linux /unix下循环加载文件shell

在linux上或unix环境下在没有ide的情况下编译/运行java程序都会遇到加载lib库的问题,以下shell可以改告成加载所有jar lib库到CLASSPATH中:
ls *.jar >list.txt
TMPCLASSPATH='';
for i in `cat list.txt`; do
     TMPCLASSPATH=$i:$TMPCLASSPATH
done
echo $TMPCLASSPATH
CLLASSPATH=$TMPCLASSPATH:$CLLASSPATH
export CLLASSPATH

或

TMPCLASSPATH='';
for i in `ls *.jar`; do
     TMPCLASSPATH=$i:$TMPCLASSPATH
done
echo $TMPCLASSPATH
CLLASSPATH=$TMPCLASSPATH:$CLLASSPATH
export CLLASSPATH
