Numeric Comparisons

The most common test evaluation methods perform a comparison of two numerical values.

n1 -eq n2	Checks if n1 is equal to n2	`if [ $n1 -eq $n2 ] then do_something fi`
n1 -ge n2	Checks if n1 is greater than or equal to n2	`if [ $n1 -ge $n2 ] then do_something fi`
n1 -gt n2	Checks if n1 is greater than n2	`if [ $n1 -gt $n2 ] then do_something fi`
n1 -le n2	Checks if n1 less than or equal to n2	`if [ $n1 -le $n2 ] then do_something fi`
n1 -lt n2	Checks if n1 is less than n2	`if [ $n1 -lt $n2 ] then do_something fi`
*n1 -ne n2*	Checks if n1 is not equal to n2	`if [ $n1 -ne $n2 ] then do_something fi`
