I have a bash script named ztest that looks like this:
---------------
#!/bin/bash

ls -lat

---------------

On server A it works fine, and I get a directory listing.

On server B I get nothing. As though the script did not execute!

However, I modified the script:
---------------
#!/bin/bash

ls -lat $1 >zresult

---------------

When I execute the following:
#./ztest
#cat zresult

I see the directory.
And if I execute the following:
#./ztest /etc/init.d/
#cat zresult

I see the /etc/init.d/ directory.
Bottom line: The bash script is executing.
But I am not getting/seeing any output from the script.
I have tried echo commands, >stdout, etc. but no such luck!

I am ssh'd into the server using PuTTY.
But I have no idea if this is a system configuration issue? A PuTTY issue? Some other issue?

Any ideas?

Are you sure ztest is executable on server b.

chmod +x ztest

Yes.
chmod 0755 ztest

And per my post, when the script directs output to a file, I can see the results in that file.
So I know the script is executing.
I just cannot see any of my commands being echoed.

I think that's something about FD(file descriptor). That means something about redirection in server b is changed because the default stdout device is Screen, but now it's obvious not. But unfortunately I didnot know which place to do this kinda changes. I am searching for it now.
