nano question

Folks,

I am Remote Desktop-ing to a machine and launch nano in a terminal to create some start ans stop files.  Here is one:

bml0066:tomcat administrator$ cat start1.sh
#!/bin/sh  Startup script for the tomcat1 instance
#
CATALINA_HOME=/usr/local/tomcat
CATALINA_BASE=/usr/local/tomcat1
export CATALINA_HOME CATALINA_BASE

$CATALINA_HOME/bin/catalina.sh start


When I try to execute it just by

bml0066:tomcat administrator$ sudo ./start1.sh
/bin/sh: Startup: No such file or directory

But if I execute it in a sub-shell, then it does not complain:

bml0066:tomcat administrator$ sudo sh ./start1.sh
Using CATALINA_BASE:   /usr/local/tomcat1
Using CATALINA_HOME:   /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat1/temp
Using JRE_HOME:        /System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK/Home
Using CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar

So, the question is what to do to be able to do just

sudo ./start1.sh

?

The permission mask for start1.sh is:
-rwxr-xr-x  1 root  staff  192 Mar 17 15:16 start1.sh

The same thing for the tomcat startup.sh is:
-rwxr-xr-x@ 1 root  wheel  1956 Mar  5 08:09 bin/startup.sh

The difference is the quarantine bit at the and of the mask.

Thanks ahead,

János
