# The latest version as installed by the Cygwin Setup program can

# Modifying /etc/skel/.bashrc directly will prevent
# setup from updating it.

# The copy in your home directory (~/.bashrc) is yours, please

# Shell Options
#
# See man bash for more options...
#
# Don't wait for job termination notification
# set -o notify
#
# Don't use ^D to exit
# set -o ignoreeof
#
# Use case-insensitive filename globbing
shopt -s nocaseglob
#
# Make bash append rather than overwrite the history on disk
# shopt -s histappend
#
# When changing directory small typos can be ignored by bash
# for example, cd /vr/lgo/apaache would find /var/log/apache
# shopt -s cdspell

# Completion options
#
# These completion tuning parameters change the default behavior of bash_completion:
#
# Define to access remotely checked-out files over passwordless ssh for CVS
# COMP_CVS_REMOTE=1
#
# Define to avoid stripping description in --option=description of './configure --help'
# COMP_CONFIGURE_HINTS=1
#
# Define to avoid flattening internal contents of tar files
# COMP_TAR_INTERNAL_PATHS=1
#
# Uncomment to turn on programmable completion enhancements.
# Any completions you add in ~/.bash_completion are sourced last.
# [[ -f /etc/bash_completion ]] && . /etc/bash_completion

# History Options
#
# Don't put duplicate lines in the history.
# export HISTCONTROL=$HISTCONTROL${HISTCONTROL+,}ignoredups
#
# Ignore some controlling instructions
# HISTIGNORE is a colon-delimited list of patterns which should be excluded.
# The '&' is a special pattern which suppresses duplicate entries.
# export HISTIGNORE=$'[ \t]*:&:[fb]g:exit'
# export HISTIGNORE=$'[ \t]*:&:[fb]g:exit:ls' # Ignore the ls command as well
#
# Whenever displaying the prompt, write the previous line to disk
# export PROMPT_COMMAND="history -a"

# Aliases
#
# Some people use a different file for aliases
# if [ -f "${HOME}/.bash_aliases" ]; then
#   source "${HOME}/.bash_aliases"
# fi
#
# Some example alias instructions
# If these are enabled they will be used instead of any instructions
# they may mask.  For example, alias rm='rm -i' will mask the rm
# application.  To override the alias instruction use a \ before, ie
# \rm will call the real rm not the alias.
#
# Interactive operation...
# alias rm='rm -i'
# alias cp='cp -i'
# alias mv='mv -i'
#
# Default to human readable figures
alias df='df -h'
alias du='du -h'
#
# Misc :)
alias less='less -R'                          # raw control characters
# alias whence='type -a'                        # where, of a sort
alias grep='grep --color'                     # show differences in colour
alias egrep='egrep --color=auto'              # show differences in colour
alias fgrep='fgrep --color=auto'              # show differences in colour
#
# Some shortcuts for different directory listings
alias ls='ls -h --color=tty'                 # classify files in colour
alias dir='ls --color=auto --format=vertical'
# alias vdir='ls --color=auto --format=long'
# alias ll='ls -l'                              # long list
# alias la='ls -A'                              # all but . and ..
# alias l='ls -CF'                              #

# Umask
#
# /etc/profile sets 022, removing write perms to group + others.
# Set a more restrictive umask: i.e. no exec perms for others:
# umask 027
# Paranoid: neither group nor others have any perms:
# umask 077

# Functions
#
# Some people use a different file for functions
# if [ -f "${HOME}/.bash_functions" ]; then
#   source "${HOME}/.bash_functions"

#
# Some example functions:
#
# a) function settitle
# settitle () 
# { 
#   echo -ne "\e]2;$@\a\e]1;$@\a";

# 
# b) function cd_func
# This function defines a 'cd' replacement function capable of keeping, 
# displaying and accessing history of visited directories, up to 10 entries.
# To use it, uncomment it, source this file and try 'cd --'.
