.bashrc

[toad]

Just had a look at the .bashrc of 8.10 and what can I say? There's more stuff in there than you can shake a stick at! Not sure how useful it all is...

Anyway, I wondered what your ideal .bashrc looks like.

Here a couple of additions I find useful:

# my additions
alias ..='cd ..'
alias lla='ls -la'
alias update='sudo aptitude update'
alias upgrade='sudo aptitude safe-upgrade'
alias install='sudo aptitude install'
alias search='aptitude search'
alias remove='sudo aptitude remove'
alias purge='sudo aptitude remove --purge'
alias show='aptitude show -v'
alias clean='sudo aptitude clean'
alias aclean='sudo aptitude autoclean'
alias df='df -h'
alias blkid='blkid -L'

To activate your new .bashrc simply do a

source .bashrc

Please post any suggestions, improvements, whatever!

Re: .bashrc

This applies to any configuration file I modify.

I create ~/etc and store modified configuration files there. Then I symlink them to their standard locations and names. For instance, for .bashrc: cp .bashrc etc/bashrc && rm .bashrc && ln -s etc/bashrc .bashrc

Then, when I want to modify the configuration for any file I can easily find it. I keep /home in a separate partition, so when I upgrade, my files remain intact. If any configuration files I customized get overwritten by the new installation, I can easily restore them.

There is a post at https://wiki.ubuntu.com/Spec/EnhancedBash that has some good ideas.

# check the window size after each command and, if necessary,
# update the values of LINES and COLUMNS.
shopt -s checkwinsize

Re: .bashrc

I opt to keep my alias definitions in the ~/.bash_aliases file instead of cluttering up the .bashrc file.

I like that, it's simple and it's safe. You avoid the mv command - has it ever failed you or you never used it ?

I haven't got one Anyway, anything in there which you use on a regular basis?

Re: .bashrc

What I have in my ~/.bash_aliases file:

alias a='clear && alias'
alias aptClean='sudo apt-get clean; sudo apt-get autoclean; sudo apt-get autoremove'
alias chkHD='clear && sudo smartctl -a /dev/sda'
alias findit='clear && sudo find /* -mount -name'
alias fstab='clear && cat /etc/fstab'
alias gM='clear && cat /boot/grub/menu.lst'
alias ls='ls --color=auto'
alias mtab='clear && cat /etc/mtab'
alias sL='clear && cat /etc/apt/sources.list'
alias simI='sudo apt-get install --simulate '
alias simR='sudo apt-get remove --simulate '
alias simU='sudo apt-get dist-upgrade --simulate '
alias ua='clear && source ~/.bash_aliases'
alias used='clear && df -hTxtmpfs'
alias xC='clear && cat /etc/X11/xorg.conf'

Re: .bashrc

That's aptClean with a real capital C 8) I'm including some of your ideas right now, thanks!

Re: .bashrc

I had, at one time, three separate aliases for clean, autoclean, and autoremove, but as I always ran them sequentially, I decided to create the one single alias that does them all.
