Executed by bash for non-login shells. See ~/usr/share/doc/bash/examples/startup-files~ (in the package =bash-doc=) for examples. |
|||
|
|||
If not running interactively, don't do anything. |

#+end_src |

|

Don't put duplicate lines or lines starting with space in the history. |
|||
|
|||
#+begin_src shell |
|||
HISTCONTROL=ignoreboth |
|||
#+end_src |
|||
|
|||
Append to the history file, don't overwrite it. |
|||
|
|||
#+begin_src shell |
|||
shopt -s histappend |
|||
#+end_src |
|||
|
|||
For setting history length see ~HISTSIZE~ and ~HISTFILESIZE~. |
|||
|
|||
#+begin_src shell |
|||
HISTSIZE=1000 |
|||
HISTFILESIZE=2000 |
|||
#+end_src |
|||
|
|||
Check the window size after each command and, if necessary, update the values of ~LINES~ and ~COLUMNS~. |
|||
|
|||
#+begin_src shell |
|||
shopt -s checkwinsize |
|||
#+end_src |
|||
|
|||
If set, the pattern ="**"= used in a pathname expansion context will match all files and zero or more directories and subdirectories. |
|||
|
|||
#+begin_src shell |

#shopt -s globstar |
|||
#+end_src |

|

Make less more friendly for non-text input files. |
|||
|
|||
#+begin_src shell |
|||
[ -x /usr/bin/lesspipe ] && eval "$(SHELL=/bin/sh lesspipe)" |
|||
#+end_src |
|||
|
|||
Set variable identifying the chroot you work in (used in the prompt below). |
|||
|
|||
#+begin_src shell |
|||
if [ -z "${debian_chroot:-}" ] && [ -r /etc/debian_chroot ]; then |
|||
debian_chroot=$(cat /etc/debian_chroot) |
|||
fi |
|||
#+end_src |
|||
|
|||
Set a fancy prompt (non-color, unless we know we "want" color). |
|||
|
|||
#+begin_src shell |
|||
case "$TERM" in |
|||
xterm-color|*-256color) color_prompt=yes;; |
|||
esac |
|||
#+end_src |
|||
|
|||
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. |
|||
|
|||
#+begin_src shell |
|||
#force_color_prompt=yes |
|||
#+end_src |
|||
|
|||
If we have color support; assume it's compliant with =Ecma-48 (ISO/IEC-6429)=. |
|||
|
|||
#+begin_src shell |
|||
if [ -n "$force_color_prompt" ]; then |
|||
if [ -x /usr/bin/tput ] && tput setaf 1 >&/dev/null; then |
|||
color_prompt=yes |
|||
else |
|||
color_prompt= |
|||
fi |
|||
fi |
|||
#+end_src |
|||
|
|||
Lack of such support is extremely rare, and such a case would tend to support ~setf~ rather than ~setaf~. |
|||
|
|||
#+begin_src shell |
|||
if [ "$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 |
|||
#+end_src |
|||
|
|||
If this is an xterm set the title to ~user@host:dir~. |
|||
|
|||
#+begin_src shell |
|||
case "$TERM" in |
|||
xterm*|rxvt*) |
|||
PS1="\[\e]0;${debian_chroot:+($debian_chroot)}\u@\h: \w\a\]$PS1" |
|||
;; |
|||
*) |
|||
;; |
|||
esac |
|||
#+end_src |
|||
|
|||
Enable color support of ~ls~ and also add handy aliases. |
|||
|
|||
#+begin_src shell |
|||
if [ -x /usr/bin/dircolors ]; then |
|||
test -r ~/.dircolors && eval "$(dircolors -b ~/.dircolors)" || eval "$(dircolors -b)" |
|||
alias ls='ls --color=auto' |
|||
#alias dir='dir --color=auto' |
|||
#alias vdir='vdir --color=auto' |
|||
|
|||
alias grep='grep --color=auto' |
|||
alias fgrep='fgrep --color=auto' |
|||
alias egrep='egrep --color=auto' |
|||
fi |
|||
#+end_src |
|||
|
|||
Colored =GCC= warnings and errors. |
|||
|
|||
#+begin_src shell |
|||
#export GCC_COLORS='error=01;31:warning=01;35:note=01;36:caret=01;32:locus=01:quote=01' |
|||
#+end_src |
|||
|
|||
Some more ~ls~ aliases. |
|||
|
|||
#+begin_src shell |
|||
alias ll='ls -alF' |
|||
alias la='ls -A' |
|||
alias l='ls -CF' |
|||
#+end_src |
|||
|
|||
Add an ~alert~ alias for long running commands. |
|||
|
|||
#+begin_src shell |
|||
alias alert='notify-send --urgency=low -i "$([ $? = 0 ] && echo terminal || echo error)" "$(history|tail -n1|sed -e '\''s/^\s*[0-9]\+\s*//;s/[;&|]\s*alert$//'\'')"' |
|||
#+end_src |
|||
|
|||
Use like so: |
|||
|
|||
#+begin_example |
|||
sleep 10; alert |
|||
#+end_example |
|||
|
|||
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. |
|||
|
|||
#+begin_src shell |
|||
if [ -f ~/.bash_aliases ]; then |
|||
. ~/.bash_aliases |
|||
fi |
|||
#+end_src |
|||
|
|||
Enable programmable completion features. You don't need to enable this, if it's already enabled in ~/etc/bash.bashrc~ and ~/etc/profile~ sources ~/etc/bash.bashrc~. |
|||
|
|||
#+begin_src shell |
|||
if ! shopt -oq posix; then |
|||
if [ -f /usr/share/bash-completion/bash_completion ]; then |
|||
. /usr/share/bash-completion/bash_completion |
|||
elif [ -f /etc/bash_completion ]; then |
|||
. /etc/bash_completion |
|||
fi |

Executed by the command interpreter for login shells. |
|||
|
|||
This file is *not* read by bash, if ~~/.bash_profile~ or ~~/.bash_login~ exists. See =/usr/share/doc/bash/examples/startup-files= for examples. The files are located in the bash-doc package. |
|||
|
|||
The default umask is set in ~/etc/profile~. For =SSH= logins, install and configure the =libpam-umask= package. |
|||
|
|||
#+begin_src shell |
|||
#umask 022 |
|||
#+end_src |
|||
|
|||
If we're running =bash= make sure to include ~~/.bashrc~ if it exists. |
|||
|
|||
#+begin_src shell |
|||
if [ -n "$BASH_VERSION" ]; then |
|||
if [ -f "$HOME/.bashrc" ]; then |
|||
. "$HOME/.bashrc" |
|||
fi |
|||
fi |
|||
#+end_src |
|||
|
|||
Add private bin directories to the ~$PATH~ (if they exist). |
|||
+ ~$HOME/bin~ |
|||
+ ~$HOME/.local/bin~ |
|||
|
|||
#+begin_src shell |
|||
if [ -d "$HOME/bin" ]; then |
|||
PATH="$HOME/bin:$PATH" |
|||
fi |
|||
if [ -d "$HOME/.local/bin" ]; then |
|||
PATH="$HOME/.local/bin:$PATH" |
|||
fi |
|||
#+end_src |
|||
|
|||
Add ~$HOME/go/bin~ to the ~$PATH~ if it exists. |
|||
|
|||
#+begin_src shell |
|||
if [ -d "$HOME/go/bin" ]; then |
|||
PATH="$HOME/go/bin:$PATH" |
|||
fi |
|||
#+end_src |
|||
|
|||
Auto run =startx= on login if there's no display server running. |
|||
|
|||
#+begin_src shell |
|||
if [ -z "${DISPLAY}" ] && [ "${XDG_VTNR}" -eq 1 ]; then |
|||
exec startx |
|||
fi |

#+end_src |
