Shell Programming and Scripting

Hi,

can somebody please answer my questions:

1) is the "sh" available on all unix systems at /bin/sh ???

2) how to make the following call working:

`which java` -cp $JAVA_HOME MyClass

since I do not know the location of java :-((

1) Do ls -1 /bin/*sh
- This would probably list of shells available of your machine.

/bin/bash*
/bin/csh*
/bin/jsh*
/bin/ksh*
/bin/pfcsh*
/bin/pfksh*
/bin/pfsh*
/bin/remsh@
/bin/rksh*
/bin/rsh*
/bin/sh*
/bin/ssh*
/bin/tcsh*
/bin/zsh*


2)Find out the java path on you machine,most of the times its under /usr/bin/java,else do a find for java

Add that path (/usr/bin/java) to your PATH variable
Once the PATH is set ,you dont have to say which java.

Please search the forum of adding PATH to your shell .profile file


Thanks

I think u did not understand my questions:

1) is the location /bin/sh a standard on all Unix systems (aix, hp-ux, linux, sun ...)???



2) since I do not want to care where java located:
`which java` -cp $JAVA_HOME MyClass

:-(

from the Unix specification:

It is the standard location for a Bourne-type shell; it may or may not be a POSIX shell

If java is not in your PATH, then which (which is an unreliable command; there are at least two versions of it, one of which will not work in a Bourne-type shell) will probably not find it.

If java is in your PATH, you don't need which, just use the command name.
