Ahhhrrrggg I’m having a brain fart…

I want to take the output of a command and redirect it to a file…
This works….
$ man cp | cat >> copy_help

but this doesn’t

keytool -help |cat >> keytool_help
It just produces… these lines…
more keytool_help
[-providerClass <provider_class_name> [-providerArg <arg>]] ...
[-providerClass <provider_class_name> [-providerArg <arg>]] ...

Why not just "man cp >> copy_help"?

That will work too... It's the keytool >> that is the problem. I can't get the help text to show up in a file.

Actually it's the 'cat' that's a problem. What happens if you type "keytool -help >> keytool_help"?

Carl

It does create a file but no help text...
more keytool_help
[-providerClass <provider_class_name> [-providerArg <arg>]] ...

That does appear to be some sort of help (command line options). Are you passing the right question to keytool? Maybe it needs "keytool --help" for example. Most of the linux tools are dash single character and double-dash word.

Don't know what system you're on and what keytool is although a quick google search finds:

http://java.sun.com/j2se/1.3/docs/to...2/keytool.html
http://developer.apple.com/documenta...keytool.1.html

Both refer to the same tool (and it uses -help, a single dash). It might be better to just reference one of these pages for more help if this is the tool you're looking for

What output do you get if you just type keytool -help without redirecting?
