Thanks, but it is misunderstood,
the input has to be EXACT match of one of options e.g.
centos-5.5-i386 windows-2003r2-x64 freebsd-6.1-i386
so, centos/freebsd/windows are not valid input
I am looking for a shell one-liner,any command, to achieve this, grep is just an example
I could compare the length of the input string and length of the string being search/replaced, but not an elegant solution.
I need help to know how to create a script that takes string options and not only 1 charecter.

i386_get_ldt
I386_GET_LDT(2) BSD/i386 System Calls Manual I386_GET_LDT(2)NAME
i386_get_ldt, i386_set_ldt -- manage i386 per-process Local Descriptor Table entries
LIBRARY
i386 Architecture Library (libi386, -li386)
SYNOPSIS
#include <sys/types.h>
#include <machine/segments.h>
#include <machine/sysarch.h>
int
i386_get_ldt(int start_sel, union descriptor *descs, int num_sels);
int
i386_set_ldt(int start_sel, union descriptor *descs, int num_sels);
DESCRIPTION
i386_get_ldt() will return the list of i386 descriptors that the process has in its LDT. i386_set_ldt() will set a list of i386 descriptors
for the current process in its LDT. Both routines accept a starting selector number start_sel , an array of memory that will contain the
descriptors to be set or returned descs , and the number of entries to set or return num_sels.
The argument descs can be either segment_descriptor or gate_descriptor and are defined in <i386/segments.h> .
These structures are defined by the architecture as disjoint bit-fields, so care must be taken in constructing them.
RETURN VALUES
Upon successful completion, i386_get_ldt() returns the number of descriptors currently in the LDT. i386_set_ldt() returns the first selector
set. Otherwise, a value of -1 is returned and the global variable errno is set to indicate the error.
ERRORS
i386_get_ldt() and i386_set_ldt() will fail if:
[EINVAL] An inappropriate parameter was used for start_sel or num_sels.
[EACCES] The caller attempted to use a descriptor that would circumvent protection or cause a failure.
