calling a prg from the shell!!!




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:


quote:
applications should note that the standard path to the shell cannot be assumed to be either /bin/sh or /usr/bin/sh, and should be determined by interrogation of the path returned by getconf path , ensuring that the returned pathname is an absolute pathname and not a shell built-in.

for example, to determine the location of the standard sh utility:

command -v sh

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.
