You don't mention which shell you are using. Assuming it's bash, the assignment seems correct, but the preceding if construct will not work. Replace the "eq" (should be -eq anyhow), which compares integers, with "==", which compares strings.

strncasecmp
STRCASECMP(3) Linux Programmer's Manual STRCASECMP(3)
NAME
strcasecmp, strncasecmp - compare two strings ignoring case
SYNOPSIS
#include <strings.h>
int strcasecmp(const char *s1, const char *s2);
int strncasecmp(const char *s1, const char *s2, size_t n);
DESCRIPTION
The strcasecmp() function compares the two strings s1 and s2, ignoring the case of the characters. It returns an integer less than, equal
to, or greater than zero if s1 is found, respectively, to be less than, to match, or be greater than s2.
The strncasecmp() function is similar, except it only compares the first n characters of s1.
RETURN VALUE
The strcasecmp() and strncasecmp() functions return an integer less than, equal to, or greater than zero if s1 (or the first n bytes
thereof) is found, respectively, to be less than, to match, or be greater than s2.
CONFORMING TO
4.4BSD, POSIX.1-2001.
