Hello,
I kinda newbie in unix so I would like so help.I know that there is a command that compares two integer numbers test (eg. [ $1 -eq 0 ] #$1=0 ).I would like to know if it is possible to compare any number with another (eg. 2.3=0 or 3.7!=0 4.5>2.2).

strncmp
STRCMP(3) Linux Programmer's Manual STRCMP(3)
NAME
strcmp, strncmp - compare two strings
SYNOPSIS
#include <string.h>
int strcmp(const char *s1, const char *s2);
int strncmp(const char *s1, const char *s2, size_t n);
DESCRIPTION
The strcmp() function compares the two strings s1 and s2. 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 strncmp() function is similar, except it only compares the first (at most) n characters of s1 and s2.
RETURN VALUE
The strcmp() and strncmp() 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.
