shell脚本中自定义日志记录到文件

# adirname - return absolute dirname of given file
adirname() { odir=`pwd`; cd `dirname $1`; pwd; cd "${odir}"; }
MYNAM=`basename "$0"`
MYDIR=`adirname "$0"`
MYHOME="/home/shell/script"
MYLOG_PATH="${MYHOME}/logs"
MYLOG="${MYLOG_PATH}/${MYNAM}_`date +%F`.log"
# function logging
function loginfo(){
	echo "$1"
	echo "$(date -d today +"%Y%m%d %H:%M:%S") - $1"  >> ${MYLOG} 2>> ${MYLOG}
}

loginfo "backup file war  successfully!"
