Personalitzacions bashrc

Cal mirar el fitxer comu /etc/bash/bashrc (Gentoo) o bé /etc/bash.bashrc (Suse) contingui:

Per personalitzar un usuari en concret, editar ~/.bashrc

Prompt amb color

if [[ ${EUID} == 0 ]] ; then
  PS1='\[\033[01;31m\]\h\[\033[01;34m\] \W \$\[\033[00m\] '
else
  PS1='\[\033[01;32m\]\u@\h\[\033[01;34m\] \w \$\[\033[00m\] '
fi

Si és \w es tot el cami si és \W només directori actual:

\! History number of current command
\# Command number of current command
\d Current date
\h Host name
\n Newline
\s Shell name
\t Current time
\u User name
\W Current working directory
\w Current working directory (full path)

Prompt color Original de Ubuntu

# set a fancy prompt (non-color, unless we know we "want" color)
case "$TERM" in
    xterm-color) color_prompt=yes;;
esac

# uncomment for a colored prompt, if the terminal has the capability; turned
# off by default to not distract the user: the focus in a terminal window
# should be on the output of commands, not on the prompt
#force_color_prompt=yes

if [ -n "$force_color_prompt" ]; then
    if [ -x /usr/bin/tput ] && tput setaf 1 >&/dev/null; then
        # We have color support; assume it's compliant with Ecma-48
        # (ISO/IEC-6429). (Lack of such support is extremely rare, and such
        # a case would tend to support setf rather than setaf.)
        color_prompt=yes
    else
        color_prompt=
    fi
fi

if [ "$color_prompt" = yes ]; then
    PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '
else
    PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w\$ '
fi
unset color_prompt force_color_prompt

Posar titol a les finestres

Apareix al connectar amb SSH, o obrir xterm.

# If this is an xterm set the title to user@host:dir
case "$TERM" in
xterm*|rxvt*)
   PS1="\[\e]0;${debian_chroot:+($debian_chroot)}\u@\h: \w\a\]$PS1"
   ;;
*)
   ;;
esac

Fer que tinguin color les comandes

# enable color support of ls and also add handy aliases
if [ -x /usr/bin/dircolors ]; then
   test -r ~/.dircolors && eval "$(dircolors -b ~/.dircolors)" || eval "$(dircolors -b)"
   alias ls='ls --color=auto'
   alias dir='dir --color=auto'
   alias vdir='vdir --color=auto'
   alias grep='grep --color=auto'
   alias fgrep='fgrep --color=auto'
   alias egrep='egrep --color=auto'
fi

Alies útils

Per fer Alies de comandes afegir al final de ~/.bashrc:

alias l='ls -alF'
alias ..='cd ..'
alias ...='cd ../..'

Alies utils Originals Ubuntu

# some more ls aliases
#alias ll='ls -l'
#alias la='ls -A'
#alias l='ls -CF'

# Alias definitions.
# You may want to put all your additions into a separate file like
# ~/.bash_aliases, instead of adding them here directly.
# See /usr/share/doc/bash-doc/examples in the bash-doc package.

if [ -f ~/.bash_aliases ]; then
    . ~/.bash_aliases
fi

Resum Tot usat per mi

A afegir al final de ~/.bashrc o millor al /etc/bashrc /etc/bash.bashrc per tal que sigui per tots els usuaris
