color_init() {
[ -n "${NOCOLOUR}" ] && return
[ -n "${MAILX_CC_TEST_NO_COLOUR}" ] && return
# We do not want color for "make test > .LOG"!
if (command -v stty && command -v tput) >/dev/null 2>&1 &&
(<&1 >/dev/null stty -a) 2>/dev/null; then
{ sgr0=`tput sgr0`; } 2>/dev/null
[ $? -eq 0 ] || return
{ saf1=`tput setaf 1`; } 2>/dev/null
[ $? -eq 0 ] || return
{ saf2=`tput setaf 2`; } 2>/dev/null
[ $? -eq 0 ] || return
{ saf3=`tput setaf 3`; } 2>/dev/null
[ $? -eq 0 ] || return
{ b=`tput bold`; } 2>/dev/null
[ $? -eq 0 ] || return
COLOR_ERR_ON=${saf1}${b} COLOR_ERR_OFF=${sgr0}
COLOR_WARN_ON=${saf3}${b} COLOR_WARN_OFF=${sgr0}
COLOR_OK_ON=${saf2} COLOR_OK_OFF=${sgr0}
unset saf1 saf2 saf3 b
fi
}
Is what i use for a make system.
