New Binary files -- different greps?

I note that your GNU/Linux output indicates that you're dealing with\r\na binary file. I suspect a difference in handling of this by your\r\ngreps.

\r\n\r\n

Check the Solaris grep's manpage and make sure there's not an option\r\nrequired to test binary files. Also try strings on the file\r\nfrom both sides to see if you can find the pattern string you're\r\nmatching on.

\r\n\r\n

Might also want to compile GNU grep on the Solaris box and see what\r\nit makes of this.

New Already did that.
As noted, at least with using 'strings'. :-)

No Solaris grep option. So I suspect it might be \\0 processing or something odd like that.

New Can it not find the expression with...
cat OCIEnv.class | grep get_env_handle

That'd help define if it is the \\0 processing then... (at least I am think it should)

Or compress it and then zcat it to grep... might bring out the flaw... ;)

New I know... but strings does some stripping...
and preprocesses the input for it.

From most any manpage:

strings - print the strings of printable characters in files.


Specifically, it (should) only (does|do) sequences of 4 characters or longer...

So, thank you very much... William Oxley! :)
