Your .bashrc file

Hey,

based on this reply from archer7 some topics ago, I thought it would be cool to share some .bashrc tips around!
As Bash is our always-there friend and we usually spend some good time on it, I think it is natural to tweak it a bit to have our personality.

For ones that might not have messed with it so far, .bashrc is a textfile generally located at your home directory which is run when you start a bash terminal.
And that is awesome, you can do great things with it.
For instance, you can set your PS1 variable there. The PS1 variable is the one responsible for setting the appearance of the command line's "line". Mine, for example, which is pretty standard, is:

Code:

[erico@hp ~]$ 

As archer7 pointed, you can put things there like only show the name of current directory instead of whole path to it, show the time/date... make it colored and these stuff.
This is a cool topic from Arch wiki which points some tips about customizing it. (The title talks about colors, but in fact it points tips in general and lists some options.) (This is Arch wiki but this will work on whatever distro.)

I also think this file is a good file to get started on dealing with Linux's file based customizing (skill which I'd call essential in Arch at least). It is simple, there are plenty tutorials around and you can see some visual results with it, at the same time you aren't breaking anything if you do something wrong.
There are many 'post your .bashrc' topics on forums around, just googleing something like 'bashrc tips' or 'your bashrc' gives some results.

So, here's mine:

Code:

# Check for an interactive session
[ -z "$PS1" ] && return

if [ -f /etc/bash_completion ]; then
	. /etc/bash_completion
fi

alias ls='ls --color=auto'
alias sl='ls'
alias ll='ls -la'
alias :q='exit'
alias :Q='exit'
alias :e='vim'
alias :s='locate'
alias exir='exit'
alias exti='exit'
alias xeit='exit'
alias xeti='exit'
alias exi='exit'

fortune
printf "\n"
PS1='[\u@\h \w]\$ '

Which is pretty simple, but does the job to me so far. I like the simple. The two first structures were pasted from somewhere...

As you can see, I do alot of typos and I don't like to read something like "exti: command not found". Also there are some vim aliases there for when I am somewhat sleepy coding and I don't want to spend time thinking whether i'm inside vim or outside it.

Oh, and in case you haven't used it, fortune is a program which prints a random quote everytime you run it. I put it there, so everytime I run a bash, I'm pleased with a random quote!
I even installed the fortune chuck norris mod from Arch's aur, so sometimes I get a random chuck norris fact there.

And finally, my PS1 is the Arch's standard, except I prefer to see the whole path of where I am instead of just the folder name (/w instead of /W), so it saves me some pwd.



So, got any tips to share?

 

It looks like you and I are alone, Enunes. I'm using fortune-mod in my .bashrc as well, after seeing this post, but I use it with the "archlinux" plugin. I also have a pair of new (and very useful aliases):

Code:

alias df='df -hT' ##filesystem usage
alias dudir='du -hs' ##get the size of a directory

 

Code:

alias dammit=iceweasel "http://www.distrowatch.com"

 

I've got a fairly fancy PS1 I picked up somewhere but I can't recall exactly...otherwise it's the stock (k)ubuntu one.

anyway it's this:

Code:

PS1="\n\[\033[35m\]\$(/bin/date)\n\[\033[32m\]\w\n\[\033[1;31m\]\u@\h: \[\033[1;34m\]\$(/usr/bin/tty | /bin/sed -e 's:/dev/::'): \[\033[1;36m\]\$(/bin/ls -1 | /usr/bin/wc -l | /bin/sed 's: ::g') files \[\033[1;33m\]\$(/bin/ls -lah | /bin/grep -m 1 total | /bin/sed 's/total //')b\[\033[0m\] -> \[\033[0m\]"

Depending on how many files there are in a directory it might take a while to CD into it.

 

Oh... wow... my horizons have been broadened.

 

Yeah.. now that's pretty different.

Just in case, anyone which wants to 'try' it without breaking anything, you can paste that PS1 code in your terminal and check how that PS1 looks like. In case ctrlC/ctrlV doesnt work, you can try right click+copy/paste. Just executing "PS1=" something will change your PS1 and it will be reseted once you restart your terminal (you can try PS1=adjfaodjf to check what i mean).

I shall look after a new one for me now, my standard stock one seems sooo funless now.
