备份脚本的问题，急！！！！

lvan6750

写了一个备份的脚本，有2个device同时运行。前面都还正常，可是到了往tape写文件的时候，“wait”不起作用了（脚本中红色标记的地方），直接就运行后面的命令，将tape move出来了，贴上log和脚本，老大们，帮忙看下，急。。。。

哎。。。
没人理

susbin

You might want to try this:

$TAR cvf $TAPE0 $LINE0

if [ $? = 0 ] ; then
    $TAR cvf $TAPE1 $LINE1
else
    echo "Could not ... "
fi

问题已解决
a=

   while [ "$a" != "x" ]

   do

       sleep 60

        

       a="x`ps -aef |grep tar | grep /dev/rmt |grep -v grep`"  

   done
