~/.profile content

~/.profile: executed by the command interpreter for login shells.

This file is not read by bash(1), 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 setting the umask

for ssh logins, install and configure the libpam-umask package.

#umask 022

if running bash

if [ -n "$BASH_VERSION" ]; then # include .bashrc if it exists if [ -f "$HOME/.bashrc" ]; then . "$HOME/.bashrc" fi fi

set PATH so it includes user's private bin if it exists

if [ -d "$HOME/bin" ] ; then PATH="$HOME/bin:$PATH" fi

set PATH so it includes user's private bin if it exists

if [ -d "$HOME/.local/bin" ] ; then PATH="$HOME/.local/bin:$PATH" fi

~/.bashrc: executed by bash(1) for non-login shells.

for examples

If not running interactively, don't do anything

case $- in i) ;; *) return;; esac

don't put duplicate lines or lines starting with space in the history.

See bash(1) for more options

HISTCONTROL=ignoreboth

append to the history file, don't overwrite it

shopt -s histappend

for setting history length see HISTSIZE and HISTFILESIZE in bash(1)

HISTSIZE=1000 HISTFILESIZE=2000

check the window size after each command and, if necessary,

update the values of LINES and COLUMNS.

shopt -s checkwinsize

If set, the pattern "**" used in a pathname expansion context will

match all files and zero or more directories and subdirectories.

#shopt -s globstar

make less more friendly for non-text input files, see lesspipe(1)

[ -x /usr/bin/lesspipe ] && eval "$(SHELL=/bin/sh lesspipe)"

set variable identifying the chroot you work in (used in the prompt below)

if [ -z "${debian_chroot:-}" ] && [ -r /etc/debian_chroot ]; then debian_chroot=$(cat /etc/debian_chroot) fi

set a fancy prompt (non-color, unless we know we "want" color)

case "$TERM" in xterm-color|*-256color) 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

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

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

colored GCC warnings and errors

#export GCC_COLORS='error=01;31:warning=01;35:note=01;36:caret=01;32:locus=01:quote=01'

some more ls aliases

alias ll='ls -alF' alias la='ls -A' alias l='ls -CF'

Add an "alert" alias for long running commands. Use like so:

sleep 10; alert

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$//''')"'

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

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).

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 fi
