##### bash framework
# some useful bash functions to make things easier

## use printf for safety purposes
# http://www.etalabs.net/sh_tricks.html
# @param string what to say
say ()    { printf %s\\n "$*" ; }
sayn ()   { printf %s "$*" ; }

## check if user is root
root ()   { [[ "$EUID" -eq 0 ]] ; }

## check if last call had errors
## if yes print generic error message and exit
ok() { [[ "$?" -ne 0 ]] && echo "ERROR, aborting." && exit 1; }

## colors
# use ANSI escape codes
