It's simple. It lacks teh bling. But I'm tired of typing sudo pacman.

2 minor comments:
1. for "psgrep" there's "pgrep" command. There's also "pkill" BTW smile.
2. for "extract" there's nice tool named "atool" (available in AUR)

I use it quite often, if I'm compiling something or during the boot process something catches my eye I hit ^S to stop, scroll up hoping that the message hasn't been pushed out the buffer, find the message and read it. ^Q to continue.

The thing I miss the most when it I sit down to someone elses machine is

PS1='$ '

.

The rest of my .bashrc is pretty basic:

if [ "$(hostname)" = "coppermine" ]; then
    alias ls='ls -G'
    EDITOR='/usr/local/bin/vim'
else
    alias ls='ls --color'
    EDITOR='/usr/bin/vim'

alias ll='ls -lh'
alias u='whoami'
alias h='hostname'

MAIL="$HOME/Maildir/"
PS1='$ '

CLASSPATH='.'
for jar in ~/lib/*.jar; do
    CLASSPATH="$CLASSPATH:$jar"
done

export PS1 MAIL EDITOR CLASSPATH

That's a point, but as for the boot messages, you can always scroll backwards or check the logs/dmesg, and as for the terminals, you can simply increase the buffer size... set it to 2000-3000 lines, that should be enough for everything. Or just redirect the output into a file (using "make | tee make.log" for example).

In any case, I find accidently hitting ^S more annoying, because it can happen quite often if you use keyboard shortcuts a lot. And if you didn't notice that you accidently hit it in some terminal, it's even worse.

Re: basic ~/.bashrc ~/.bash_profile tips thread

hmmmmmm that's a new option for the eject command, it didn't used to be there wink  In fact, on my suse 10.1 system, it's not an option.  However, on the arch system it is. Interesting.

dvdo = dvd open
dvdc = dvd close

was easy for me to remember that way wink  I can be a bit forgetful ..... so i HAD to make it easy lol.

Re: basic ~/.bashrc ~/.bash_profile tips thread

I'm a laptop user and I like to use the following :

function bat1()
{
    echo $(( $(awk ' /remaining/ {print $3} ' /proc/acpi/battery/BAT0/state) * 100 / 71590 ))
}


function bat2()
{
    echo $(( $(awk ' /remaining/ {print $3} ' /proc/acpi/battery/BAT1/state) * 100 / 46620 ))
}


PS1="$(bat1)/$(bat2) u@h W $ "

# ALIAS

alias ls='ls --color=always --classify'
alias ll='ls --color=always --classify -alh | less'
alias pingg='ping -c 4 www.google.fr'
alias pingr='ping -c 4 192.168.1.1'
alias lss="ls -Ssh --color=always --classify"
alias la='ls -a --color=always --classify'

Prompt looks like that :

75/50 john@darkstar.net / $

It show the batteries %life remaining.

The functions may look somewhat weird but nesting things like that is faster than any other method I tried (using times command).

And giving the total capacity as a direct value avoids looking for it in /proc.

If you find a function that is faster than mine, I would be glad to test it.

I kind of like mmv

NAME
       mmv - move/copy/append/link multiple files by wildcard patterns

SYNOPSIS
       mmv [-m|x|r|c|o|a|l|s] [-h] [-d|p] [-g|t] [-v|n] [from to]

DESCRIPTION
       Mmv moves (or copies, appends, or links, as specified) each source file matching a from pattern to the target name specified by
       the to pattern.  This multiple action is performed safely, i.e. without any unexpected deletion of files due to  collisions  of
       target  names  with  existing filenames or with other target names.  Furthermore, before doing anything, mmv attempts to detect
       any errors that would result from the entire set of actions specified and gives the user the choice  of  either  proceeding  by
       avoiding the offending parts or aborting.

Re: basic ~/.bashrc ~/.bash_profile tips thread

What a nice thread smile

So I have any Questions:

Why exists .bashrc and .bash_profile, when I only need one?

I will symlink .bashrc to .bash_profile, can I do this or must I attend anything?


These extract funbction is very cool 8), but how can I use the function?

I have try extract foo.tar, but extract is not found

# Functions
extract () {
   if [ -f $1 ] ; then
      case $1 in
         *.tar.bz2)   tar xjf $1      ;;
         *.tar.gz)   tar xzf $1      ;;
         *.bz2)      bunzip2 $1      ;;
         *.rar)      rar x $1      ;;
         *.gz)      gunzip $1      ;;
         *.tar)      tar xf $1      ;;
         *.tbz2)      tar xjf $1      ;;
         *.tgz)      tar xzf $1      ;;
         *.zip)      unzip $1      ;;
         *.Z)      uncompress $1   ;;
         *)         echo "'$1' cannot be extracted via extract()" ;;
      esac
   else
      echo "'$1' is not a valid file"

Make sure that you either source your <code>.bashrc</code> or log out and log back on before trying to use the functions.  Just adding them to your file won't work until it gets read once again:

$ source ~/.bashrc

            *.tar)      tar xf $1       ;;  
            *.tbz2)     tar xjf $1      ;;  
            *.tgz)      tar xzf $1      ;;  
            *.zip)      unzip $1        ;;  
            *.Z)        uncompress $1   ;;  
            *)          echo "'$1' cannot be extracted" ;;
        esac
    else
        echo "'$1' is not a file"
    fi  
}

ex:  create tar.bz2 SOME_FILES  would create  SOME_FILES.tar.bz2 

Ideally, It could even be extended to
create zip -n NAME -f FILE1 FILE2 ...  which would create NAME.zip containing FILE1 FILE2 ....

Re: basic ~/.bashrc ~/.bash_profile tips thread

I got fedup typing "sudo pacman -Syu" and "sudo pacman -S foo" so wrote a fuction do it for me

pacman(){
    case $1 in
        -ss)  shift && pacsarch $*                  ;;
        -a)   shift && sudo /usr/bin/pacman -A $*   ;;
        -u)   shift && sudo /usr/bin/pacman -U $*   ;;
        -s)   shift && sudo /usr/bin/pacman -S $*   ;;
        -sy)  shift && sudo /usr/bin/pacman -Sy $*  ;;
        -su)  shift && sudo /usr/bin/pacman -Su $*  ;;
        -syu) shift && sudo /usr/bin/pacman -Syu $* ;;
        -R)   shift && sudo /usr/bin/pacman -Rs $*  ;;
        -r)   shift && sudo /usr/bin/pacman -R $*   ;;
        -*)   /usr/bin/pacman $*                    ;;
    esac
}

Is there a way to write a function that does the opposite of this

smush () {
    FILE=$1
    case $FILE in
        *.tar.bz2) shift && tar cjf $FILE $* ;;
        *.tar.gz) shift && tar czf $FILE $* ;;
        *.tgz) shift && tar czf $FILE $* ;;
        *.zip) shift && zip $FILE $* ;;
        *.rar) shift && rar $FILE $* ;;
    esac
}

usage: smush ~/foo.tar.bz2 ./foo ./bar
I've don't use zip or rar so have no idea if they will work, but you get the idea.

Re: basic ~/.bashrc ~/.bash_profile tips thread

Thanks TomE.

yur function works well

i was sick of doing all that typing so i made some alias to quicken things up

in my home directory i added
#For Updating
alias u='sudo pacman -Syu'
#Grap new file list, but dont download
alias nu='yes no | sudo pacman -Syu'
#install
alias i='sudo pacman -S'

and im my /etc i added
#Search for file from repositories
alias s='pacman -Ss'
#Search Installed packages
alias si='pacman -Qi | grep'
#Search Package Groups
alias sg='pacman -Sg'
#Search for Name of Depository
alias sn='pacman -Sl'
#Pull up info on an installed package
alias sd='pacman -Qi'

things are really easy now, 
if i need to install something, just
i $PROG
updates
u
Search the dependency of a program
sd $PROG
etc...
