string vs. numeric
== is used when doing string comparison, and -eq is used for numeric comparisons. I typically add a function if something complex is being repeated, or the number of script statement repeats is numerous, such as a return code check. HTH

strcoll
STRCOLL(3) 1 STRCOLL(3) strcoll - Locale based string comparison SYNOPSIS
int strcoll (string $str1, string $str2) DESCRIPTION
Note that this comparison is case sensitive, and unlike strcmp(3) this function is not binary safe. strcoll(3) uses the current locale for doing the comparisons. If the current locale is C or POSIX, this function is equivalent to str- cmp(3). PARAMETERS
o $str1 - The first string. o $str2 - The second string. RETURN VALUES
Returns < 0 if $str1 is less than $str2; > 0 if $str1 is greater than $str2, and 0 if they are equal. CHANGELOG
