if you'd like to change colors.. take a look at EZprompt

Thank you a lot!

your system already contains a copy of .bashrc file. if you want use that just run cp /etc/skel/.bashrc ~/

THERE is an error in line 53 let me correct please

Thanks a lot!
Needed some of this for a Mac :P

Thanks a lot.
But it displays the following message every time that i open new terminal:

alias alert='notify-send --urgency=low -i "$([ $? = 0 ] && echo terminal || echo error)" "$(history|tail -n1|sed -e '''s/^\s*[0-9]+\s*//;s/[;&|]\s*alert$//''')"'

alias egrep='egrep --color=auto'
alias fgrep='fgrep --color=auto'
alias grep='grep --color=auto'
alias l='ls -CF'
alias la='ls -A'
alias ll='ls -alF'
alias ls='ls color=auto'

Does any one of you faced this?

Thanks, I accidentally deleted my whole /home

Thanks a lot

nice thank you

Thank you!

oh that's a life saver
