@OP: Your statement is correct, but you need to uncomment the echo command otherwise it will not work (there needs to be some kind of command, or you can use : instead (NOP)). It is best to use quotes around ${SID} so that the test won't break when SID is empty.
I receive windows files via the internet on my solaris server. Since unix doesn't handle blanks well I change the blanks to ? which works just fine. I take these files and ftp them to windows so our analysts can work with them. Recently I received a file with the following structure:

Here's my script
read number
if echo $number | grep ""
I want this "if" statement to return true only when numbers without letters is matched.
For example 45 - true, 923 - true, r5 - false, tg/f - false and so on.
In this script even a single digit number like "3" returns false.
Thanks. (1 Reply)

avc_get_initial_sid
avc_context_to_sid(3) SELinux API documentation avc_context_to_sid(3)NAME
avc_context_to_sid, avc_sid_to_context, avc_get_initial_sid - obtain and manipulate SELinux security ID's.
SYNOPSIS
#include <selinux/selinux.h>
#include <selinux/avc.h>
int avc_context_to_sid(security_context_t ctx, security_id_t *sid);
int avc_sid_to_context(security_id_t sid, security_context_t *ctx);
int avc_get_initial_sid(const char *name, security_id_t *sid);
DESCRIPTION
Security ID's (SID's) are opaque representations of security contexts, managed by the userspace AVC.
avc_context_to_sid returns a SID for the given context in the memory referenced by sid.
avc_sid_to_context returns a copy of the context represented by sid in the memory referenced by ctx. The user must free the copy with
freecon(3).
avc_get_initial_sid returns a SID for the kernel initial security identifier specified by name.
RETURN VALUE
avc_context_to_sid and avc_sid_to_context return zero on success. On error, -1 is returned and errno is set appropriately.
ERRORS
ENOMEM An attempt to allocate memory failed.
NOTES
As of libselinux version 2.0.86, SID's are no longer reference counted. A SID will be valid from the time it is first obtained until the
next call to avc_destroy(3). The sidget and sidput functions, formerly used to adjust the reference count, are no-ops and are deprecated.
