We have few scripts where we are using grep -w option to do exact matching of the pattern. This works fine on most of our servers.
But I have encounter a very old HP-UX System(HP-UX B.11.00) where grep -w option is not available.

CMIGREP(1) General Commands Manual CMIGREP(1)
NAME
cmigrep - search in ocaml compiled interface files
SYNOPSIS
cmigrep <options> <module-expression>
DESCRIPTION
This manual page documents briefly the cmigrep command. This manual page was written for the Debian GNU/Linux distribution because the
original program does not have a manual page.
cmigrep allows to search for information in compiled interfaces of OCaml modules. By default, the search applies to the modules described
in the .cmi files in the curent directory and in the ocaml standard directory, but this can be changed with the -I option (see below).
The argument <module-expr> can be an exact module name, or a shell wildcard. Multiple modules can be specified. Example: "ModA ModB
Foo*.Make" means to search ModA, ModB, and any submodule Make of a module that starts with Foo.
OPTIONS
General Options
-I directory
Add directory to the search path for modules
-package packages
comma separated list of findlib packages to search
open modules
comma separated list of open modules (in order!)
-help, --help
display list of options
Search Patterns
-t regexp
print types with matching names
-r regexp
print record field labels with matching names
-c regexp
print constructors with matching names
-p regexp
print polymorphic variants with matching names
-m regexp
print all matching module names in the path
-e regexp
print exceptions with matching constructors
-v regexp
print values with matching names
-o regexp
print all classes with matching names
-a regexp
print all names which match the given expression

Examples can be found on /usr/share/doc/cmigrep/README.
