Unix Expressions

Hi to all,
this is my first time in the forum...and I know some basic's about UNIX...
I want to write an expression to validate a field.
field is varchar2, length is 5, can be from '00001' to '99999'.
no loops or if condition, just check the value if between these two numbers it is OK if it is '00000' expression will fail.
How can I do this, and could you explain some details about how it is done.

Thanks

Habeeb

Sounds very oracle to me...
I though I knew a little unix, reading this post makes me doubt...
What do you call expression?
Is it a simple test condition you are looking for?

yes, its a simple test
will this work
egrep '[1-9]'

or if I can provide a ragne like this
egrep '['00001'-'99999']
will this work?
