Server usage clause fails to display under Unix

[John Sinues]

I've bundled my server code into an executable JAR file. Under Windows (XP/2000), it behaves properly as shown below:

C:\dev>java -version
java version "1.4.1_02"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1_02-b06)
Java HotSpot(TM) Client VM (build 1.4.1_02-b06, mixed mode)
C:\dev>java -jar Server.jar -?
suncertify.server.ConnectionFactoryImpl [-hHostname] [-pPortNumber] [-fDBFile]
        -hHostname:   hostname, default=localhost
        -pPortNumber: service port, default=1099
        -fDBFile:     database file, default=db.db

Unfortunately, when I run the same code under:
RH Linux (Kernal v2.4.20), Java v1.4.1_02-b06
or
SunOS (v5.8), Java v1.4.1_01-b01
I receive the following output:

$ java -jar Server.jar -?
java: No match.

When I type "java -?" under RH or SunOS, I receive the same output, java: No match.. However, according to the java usage clause, "-?" and "-help" are suppose to produce the same results, but they do not.
Any ideas?
John

Hi John
Simple problem: on both systems you are using csh:

[andrewm@andrewm andrewm]$ bash
[andrewm@andrewm andrewm]$ java -?
Usage: java [-options] class [args...]
           (to execute a class)
   or  java -jar [-options] jarfile [args...]
           (to execute a jar file)
...

[andrewm@andrewm andrewm]$ sh
sh-2.05b$ java -?
Usage: java [-options] class [args...]
           (to execute a class)
   or  java -jar [-options] jarfile [args...]
           (to execute a jar file)
...

sh-2.05b$ csh
[andrewm@andrewm ~]$ java -?
java: No match.

Obviously the c shell is interpereting the -? option. If you quote the option, the shell will not attempt to interperet it:

[andrewm@andrewm andrewm]$ csh
[andrewm@andrewm ~]$ java '-?'
Usage: java [-options] class [args...]
           (to execute a class)
   or  java -jar [-options] jarfile [args...]
           (to execute a jar file)

Just for completeness:

[andrewm@andrewm andrewm]$ ksh
$ java -?  
Usage: java [-options] class [args...]
           (to execute a class)
   or  java -jar [-options] jarfile [args...]
           (to execute a jar file)
...

$ [andrewm@andrewm andrewm]$ ash
$ java -?
Usage: java [-options] class [args...]
           (to execute a class)
   or  java -jar [-options] jarfile [args...]
           (to execute a jar file)

[andrewm@andrewm andrewm]$ bsh
$ java -?
Usage: java [-options] class [args...]
           (to execute a class)
   or  java -jar [-options] jarfile [args...]
           (to execute a jar file)

This is all the shells I have installed So I will stick with my theory that you are using the C shell.

Thanks Andrew. You are correct in that I was using a variation of csh (tcsh in my case). After changing to sh or quoting the option, e.g. '-?', everything worked fine.
Thanks again,
