试着写的一个shell脚本

#/bin/shell

file1="./ROOT_bak.zip";

file2="./ROOT.zip";

file3="/home/tomcat04/ROOT.zip"

if [ -f "$file1" ];

then
echo rm -rf ROOT_bak.zip;

        rm -rf ROOT_bak.zip;

else     
echo ROOT_bak.zip not exist;
exit;

fi

if [ -f "$file2" ];

then 
echo mv ROOT.zip ROOT_bak.zip;

        mv ROOT.zip ROOT_bak.zip;

else  
echo ROOT.zip not exist;
exit;

fi

if [ -f "$file3" ];

then 
echo mv /home/tomcat04/ROOT.zip ./ ;
mv /home/tomcat04/ROOT.zip ./ ;

else     
echo /home/tomcat04/ROOT.zip not exist;
exit;

fi
