# 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"
