unalias mv cp 2> /dev/null
# Ask for confirmation before overwriting files. Especially useful when moving
# to a different directory. No alias for `rm` because I specify the files to
# remove directly, so I know what will happen.
alias mv='mv -i'
# Additionally preserve all file attributes when copying, this includes
# copying symbolic links as is without dereferencing them.
alias cp='cp -i -a'


# Make sure there is no alias named ls as it causes problems with the
# following ls function on (at least) bash 4.0.35.
unalias ls 2> /dev/null
# Improved ls which displays the files in columns (-C), visualizes
# directories, links and other special files (-F) and pages everything through
# less.
#
# If available use GNU ls with colorized output. If it isn't available try
# normal ls which needs CLICOLOR_FORCE so it displays colors when used with a
# pager. If none work no colors are used.
#
# See `setup.sh` for details. LS_ENV, LS_PATH, LS_COLOR are replaced with the
# correct values when this file is generated.

    LS_ENV LS_PATH LS_COLOR -C -F "$@" 2>&1 | less
