Hints
The test command, is a shell builtin that is used to evaluate expressions in a shell script. It has various options for performing different types of tests, such as checking the type of a file, comparing the values of two variables, or testing the status of a command.
There are two syntaxes for using the test command.
$ test EXPRESSION
$ [ EXPRESSION ]
The "-gt", "-lt", and "-eq" operators are used in the shell to perform tests and comparisons on values. These operators are commonly used with the [ command (also known as the test command) to check the value of a variable or expression.
Here is a summary of the "-gt", "-lt", and "-eq" operators:
- "-gt": Greater than. This operator checks if the value on the left is greater than the value on the right.
- "-lt": Less than. This operator checks if the value on the left is less than the value on the right.
- "-eq": Equal to. This operator checks if the value on the left is equal to the value on the right.
