無法從螞蟻命令輸出bash結果

Question

我正在編寫一個修改某些配置文件的bash腳本，以不同的用戶身份運行「ant ear war」，輸出返回值，退出到根目錄以繼續腳本的其餘部分。問題在於腳本在退出後不會繼續，並且我沒有從「ant ear war」中獲得輸出。

謝謝你的幫助。

這裏有一個例子

#When running the bash script i don't see the output. Maybe it's because I run it as root and switched to another_user. So I tried to outputing result into a variable and into a text file. Both failed 
su another_user 
cd /usr/empi/MMEMPIV741/ 
echo $(ant ear war) >> /tmp/empi_install.txt 
varant="$?" 
echo 'if zero it's success otherwise it's a failure' 

cp /usr/accessmgr/AMV741/bin/am/JBoss/AccessManager.war /usr/jboss/jboss-eap-4.3/jboss-as/server/default/deploy/ 
cp /usr/empi/MMEMPIV741/person_project/working-dir/dist/* /usr/jboss/jboss-eap-4.3/jboss-as/server/default/deploy/ 
exit 

#By this time above is exited from another_user and should return to root 
echo $varant 

echo "http://`hostname`:21080/PersonMasterIndexDQM/flex/login.jsp#"

將要在不同的用戶上下文中運行到一個單獨的腳本，並通過

su another_user -c /path/to/other.sh
